About the Upgrade Process
1
Upgrading is a multistage process in which procedures must be performed in a particular order. Follow
theprocess outlined in this high-level overview to ensure a smooth upgrade with a minimum of system
downtime.
CAUTION Make sure that you understand the entire upgrade process before you attempt to upgrade. If you
do not follow the safeguards, you might lose data and lose access to your servers. Without planning, you
might incur more downtime than is necessary.
You must complete the upgrade process in a specific order because you can lose data and server access.
Order is also important within each upgrade stage.
You can perform the upgrade process for each component in only one direction. For example, after you
upgrade to vCenter Server, you cannot revert to VirtualCenter 2.5. With backups and planning, you can
restore your original software records.
You must complete one procedure before you move to the next procedure. Follow the directions within each
procedure regarding the required sequence of minor substeps.
Because certain commands can simultaneously upgrade more than one stage, VMware recommends that
you understand the irreversible changes at each stage before you upgrade your production environments.
To ensure that your datacenter upgrade goes smoothly, you can use vCenter Update Manager to manage
the process for you.
vSphere upgrades proceed in the following sequence of tasks.
1
If your vSphere system includes VMware solutions or plug-ins, make sure they are compatible with the
vCenter Server version that you are upgrading to. See the VMware Product Interoperability Matrix at
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
2
If you are upgrading vSphere components that are part of a VMware View environment, see
“Upgrading vSphere Components Separately in a VMware View Environment,” on page 175.
3
Make sure your system meets vSphere hardware and software requirements.
See Chapter 3, “System Requirements,” on page 13.
4
If your vSphere deployment includes vCenter Server, upgrade vCenter Server.
See Chapter 4, “Upgrading to vCenter Server 5.0,” on page 27.
5
If you use VMware Update Manager, upgrade VMware Update Manager.
See Chapter 5, “Upgrading Update Manager,” on page 73.

How vSphere 5.0 Differs from
vSphere 4.x
2
vSphere 5.0 is a major upgrade from vSphere 4.x.
The following changes from vSphere 4.x affect vSphere installation and setup. For a complete list of new
features in vSphere 5.0, see the release notes.
Service Console is
removed
ESXi does not include a Service Console. You can perform most tasks that
you performed in the Service Console by using esxcli commands in the ESXi
Shell, by using vCLI commands, and by using VMware PowerCLI
commands. See Command-Line Management in vSphere 5.0 for Service Console
Users and Getting Started with vSphere Command-Line Interfaces.
ESXi does not have a
graphical installer
The graphical installer relied on the Service Console, which is not a part of
ESXi. ESXi retains the text-based installer.
vSphere Auto Deploy
and vSphere ESXi
Image Builder CLI
Before ESXi 5.0, ESXi was installed on the physical disk of each ESXi host.
With ESXi 5.0, you can load an ESXi image directly into memory by using
vSphere Auto Deploy. You can provision and reprovision large numbers of
ESXi hosts efficiently with vCenter Server, and manage ESXi updates and
patching by using an image profile. You can save host configuration such as
network or storage setup as a host profile and apply it to the host by using
Auto Deploy. You can use ESXi Image Builder CLI to create ESXi installation
images with a customized set of updates, patches, and drivers.
For complete information on using vSphere Auto Deploy and ESXi Image
Builder PowerCLI, see the vSphere Installation and Setup documentation.
Changes in the ESXi
installation and upgrade
process
ESXi 5.0 uses a single installer wizard for fresh installations and upgrades.
ESXi 5.0 also provides a new option for deploying ESXi directly into the host
memory with vSphere Auto Deploy. The vihostupdate and esxupdate
utilities are not supported for ESXi 5.0. You cannot upgrade or migrate to
ESXi 5.0 by using any command-line utility. After you have upgraded or
migrated to ESXi 5.0, you can upgrade or patch ESXi 5.0 hosts using vCLI
esxcli commands.
IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot
roll back to your version 4.x ESX or ESXi software. Back up your host before
you perform an upgrade or migration, so that, if the upgrade or migration
fails, you can restore your 4.x host.
See “ESXi 5.0.x Upgrade and Update Options,” on page 84.
VMware, Inc.

vSphere Upgrade
Installer caching
Instead of using a binary image to install the system, whatever bits were
used at boot time are cached to the system. This caching reduces installation
problems caused by accessing installation files across networks that are
under load.
NOTE Scripted installations cannot PXE boot a server and then obtain the
binary image from some other form of media.
Changes to partitioning
of host disks
All freshly installed hosts in vSphere 5.0 use the GUID Partition Table format
instead of the MSDOS-style partition label. This change supports ESXi
installation on disks larger than 2TB.
Newly installed vSphere 5.0 hosts use VMFS5, an updated version of the
VMware File System for vSphere 5.0. Unlike earlier versions, ESXi 5.0 does
not create VMFS partitions in second and successive disks.
Upgraded systems do not use GUID Partition Tables (GPT), but retain the
older MSDOS-based partition label.
12
VMware vCenter Server
Appliance
As an alternative to installing vCenter Server on a Windows machine,
vSphere 5.0 provides the VMware vCenter Server Appliance. The vCenter
Server Appliance is a preconfigured Linux-based virtual machine optimized
for running vCenter Server and associated services.
vSphere Web Client
The vSphere Web Client is a server application that provides a browserbased alternative to the traditional vSphere Client. You can use a Web
browser to connect to the vSphere Web Client to manage an ESXi host
through a vCenter Server.
VMware, Inc.
System Requirements
3
Systems running vCenter Server and ESXi instances must meet specific hardware and operating system
requirements.
If you are using Auto Deploy to provision ESXi hosts, see also the information about preparing for VMware
Auto Deploy in the vSphere Installation and Setup documentation.

ESXi Hardware Requirements
Make sure the host meets the minimum hardware configurations supported by ESXi 5.0.
Hardware and System Resources
To install and use ESXi 5.0, your hardware and system resources must meet the following requirements:
n
Supported server platform. For a list of supported platforms, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
n
ESXi 5.0 will install and run only on servers with 64-bit x86 CPUs.
n
ESXi 5.0 requires a host machine with at least two cores.
n
ESXi 5.0 supports only LAHF and SAHF CPU instructions.
VMware, Inc.
13
vSphere Upgrade
n
ESXi supports a broad range of x64 multicore processors. For a complete list of supported processors,
see the VMware compatibility guide at http://www.vmware.com/resources/compatibility.
n
ESXi requires a minimum of 2GB of physical RAM. VMware recommends 8GB of RAM to take full
advantage of ESXi features and run virtual machines in typical production environments.
n
To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must
be enabled on x64 CPUs.
n
One or more Gigabit or 10Gb Ethernet controllers. For a list of supported network adapter models, see
the VMware Compatibility Guide at http://www.vmware.com/resources/compatibility.
n
Any combination of one or more of the following controllers:
n
Basic SCSI controllers. Adaptec Ultra-160 or Ultra-320, LSI Logic Fusion-MPT, or most
NCR/Symbios SCSI.
n
RAID controllers. Dell PERC (Adaptec RAID or LSI MegaRAID), HP Smart Array RAID, or IBM
(Adaptec) ServeRAID controllers.
n
SCSI disk or a local, non-network, RAID LUN with unpartitioned space for the virtual machines.
n
For Serial ATA (SATA), a disk connected through supported SAS controllers or supported on-board
SATA controllers. SATA disks will be considered remote, not local. These disks will not be used as a
scratch partition by default because they are seen as remote.
NOTE You cannot connect a SATA CD-ROM device to a virtual machine on an ESXi 5.0 host. To use the
SATA CD-ROM device, you must use IDE emulation mode.
Storage Systems
ESXi 5.0 supports installing on and booting from the following storage systems:
n
SATA disk drives. SATA disk drives connected behind supported SAS controllers or supported onboard SATA controllers.
Supported SAS controllers include:
n
LSI1068E (LSISAS3442E)
n
LSI1068 (SAS 5)
n
IBM ServeRAID 8K SAS controller
n
Smart Array P400/256 controller
n
Dell PERC 5.0.1 controller
Supported on-board SATA include:
n
Intel ICH9
n
NVIDIA MCP55
n
ServerWorks HT1000
NOTE ESXi does not support using local, internal SATA drives on the host server to create VMFS
datastores that are shared across multiple ESXi hosts.
14
n
Serial Attached SCSI (SAS) disk drives. Supported for installing ESXi 5.0 and for storing virtual
machines on VMFS partitions.
n
Dedicated SAN disk on Fibre Channel or iSCSI
n
USB devices. Supported for installing ESXi 5.0. For a list of supported USB devices, see the VMware
Compatibility Guide at http://www.vmware.com/resources/compatibility.
VMware, Inc.
Chapter 3 System Requirements
ESXi Booting Requirements
vSphere 5.0 supports booting ESXi hosts from the Unified Extensible Firmware Interface (UEFI). With UEFI
you can boot systems from hard drives, CD-ROM drives, or USB media. Network booting or provisioning
with VMware Auto Deploy requires the legacy BIOS firmware and is not available with UEFI.
ESXi can boot from a disk larger than 2TB provided that the system firmware and the firmware on any addin card that you are using support it. See the vendor documentation.
NOTE Changing the boot type from legacy BIOS to UEFI after you install ESXi 5.0 might cause the host to
fail to boot. In this case, the host displays an error message similar to: Not a VMware boot bank. Changing
the host boot type between legacy BIOS and UEFI is not supported after you install ESXi 5.0.
Storage Requirements for ESXi 5.0 Installation
Installing ESXi 5.0 requires a boot device that is a minimum of 1GB in size. When booting from a local disk
or SAN/iSCSI LUN, a 5.2GB disk is required to allow for the creation of the VMFS volume and a 4GB scratch
partition on the boot device. If a smaller disk or LUN is used, the installer will attempt to allocate a scratch
region on a separate local disk. If a local disk cannot be found the scratch partition, /scratch, will be located
on the ESXi host ramdisk, linked to /tmp/scratch. You can reconfigure /scratch to use a separate disk or
LUN. For best performance and memory optimization, VMware recommends that you do not
leave /scratch on the ESXi host ramdisk.
To reconfigure /scratch, see the topic "Set the Scratch Partition from the vSphere Client" in the vSphere
Installation and Setup documentation.
Due to the I/O sensitivity of USB and SD devices the installer does not create a scratch partition on these
devices. As such, there is no tangible benefit to using large USB/SD devices as ESXi uses only the first 1GB.
When installing on USB or SD devices, the installer attempts to allocate a scratch region on an available local
disk or datastore. If no local disk or datastore is found, /scratch is placed on the ramdisk. You should
reconfigure /scratch to use a persistent datastore following the installation.
In Auto Deploy installations, the installer attempts to allocate a scratch region on an available local disk or
datastore. If no local disk or datastore is found /scratch is placed on ramdisk. You should
reconfigure /scratch to use a persistent datastore following the installation.
For environments that boot from a SAN or use Auto Deploy, it is not necessary to allocate a separate LUN
for each ESXi host. You can co-locate the scratch regions for many ESXi hosts onto a single LUN. The
number of hosts assigned to any single LUN should be weighed against the LUN size and the I/O behavior
of the virtual machines.
Recommendation for Enhanced ESXi Performance
To enhance performance, install ESXi on a robust system with more RAM than the minimum required and
with multiple physical disks.
For ESXi system requirements, see “ESXi Hardware Requirements,” on page 13.
VMware, Inc.
15
vSphere Upgrade
Table 3‑1. Recommendations for Enhanced Performance
System Element
Recommendation
RAM
ESXi hosts require more RAM than typical servers.
VMware recommends 8GB of RAM to take full advantage
of ESXi features and run virtual machines in typical
production environments. An ESXi host must have
sufficient RAM to run concurrent virtual machines. The
following examples are provided to help you calculate the
RAM required by the virtual machines running on the ESXi
host.
Operating four virtual machines with
Red Hat Enterprise Linux or Windows XP requires at least
3GB of RAM for baseline performance. This figure includes
approximately 1024MB for the virtual machines, 256MB
minimum for each operating system as recommended by
vendors.
Running these four virtual machines with 512MB RAM
requires that the ESXi host have approximately 4GB RAM,
which includes 2048MB for the virtual machines.
These calculations do not take into account possible
memory savings from using variable overhead memory for
each virtual machine. See vSphere Resource Management .
Dedicated Fast Ethernet adapters for virtual machines
Place the management network and virtual machine
networks on different physical network cards. Dedicated
Gigabit Ethernet cards for virtual machines, such as Intel
PRO 1000 adapters, improve throughput to virtual
machines with high network traffic.
Disk location
Place all data that your virtual machines use on physical
disks allocated specifically to virtual machines.
Performance is better when you do not place your virtual
machines on the disk containing the ESXi boot image. Use
physical disks that are large enough to hold disk images
that all the virtual machines use.
VMFS5 partitioning
The ESXi installer creates the initial VMFS volumes on the
first blank local disk found. To add disks or modify the
original configuration, use the vSphere Client. This practice
ensures that the starting sectors of partitions are 64Kaligned, which improves storage performance.
NOTE For SAS-only environments, the installer might not
format the disks. For some SAS disks, it is not possible to
identify whether the disks are local or remote. After the
installation, you can use the vSphere Client to set up
VMFS.
Processors
Faster processors improve ESXi performance. For certain
workloads, larger caches improve ESXi performance.
Hardware compatibility
Use devices in your server that are supported by ESXi 5.0
drivers. See the Hardware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
ESXi Support for 64-Bit Guest Operating Systems
ESXi offers support for several 64-bit guest operating systems.
For a complete list of operating systems supported for ESXi, see the VMware Compatibiity Guide at
http://www.vmware.com/resources/compatibility/search.php.
16
VMware, Inc.
Chapter 3 System Requirements
Hosts running virtual machines with 64-bit guest operating systems have the following hardware
requirements:
n
For AMD Opteron-based systems, the processors must be Opteron Rev E or later.
n
For Intel Xeon-based systems, the processors must include support for Intel Virtualization Technology
(VT). Many servers that include CPUs with VT support might have VT disabled by default, so you must
enable VT manually. If your CPUs support VT ,but you do not see this option in the BIOS, contact your
vendor to request a BIOS version that lets you enable VT support.
To determine whether your server has 64-bit VMware support, you can download the CPU Identification
Utility from the VMware Web site.
vCenter Server and vSphere Client Hardware Requirements
The vCenter Server system is a physical machine or virtual machine with access to a supported database.
The vCenter Server system must meet specific requirements. The vCenter Server machines must meet the
hardware requirements.
vCenter Server Hardware Requirements
Table 3‑2. Minimum Hardware Requirements for vCenter Server
vCenter Server Hardware
Requirement
CPU
Two 64-bit CPUs or one 64-bit dual-core processor.
Processor
2.0GHz or faster Intel 64 or AMD 64 processor. The
Itanium (IA64) processor is not supported. Processor
requirements might be higher if the database runs on the
same machine.
Memory
4GB RAM. Memory requirements might be higher if the
database runs on the same machine.
vCenter Server includes several Java services: VMware
VirtualCenter Management Webservices (Tomcat),
Inventory Service, and Profile-Driven Storage Service.
When you install vCenter Server, you select the size of
your vCenter Server inventory to allocate memory for these
services. The inventory size determines the maximum JVM
heap settings for the services. You can adjust this setting
after installation if the number of hosts in your
environment changes. See the recommendations in
Table 3-3.
Disk storage
4GB. Disk requirements might be higher if the vCenter
Server database runs on the same machine. In vCenter
Server 5.0, the default size for vCenter Server logs is 450MB
larger than in vCenter Server 4.x. Make sure the disk space
allotted to the log folder is sufficient for this increase.
Microsoft SQL Server 2008 R2 Express disk
Up to 2GB free disk space to decompress the installation
archive. Approximately 1.5GB of these files are deleted
after the installation is complete.
Networking
Gigabit connection recommended.
The recommended JVM heap settings for vCenter Server depend on your inventory size.

vCenter Server Software Requirements
Make sure that your operating system supports vCenter Server. vCenter Server requires a 64-bit operating
system, and the 64-bit system DSN is required for vCenter Server to connect to its database.
For a list of supported operating systems, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
20
VMware, Inc.
Chapter 3 System Requirements
vCenter Server requires the Microsoft .NET 3.5 SP1 Framework. If it is not installed on your system, the
vCenter Server installer installs it. The .NET 3.5 SP1 installation might require Internet connectivity to
download more files.
NOTE If your vCenter Server host machine uses a non-English operating system, install both the
Microsoft .NET Framework 3.5 SP1 and Microsoft .NET Framework 3.5 Language Pack through Windows
Update. Windows Update automatically selects the correct localized version for your operating system.
The .NET Framework installed through the vCenter Server installer includes only the English version.
If you plan to use the Microsoft SQL Server 2008 R2 Express database that is bundled with vCenter Server,
Microsoft Windows Installer version 4.5 (MSI 4.5) is required on your system. You can download MSI 4.5
from the Microsoft Web site. You can also install MSI 4.5 directly from the vCenter Server autorun.exe
installer.
The VMware vCenter Server Appliance can be deployed only on hosts that are running ESX version 4.x or
ESXi version 4.x or later.
vSphere Client and vSphere Web Client Software Requirements
Make sure that your operating system supports the vSphere Client.
For the most current, complete list of supported operating systems for the vSphere Client and the
vSphere Web Client, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
The vSphere Client requires the Microsoft .NET 3.5 SP1 Framework. If it is not installed on your system, the
vSphere Client installer installs it. The .NET 3.5 SP1 installation might require Internet connectivity to
download more files.
The following browsers are supported for the vSphere Web Client:
n
Microsoft Internet Explorer 7 and 8
n
Mozilla Firefox 3.6
The vSphere Web Client requires the Adobe Flash Player version 10.1.0 or later to be installed with the
appropriate plug-in for your browser.
Providing Sufficient Space for System Logging
ESXi 5.0 uses a new log infrastructure. If your host is deployed with Auto Deploy, or if you set up a log
directory separate from the default location in a scratch directory on the VMFS volume, you might need to
change your current log size and rotation settings to ensure that enough space for system logging exists.
All vSphere components use this infrastructure. The default values for log capacity in this infrastructure
vary, depending on the amount of storage available and on how you have configured system logging. Hosts
that are deployed with Auto Deploy store logs on a RAM disk, which means that the amount of space
available for logs is small.
If your host is deployed with Auto Deploy, reconfigure your log storage in one of the following ways:
n
Redirect logs over the network to a remote collector.
n
Redirect logs to a NAS or NFS store.
You might also want to reconfigure log sizing and rotations for hosts that are installed to disk, if you
redirect logs to nondefault storage, such as a NAS or NFS store.
You do not need to reconfigure log storage for ESXi hosts that use the default configuration, which stores
logs in a scratch directory on the VMFS volume. For these hosts, ESXi 5.0 autoconfigures logs to best suit
your installation, and provides enough space to accommodate log messages.

Required Ports for vCenter Server
The VMware vCenter Server system must be able to send data to every managed host and receive data from
every vSphere Client. To enable migration and provisioning activities between managed hosts, the source
and destination hosts must be able to receive data from each other.
For information about ports required for the vCenter Server Appliance, see “Required Ports for the vCenter
Server Appliance,” on page 23.
VMware uses designated ports for communication. Additionally, the managed hosts monitor designated
ports for data from the vCenter Server system. If a firewall exists between any of these elements and
Windows firewall service is in use, the installer opens the ports during the installation. For custom firewalls,
you must manually open the required ports. If you have a firewall between two managed hosts and you
want to perform source or target activities, such as migration or cloning, you must configure a means for the
managed hosts to receive data.
NOTE In Microsoft Windows Server 2008, a firewall is enabled by default.
Table 3‑12. Ports Required for Communication Between Components
22
Port
Description
80
vCenter Server requires port 80 for direct HTTP connections. Port 80 redirects requests to HTTPS
port 443. This redirection is useful if you accidentally use http://server instead of https://server.
If you use a custom Microsoft SQL database (not the bundled SQL Server 2008 database) that is
stored on the same host machine as the vCenter Server, port 80 is used by the SQL Reporting Service.
When you install vCenter Server, the installer will prompt you to change the HTTP port for vCenter
Server. Change the vCenter Server HTTP port to a custom value to ensure a successful installation.
Microsoft Internet Information Services (IIS) also use port 80. See “Conflict Between vCenter Server
and IIS for Port 80,” on page 24.
389
This port must be open on the local and all remote instances of vCenter Server. This is the LDAP port
number for the Directory Services for the vCenter Server group. The vCenter Server system needs to
bind to port 389, even if you are not joining this vCenter Server instance to a Linked Mode group. If
another service is running on this port, it might be preferable to remove it or change its port to a
different port. You can run the LDAP service on any port from 1025 through 65535.
If this instance is serving as the Microsoft Windows Active Directory, change the port number from
389 to an available port from 1025 through 65535.
443
The default port that the vCenter Server system uses to listen for connections from the vSphere
Client. To enable the vCenter Server system to receive data from the vSphere Client, open port 443 in
the firewall.
The vCenter Server system also uses port 443 to monitor data transfer from SDK clients.
If you use another port number for HTTPS, you must use ip-address:port when you log in to the
vCenter Server system.

902
The default port that the vCenter Server system uses to send data to managed hosts. Managed hosts
also send a regular heartbeat over UDP port 902 to the vCenter Server system. This port must not be
blocked by firewalls between the server and the hosts or between hosts.

Required Ports for the vCenter Server Appliance
The VMware vCenter Server system must be able to send data to every managed host and receive data from
every vSphere Client. For migration and provisioning activities between managed hosts, the source and
destination hosts must be able to receive data from each other.
For information about ports required for vCenter Server on Windows, see “Required Ports for vCenter
Server,” on page 22.
VMware uses designated ports for communication. Additionally, the managed hosts monitor designated
ports for data from the vCenter Server system. The vCenter Server Appliance is preconfigured to use the
ports listed in Table 3-13. For custom firewalls, you must manually open the required ports. If you have a
firewall between two managed hosts and you want to perform source or target activities, such as migration
or cloning, you must configure a means for the managed hosts to receive data.

Conflict Between vCenter Server and IIS for Port 80
vCenter Server and Microsoft Internet Information Service (IIS) both use port 80 as the default port for direct
HTTP connections. This conflict can cause vCenter Server to fail to restart after the installation of vSphere
Authentication Proxy.
Problem
vCenter Server fails to restart after the installation of vSphere Authentication Proxy is complete.
Cause
If you do not have IIS installed when you install vSphere Authentication Proxy, the installer prompts you to
install IIS. Because IIS uses port 80, which is the default port for vCenter Server direct HTTP connections,
vCenter Server fails to restart after the installation of vSphere Authentication Proxy is complete. See
“Required Ports for vCenter Server,” on page 22.
Solution
u
24
To resolve a conflict between IIS and vCenter Server for port 80, take one of the following actions.
Option
Description
If you installed IIS before installing
vCenter Server
Change the port for vCenter Server direct HTTP connections from 80 to
another value.
If you installed vCenter Server
before installing IIS
Before restarting vCenter Server, change the binding port of the IIS default
Web site from 80 to another value.
VMware, Inc.
Chapter 3 System Requirements
DNS Requirements for vSphere
You install vCenter Server, like any other network server, on a machine with a fixed IP address and wellknown DNS name, so that clients can reliably access the service.
Assign a static IP address and host name to the Windows server that will host the vCenter Server system.
This IP address must have a valid (internal) domain name system (DNS) registration.
Ensure that the ESXi host management interface has a valid DNS resolution from the vCenter Server and all
vSphere Clients and vSphere Web Clients. Ensure that the vCenter Server has a valid DNS resolution from
all ESXi hosts and all vSphere Clients and vSphere Web Clients.
Ensure that the vCenter Server is installed on a machine that has a resolvable fully qualified domain name
(FQDN). To check that the FQDN is resolvable, type nslookup your_vCenter_Server_fqdn at a command line
prompt. If the FQDN is resolvable, the nslookup command returns the IP and name of the domain controller
machine.
Ensure that DNS reverse lookup returns a fully qualified domain name when queried with the IP address of
the vCenter Server. When you install vCenter Server, the installation of the web server component that
supports the vSphere Client fails if the installer cannot look up the fully qualified domain name of the
vCenter Server from its IP address. Reverse lookup is implemented using PTR records. To create a PTR
record, see the documentation for your vCenter Server host operating system.
If you use DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server
computer name is updated in the domain name service (DNS). Ping the computer name to test the
connection. For example, if the computer name is host-1.company.com, run the following command in the
Windows command prompt:
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.

Update Manager Hardware Requirements
You can run Update Manager on any system that meets the minimum hardware requirements.
Minimum hardware requirements for Update Manager vary depending on how Update Manager is
deployed. If the database is installed on the same machine as Update Manager, requirements for memory
size and processor speed are higher. To ensure acceptable performance, verify that your system meets the
minimum hardware requirements.

Update Manager uses a SQL Server or Oracle database. You should use a dedicated database for
Update Manager, not a database shared with vCenter Server, and should back up the database periodically.
Best practice is to have the database on the same computer as Update Manager or on a computer in the local
network.
Depending on the size of your deployment, Update Manager requires a minimum amount of free space per
month for database usage. For more information about space requirements, see the VMware vSphere Update
Manager Sizing Estimator.
For more information about ESXi 5.x and vCenter Server 5.x hardware requirements, see Chapter 3, “System
Requirements,” on page 13.
Supported Operating Systems and Database Formats
Update Manager works with specific databases and operating systems.
The Update Manager server requires a 64-bit Windows system.
NOTE Make sure the system on which you are installing Update Manager server is not an Active Directory
domain controller.
The Update Manager plug-in requires the vSphere Client, and works with the same operating systems as
the vSphere Client.
Update Manager scans and remediates Windows and Linux virtual machines for VMware Tools and virtual
hardware upgrades.
The Update Manager server requires SQL Server or Oracle database. Update Manager can handle smallscale environments using the bundled SQL Server 2008 R2 Express. For environments with more than 5
hosts and 50 virtual machines, create either an Oracle or a SQL Server database for Update Manager. For
large scale environments, you should set up the Update Manager database on a different computer than the
Update Manager server and the vCenter Server database.

About the vCenter Server 5.0.x Upgrade
VMware supports in-place upgrades on 64-bit systems from vCenter Server 4.x and vCenter Server 5.0 to
vCenter Server 5.0.x.
You can upgrade VirtualCenter 2.5 Update 6 or later and vCenter Server 4.0.x to vCenter Server 5.0.x by
installing vCenter Server 5.0.x on a new machine and migrating the existing database. This upgrade method
makes it possible to upgrade from a 32-bit system to a 64-bit system. Alternatively, if the VirtualCenter or
vCenter Server database is on a remote machine, you can upgrade the database.
vCenter Server 5.0.x can manage ESX 3.5.x/ESXi 3.5.x hosts in the same cluster with ESX 4.x/ESXi 4.x hosts.
NOTE You cannot upgrade a vCenter Server 4.x instance that is running on Windows XP Professional x64
Edition to vCenter Server 5.0, because vCenter Server 5.0.x does not support Windows XP Professional x64.

vCenter Server Prerequisites
The following items are prerequisites for completing the upgrade to vCenter Server:
n
VMware vCenter Server 5.0 installation media.
n
License keys for all purchased functionality.
If you do not have the license key, you can install in evaluation mode and use the vSphere Client to
enter the license key later. If the vCenter Server that you are upgrading is in evaluation mode, after the
upgrade, the time remaining in your evaluation period is decreased by the amount already used. For
example, if you used 20 days of the evaluation period before upgrading, your remaining evaluation
period after the upgrade is 40 days.
If you do not intend to use evaluation mode, make sure that you have new license keys during an
upgrade. Old license keys are not supported in vCenter Server 5.0.
30
n
The installation path of the previous version of vCenter Server must be compatible with the installation
requirements for Microsoft Active Directory Application Mode (ADAM/AD LDS). The installation path
cannot contain any of the following characters: non-ASCII characters, commas (,), periods (.),
exclamation points (!), pound signs (#), at signs (@), or percentage signs (%). If your previous version of
vCenter Server does not meet this requirement, you must perform a clean installation of vCenter
Server 5.0.
n
Make sure the system on which you are installing vCenter Server is not an Active Directory primary or
backup domain controller.
n
Either remove any ESX Server 2.x hosts from the VirtualCenter or vCenter Server inventory or upgrade
these hosts to 3.5 or later.
n
If you are upgrading to vCenter Server 5.0, update any ESX/ESXi 4.1 hosts to version 4.1 Update 1 or

checking in VirtualCenter 2.5, the hosts are disconnected from vCenter Server, and you must
reconnect them.
n
If the vCenter Server 4.x environment that you are upgrading includes Guided Consolidation 4.x,
uninstall Guided Consolidation before upgrading to vCenter Server 5.0.
n
If you use vCenter Guided Consolidation Service in the VirtualCenter 2.x environment, complete the
consolidation plan before you upgrade to vCenter Server 5.0. The upgrade to vCenter Server 5.0 does
not preserve or migrate any data gathered by the vCenter Guided Consolidation Service. After the
upgrade, all of the data is cleared, and you cannot restore it.
n
Back up the SSL certificates that are on the VirtualCenter or vCenter Server system before you upgrade
to vCenter Server 5.0. The default location of the SSL certificates is %allusersprofile%\Application
Data\VMware\VMware VirtualCenter.
n
vCenter Server 5.0 uses TCP/IP Ports 80 and 443 for the VMware vSphere Web client. You cannot run
vCenter Server on the same machine as a Web server using TCP/IP port 80 (HTTP) or port 443 (HTTPS)
because doing so causes port conflicts.
n
Verify that the fully qualified domain name (FQDN) of the system where you will upgrade vCenter
Server is resolvable. To check that the FQDN is resolvable, type nslookup your_vCenter_Server_fqdn at
a command line prompt. If the FQDN is resolvable, the nslookup command returns the IP and name of
the domain controller machine.
n
Verify that DNS reverse lookup returns a fully qualified domain name when queried with the IP
address of the vCenter Server. When you upgrade vCenter Server, the installation of the web server
component that supports the vSphere Client fails if the installer cannot look up the fully qualified
domain name of the vCenter Server from its IP address. Reverse lookup is implemented using PTR
records. To create a PTR record, see the documentation for your vCenter Server host operating system.
n
If you use DHCP instead of a manually assigned (static) IP address for vCenter Server, make sure that
the vCenter Server computer name is updated in the domain name service (DNS). Test this is by
pinging the computer name. For example, if the computer name is host-1.company.com, run the
following command in the Windows command prompt:
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.
n
Ensure that the ESXi host management interface has a valid DNS resolution from the vCenter Server
and all vSphere Clients. Ensure that the vCenter Server has a valid DNS resolution from all ESXi hosts
and all vSphere Clients.

If your database server is not supported by vCenter Server, perform a database upgrade to a supported
version or import your database into a supported version. See “Supported Database Upgrades,” on
page 34.
31
vSphere Upgrade
n
Perform a complete backup of the VirtualCenter Server or vCenter Server database before you begin the
upgrade. The VirtualCenter 2.5 database schema is not compatible with vCenter Server 5.0. The vCenter
Server 5.0 installer upgrades your existing VirtualCenter Server database schema with extra fields,
making the database unusable by VirtualCenter 2.5 Update 6.
To remove the DBO role, you can migrate all objects in the DBO schema to a custom schema. See the
VMware knowledge base article at http://kb.vmware.com/kb/1036331.
n
You must have login credentials, the database name, and the database server name that will be used by
the vCenter Server database. The database server name is typically the ODBC System database source
name (DSN) connection name for the vCenter Server database.
n
Review “Supported Database Upgrades,” on page 34.
Prerequisites for Microsoft SQL Databases
n
To use a newly supported Microsoft SQL database, such as Microsoft SQL 2008, you do not need to
perform a clean installation of vCenter Server if your existing database is also Microsoft SQL Server. For
example, you can upgrade a Microsoft SQL Server 2000 database to Microsoft SQL Server 2005 or
Microsoft SQL Server 2008 and then upgrade VirtualCenter 2.5 Update 6 or higher to vCenter
Server 5.0. When you migrate the database from Microsoft SQL Server 2000 to Microsoft SQL Server
2005 or higher, set the compatibility level of the database to 90.
n
JDK 1.6 must be installed on the vCenter Server machine. In addition, sqljdbc4.jar must be added to
the CLASSPATH variable on the machine where vCenter Server is to be upgraded. If it is not installed
on your system, the vCenterServer installer installs it. The JDK 1.6 installation might require Internet
connectivity.
n
If you are upgrading from VirtualCenter 2.5 Update 6 with the bundled SQL Server 2005 Express (by
installing vCenter Server 5.0 on a different machine and keeping the database), you do not have to
perform a clean installation of vCenter Server.
n
Your system DSN must be using the SQL Native Client driver.

Prerequisites for Oracle Databases
n
To use a newly supported Oracle database, such as Oracle 11g, you do not need to perform a clean
installation of vCenter Server if your existing database is also Oracle. For example, you can upgrade
your existing Oracle 9i database to Oracle 10g or Oracle 11g and then upgrade vCenter Server 4.x to
vCenter Server 5.0.
n
The JDBC driver file must be included in the CLASSPATH variable.

execute on dbms_lock to <user>
unlimited tablespace to <user> # To ensure sufficient space
After the upgrade is complete, you can optionally remove the following permissions from the user
profile: create any sequence and create any table.
By default, the RESOURCE role has the CREATE PROCEDURE, CREATE TABLE, and CREATE
SEQUENCE privileges assigned. If the RESOURCE role lacks these privileges, grant them to the
vCenter Server database user.
Prerequisite for IBM DB2 Databases
To use a newly supported IBM DB2 database, you must use vCenter Server 4.0 Update 1 or higher. Previous
releases of VirtualCenter or vCenter Server do not support DB2 databases.
vCenter Server Database Patch and Configuration Requirements
After you choose a database type, make sure you understand the configuration and patch requirements for
the database.
NOTE vCenter Update Manager also requires a database. VMware recommends that you use separate
databases for vCenter Server and vCenter Update Manager.
vCenter Server databases require a UTF code set.
If your VirtualCenter 2.5 Update 6 database is not supported for upgrade to vCenter Server 5, first upgrade
your database and then upgrade to vCenter Server. You also can import your database into a database that
is supported for upgrade to vCenter Server.
If your database is not listed in Table 4-2, see “Supported Database Upgrades,” on page 34.
For information about specific database versions and service pack configurations supported with vCenter
Server, see the VMware Product Interoperability Matrixes.

Database Type
Configuration Notes
IBM DB2
If the database is not local to the vCenter Server system, install the IBM Data Server
Runtime Client.
Install the IBM DB2 native client according to the IBM instructions for your DB2 version.
Ensure that the DB2 binaries directory (typically C:\Program Files\IBM\SQLLIB\BIN) is
in the system path. DB2 might be installed at a different location.
You might need to restart the Microsoft Windows machine for the service to recognize the
change in the environment variable.
Ensure that the machine has a valid ODBC data source name (DSN) entry.
NOTE This database is not supported for the vCenter Server Appliance.
Microsoft SQL Server 2008
R2 Express
Bundled database that you can use for small deployments of up to 5 hosts and 50 virtual
machines.
You cannot install the bundled database during an upgrade to vCenter Server. To use the
bundled database, Microsoft SQL Server 2008 R2 Express must be already installed or you
must perform a clean installation of vCenter Server.
NOTE This database is not supported for the vCenter Server Appliance.
Microsoft SQL Server 2005
Ensure that the machine has a valid ODBC DSN entry.
NOTE This database is not supported for the vCenter Server Appliance.
Microsoft SQL Server 2008
Ensure that the machine has a valid ODBC DSN entry.
NOTE This database is not supported for the vCenter Server Appliance.
Oracle
For Oracle 10g R2, if necessary, first apply patch 10.2.0.4 (or later) to the client and server.
You can then apply patch 5699495 to the client.
Ensure that the machine has a valid ODBC DSN entry.
After you complete the vCenter Server installation, take the following steps:
n Apply the latest patch to the Oracle client and server.
n Copy the Oracle JDBC driver (ojdbc14.jar or ojdbc5.jar) to the vCenter Server
installation directory, in the tomcat\lib subdirectory: vCenter install
location\Infrastructure\tomcat\lib.
The vCenter Server installer attempts to copy the Oracle JDBC driver from the Oracle client
location to the vCenter Server installation directory. If the Oracle JDBC driver is not found
in the Oracle client location, the vCenter Server installer prompts you to copy the file
manually. You can download the file from the oracle.com Web site.
Supported Database Upgrades
When you upgrade, migrate, or update to vCenter Server 5.0 or 5.0.1, make sure that the upgraded version
supports your database.
Table 4-3 lists the database types that you can use with vCenter Server 5.0 or 5.0.1. The purpose of this list is
to describe the vCenter Server Upgrade scenarios for each database type. For a list of supported database

Supported Upgrade, Migration, or Update
Configure vCenter Server to Communicate with the Local Database
The machine on which you install or upgrade to vCenter Server must have a computer name that is 15
characters or fewer. If your database is located on the same machine on which vCenter Server will be
installed, and you have recently changed the name of this machine to comply with the name-length
requirement, make sure the vCenter Server DSN is configured to communicate with the new name of the
machine.
Changing the vCenter Server computer name impacts database communication if the database server is on
the same computer with vCenter Server. If you changed the machine name, you can verify that
communication remains intact.
The name change has no effect on communication with remote databases. You can skip this procedure if
your database is remote.
NOTE The name-length limitation applies to the vCenter Server system. The data source name (DSN) and
remote database systems can have names with more than 15 characters.
Check with your database administrator or the database vendor to make sure all components of the
database are working after you rename the server.
Prerequisites
n
VMware, Inc.
Make sure the database server is running.

n
Make sure that the vCenter Server computer name is updated in the domain name service (DNS).
Ping the computer name to test this connection. For example, if the computer name is
host-1.company.com, run the following command in the Windows command prompt:
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.
Procedure
1
Update the data source information, as needed.
2

Back Up VirtualCenter 2.5 Update 6 or Higher
You must back up a VirtualCenter system to ensure that you can restore your previous configuration of
VirtualCenter if the upgrade does not complete successfully. The only way to recover from an unsuccessful
upgrade is to use your backed up database and SSL certificates.
You cannot roll back your database to the previous database schema.
Procedure
1
Make a full backup of the VirtualCenter 2.5 Update 6 or higher database.
See your database documentation.

About the vCenter Host Agent Pre-Upgrade Checker
The vCenter Host Agent Pre-Upgrade Checker produces a report showing known issues that might prevent
a successful upgrade of the vCenter Host Agent software.
To ensure a successful upgrade to vCenter Server 5, you must diagnose and fix any potential problems on
the managed ESX/ESXi hosts. You can run the vCenter Host Agent Pre-Upgrade Checker for in-place
upgrades from vCenter Server 4.x to vCenter Server 5.0.
vCenter Host Agent runs on all managed ESX/ESXi hosts. This software coordinates actions received from
vCenter Server. When you add a host to vCenter Server, the agent is installed on the physical ESX/ESXi host.
When you upgrade to vCenter Server 5, the agent residing on each ESX/ESXi host must be upgraded as well.
36
VMware, Inc.
Chapter 4 Upgrading to vCenter Server 5.0
During a vCenter Server upgrade, the existing agent software is uninstalled and the updated agent software
is installed in its place. If the upgrade fails, the updated agent software might not be installed and the host
might become unreachable by VirtualCenter 2.5 Update 6 or later, vCenter Server 4.x, or by
vCenter Server 5.0. To avoid this condition, you can run the vCenter Host Agent Pre-Upgrade Checker
before you try to upgrade to vCenter Server 5.
The vCenter Host Agent Pre-Upgrade Checker checks to make sure that the agent software is ready to be
upgraded. Some of the checks include checking to make sure that the host is reachable, the disk space is
sufficient, the network is functioning, the file system is intact, and required patches are applied. Each time
you run the tool, the system queries VMware.com and downloads any new updates for the tool. This action
ensures that as new upgrade issues are discovered, the tool remains as useful as possible.
IMPORTANT A successful vCenter Host Agent pre-upgrade check does not guarantee a successful upgrade to
vCenter Server 5. An upgrade to vCenter Server involves multiple components, and the tool checks only one
component: the vCenter Host Agent. Also, the tool checks only known issues. Other issues might be present
that the tool does not check.
The vCenter Host Agent Pre-Upgrade Checker does not fix the reported issues. You must resolve the
reported issues manually and rerun the tool to verify that the issues are resolved.
For the procedure to run the vCenter Host Agent Pre-Upgrade Checker, see “Run the vCenter Host Agent
Pre-Upgrade Checker,” on page 37.
Run the vCenter Host Agent Pre-Upgrade Checker
The vCenter Host Agent Pre-Upgrade Checker reports known issues that might prevent a successful
upgrade of the vCenter Host Agent software.
For more information about the vCenter Host Agent Pre-Upgrade Checker, see “About the vCenter Host
Agent Pre-Upgrade Checker,” on page 36.

Downtime During the vCenter Server Upgrade
When you upgrade vCenter Server, downtime is required for vCenter Server.
Expect downtime for vCenter Server as follows:
n
The upgrade requires vCenter Server to be out of production for 40-50 minutes, depending on the size
of the database. The database schema upgrade takes approximately 10-15 minutes of this time. This
estimate does not include host reconnection after the upgrade.
If Microsoft .NET Framework is not installed on the machine, a reboot is required before starting the
vCenter Server installation.
n
VMware Distributed Resource Scheduler does not work while the upgrade is in progress. VMware HA
does work during the upgrade.
Downtime is not required for the ESX/ESXi hosts that vCenter Server is managing, or for virtual machines
that are running on the hosts.

DNS Load Balancing Solutions and vCenter Server Datastore Naming
vCenter Server 5.x uses different internal identifiers for datastores than earlier versions of vCenter Server.
This change affects the way that you add shared NFS datastores to hosts and can affect upgrades to vCenter
Server 5.x.
vCenter Server versions before version 5.0 convert datastore host names to IP addresses. For example, if you
mount an NFS datastore by the name \\nfs-datastore\folder, pre-5.0 vCenter Server versions convert the
name nfs-datastore to an IP address like 10.23.121.25 before storing it. The original nfs-datastore name is
lost.
This conversion of host names to IP addresses causes a problem when DNS load balancing solutions are
used with vCenter Server. DNS load balancing solutions themselves replicate data and appear as a single
logical datastore. The load balancing happens during the datastore host name-to-IP conversion by resolving
the datastore host name to different IP addresses, depending on the load. This load balancing happens
outside vCenter Server and is implemented by the DNS server. In vCenter Server versions before version
5.0, features like vMotion do not work with such DNS load balancing solutions because the load balancing
causes one logical datastore to appear as several datastores. vCenter Server fails to perform vMotion
because it cannot recognize that what it sees as multiple datastores are actually a single logical datastore that
is shared between two hosts.
To solve this problem, vCenter Server versions 5.0 and later do not convert datastore names to IP addresses
when you add datastores. This enables vCenter Server to recognize a shared datastore, but only if you add
the datastore to each host by the same datastore name. For example, vCenter Server does not recognize a
datastore as shared between hosts in the following cases.
n
The datastore is added by IP address to host1 and by hostname to host2.
n
The datastore is added by hostname to host1, and by hostname.vmware.com to host2.
For vCenter Server to recognize a datastore as shared, you must add the datastore by exactly the same name
to every host.
Datastore Names and Upgrades to vCenter Server 5.x
In vCenter Server versions before version 5.0, vCenter Server database stores datastore paths in the old
format, as IP addresses. The upgrade to vCenter Server 5.x converts these paths to the new format. If you
use a DNS load balancing solution with shared datastores, before you upgrade to vCenter Server 5.x, make
sure that every shared datastore is mounted on each of its hosts with the exact same name.
The upgrade to vCenter Server 5.x might also fail from a lack of sufficient memory if you use a DNS load
balancing solution with shared datastores. In a large vCenter Server database, the conversion of datastore
paths to the new format can require a large amount of memory. See Knowledge Base article 2015055.

Microsoft SQL Database Set to Unsupported Compatibility Mode Causes
vCenter Server Installation or Upgrade to Fail
vCenter Server installation with a Microsoft SQL database fails when the database is set to compatibility
mode with an unsupported version.
Problem
The following error message appears: The DB User entered does not have the required permissions
needed to install and configure vCenter Server with the selected DB. Please correct the following
error(s): %s
Cause
The database version must be supported for vCenter Server. For SQL, even if the database is a supported
version, if it is set to run in compatibility mode with an unsupported version, this error occurs. For example,
if SQL 2008 is set to run in SQL 2000 compatibility mode, this error occurs.
Solution
u
Make sure the vCenter Server database is a supported version and is not set to compatibility mode with
an unsupported version. See “vCenter Server Database Patch and Configuration Requirements,” on
page 33
vCenter Server Upgrade Fails When You Restore a Microsoft SQL 2000 Backup
to the vCenter Server Database
A vCenter Server upgrade fails if you restore a Microsoft SQL 2000 database backup to the vCenter Server
database.
Problem
When the failure occurs, the following error message appears: DBuser entered doesn't have the required
permissions to install and configure vCenter Server with the selected DB.
Cause
This problem can occur when you upgrade to vCenter Server from VirtualCenter 2.x. VirtualCenter 2.x
supports SQL 2000, which VMware does not support for vCenter Server 5.0. When you restore a backup
from SQL Server 2000 on SQL Server 2005, the restored database is set to compatibility level 80, which is
compatible with SQL Server 2000. The minimum supported compatibility level for vCenter Server 5.0
databases is 90, which is compatible with SQL Server 2005.
Solution
u
Before you upgrade to vCenter Server, change the compatibility level to 90, for compatibility with SQL
Server 2005, or to 100, for compatibility with SQL Server 2008.

Updating Version 3.5 Hosts in High Availability Clusters Before Upgrading
vCenter Server
Before you upgrade vCenter Server to version 5.0, make sure that any ESX 3.5 hosts that are in a vSphere
HA cluster are updated to a patch level that supports High Availability.
If a version 3.5 ESX or ESXi host is in a vSphere HA cluster and is not updated to a patch level that supports
High Availability, you cannot add that host to the HA cluster or remove it from maintenance mode after the
associated vCenter Server is upgraded to version 5.0.
Update ESX 3.5 hosts to ESX350-201012401-SG PATCH, and update ESXi 3.5 hosts to ESXe350-201012401-IBG PATCH. If you have updated your version 3.5 hosts to these patch levels but you still cannot add the
hosts to a HA cluster or remove them from maintenance mode after the associated vCenter Server is
upgraded to version 5.0, you might need to apply the following patches.

Upgrade vCenter Server 4.x to vCenter Server 5.0 on the same machine if the vCenter Server 4.x instance is
on a 64-bit machine.
This procedure requires downtime for the vCenter Server that you are upgrading. You do not need to turn
off virtual machines.
If an earlier version of vCenter Server is on your machine, the vCenter Server installer detects and upgrades
it. If the upgrade fails, no automatic rollback occurs to the previous vCenter Server version.
In-place upgrade to vCenter 5.0 is not supported on Microsoft Windows XP.
NOTE If your vSphere system includes VMware solutions or plug-ins, make sure they are compatible with
the vCenter Server version that you are upgrading to. See the VMware Product Interoperability Matrix at
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
If the vCenter Server that you are upgrading from has plug-ins or plug-in versions that are incompatible
with vCenter Server 5.0, for example vSphere Converter or Update Manager, these plug-ins will be
unregistered during the upgrade process.

with the proper operation of the vSphere Client. See “Upgrade the vSphere Client,” on page 62. Review
the topics in “After You Upgrade vCenter Server,” on page 61 for other postupgrade actions you might
want to take.
Upgrade to vCenter Server on a Different Machine and Upgrade the
Database
When you upgrade to vCenter Server, you can migrate vCenter Server to a new machine. One reason for
doing this is to move from a 32-bit machine to a 64-bit machine.
You can also use the data migration tool to migrate a SQL Server Express database that is installed by the
vCenter Server installer on the same machine as vCenter Server. If you use a different database that is
installed on the vCenter Server machine, you must back up and move the database manually to the new
machine. If the database is installed on a different machine from vCenter Server, you can leave the database
in place and create a DSN on the destination machine to connect to it.
The VirtualCenter or vCenter Server configuration settings that you can migrate with the tool include:
n
LDAP data.
n
Port settings for the HTTP, HTTPS, heartbeat, Web services, LDAP, and LDAP SSL ports.
n
Certificates stored in the SSL folder.
VMware, Inc.
43
vSphere Upgrade
n
License.
n
Database data for a bundled SQL Server Express database only.
If VMware vCenter Update Manager or vCenter Orchestrator is installed on the same machine as vCenter
Server, you can use the data migration tool to migrate configuration data for these products. You can also
use the tool to migrate the vCenter Update Manager database if it is a SQL Server Express database installed
on the same machine as vCenter Update Manager and vCenter Server. You cannot use the data migration
tool to migrate the vCenter Orchestrator database. See the documentation for vCenter Update Manager and
vCenter Orchestrator for information about upgrading these products.
IMPORTANT If your vSphere system includes VMware solutions or plug-ins, make sure they are compatible
with the vCenter Server version that you are upgrading to. See the VMware Product Interoperability Matrix
at http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
Prerequisites
If you are using a remote database, either remove any ESX Server 2.x hosts from the VirtualCenter or
vCenter Server inventory or upgrade these hosts. If you are not using a remote database, you do not need to
remove ESX Server 2.x hosts from the VirtualCenter or vCenter Server inventory or upgrade them.
However, they will not be connected to the vCenter Server after the upgrade.
Stop the VMware VirtualCenter Server service before you perform this upgrade.

Back Up VirtualCenter or vCenter Server Configuration with the Data Migration
Tool
The data migration tool allows you to back up VirtualCenter or vCenter Server configuration data such as
port settings, SSL certificates, and licensing information. The data migration tool can restore these settings
when you upgrade to vCenter Server on a new 64-bit host machine.
If your database is a SQL Server Express database that is local to the VirtualCenter or vCenter Server
machine, the data migration tool will back up the database and restore it to the destination machine.
If VMware vCenter Orchestrator is installed on the same machine as VirtualCenter or vCenter Server, the
data migration tool will back up the vCenter Orchestrator configuration and restore it to the destination
machine. The data migration tool does not back up and restore the vCenter Orchestrator database. See
Installing and Configuring VMware vCenter Orchestrator for information about upgrading vCenter
Orchestrator using the data migration tool.
If VMware vCenter Update Manager is installed on the same machine as VirtualCenter or vCenter Server,
the data migration tool will back up the vCenter Update Manager configuration and restore it to the
destination machine. If vCenter Update Manager uses a SQL Server Express database that is local to the
source machine, the data migration tool will back up the database and restore it to the destination machine.
The data migration tool does not back up and restore patch binaries. See Installing and Administering VMware

After you use the data migration tool to back up the configuration of a vCenter Server system with a
nonbundled database, you complete the migration to a new machine by using the data migration tool
to install vCenter Server and restore the vCenter Server configuration on the destination machine.
Restore the vCenter Server Configuration and the Bundled Database and Install
vCenter Server on the Destination Machine
After you use the data migration tool to back up the configuration of a vCenter Server system with the
bundled SQL Server Express database, you complete the migration to a new machine by using the data
migration tool to install vCenter Server and restore the vCenter Server configuration on the destination
machine.
Use this procedure if you are migrating a vCenter Server that uses the bundled SQL Server Express
database. The data migration tool restores the database to the new machine and launches the vCenter Server
installer.
If you are migrating a vCenter Server that uses a database other than the bundled SQL Server Express
database, see “Restore the vCenter Server Configuration and Nonbundled Database and Install vCenter
Server on the New Machine,” on page 54.

You can install the VI Client 2.5, the vSphere Client 4.x, and vSphere Client 5.0 on the same machine. After
you upgrade vCenter Server, be sure to upgrade the vSphere Client to the same version to avoid
compatibility problems that might interfere with the proper operation of the vSphere Client.
The vSphere Client upgrade operation requires no downtime. You do not need to power off virtual
machines or clients.
Prerequisites
n
Verify that you have the vCenter Server installer or the vSphere Client installer.
n
Verify that you are a member of the Administrators group on the system.
n
Verify that the system has an Internet connection.
Procedure
1
(Optional) Use Add/Remove Programs from the Windows Control Panel to remove any previous
vCenter Server client.
You do not need to remove earlier versions of vCenter Server clients. These are useful if you need to

address of the Windows machine on which vCenter Server is installed and the user name and password of a
user on that machine.
If you do not have the VI Client 2.5 installed and you use vSphere Client to connect to VirtualCenter 2.5, the
vSphere Client prompts you to download and install the VI Client 2.5. After you install the VI Client 2.5,
you can use the vSphere Client log-in interface to connect to VirtualCenter 2.5 or vCenter Server 5.0.
What to do next
Use the vSphere Client to connect to the vCenter Server IP address with your Windows login user name and
password. Use the login credentials appropriate to the Windows machine on which vCenter Server is
installed. The vCenter Server user name and password might be different than the user name and password
you use for ESXi.
If the vSphere Client displays security alerts and exceptions when you log in or perform some operations,
such as opening performance charts or viewing the Summary tab, this might mean that your Internet
Explorer (IE) security settings are set to High. If your IE security settings are set to High, enable the Allow
scripting of Internet Explorer web browser control setting in IE.

Using a License Server to Manage Version 3.5 ESX or ESXi Hosts
vCenter Server 5.0 requires a license server to manage ESX/ESXi version 3.5 hosts.
vCenter Server 5.0 does not require a license server to manage ESX or ESXi version 4.x hosts.
If you have a license server installed, you can configure your newly installed or upgraded vCenter Server to
use the license server. If you do not have a license server installed, you can download the VMware License
Server from the VMware Web site at
http://downloads.vmware.com/d/details/esx_35_licenseserver_dt/dGViZGVoKmJkZXBo. After you have
installed the license server, configure vCenter Server to use it.
See the information about configuring vCenter Server to use a license server in the vCenter Server and Host
Management documentation.
You can also upgrade legacy hosts to manage them through vCenter Server without a license server.
License Server Upgrade Scenarios
If you upgrade to vCenter Server 5.0 and you want the vCenter Server system to manage version 3.5 ESX or
ESXi hosts, verify that the license server is running and that vCenter Server 5.0 is configured to access the
license server.
To configure vCenter Server to access a license server, see the vCenter Server and Host Management

Linked Mode Considerations for vCenter Server
Consider several issues before you configure a Linked Mode group.
Before you configure a Linked Mode group, consider the following issues.
n
If you upgrade a vCenter Server that is part of a Linked Mode group, it will be removed from the
group. vCenter Server does not support Linked Mode groups that contain both version 5.0 and earlier
versions of vCenter Servers. After all vCenter Servers in the group are upgraded to version 5.0, you can
rejoin them.
n
Each vCenter Server user sees the vCenter Server instances on which they have valid permissions.
n
When you set up your vCenter Server Linked Mode group, you must install the first vCenter Server as
a standalone instance because you do not yet have a remote vCenter Server machine to join. Subsequent
vCenter Server instances can join the first vCenter Server or other vCenter Server instances that have
joined the Linked Mode group.
n
If you join a vCenter Server to a standalone instance that is not part of a domain, you must add the
standalone instance to a domain and add a domain user as an administrator.
n
The vCenter Server instances in a Linked Mode group do not need to have the same domain user login.
The instances can run under different domain accounts. By default, they run as the LocalSystem
account of the machine on which they are running, which means that they are different accounts.
n
During vCenter Server installation, if you enter an IP address for the remote instance of vCenter Server,
the installer converts it into a fully qualified domain name.
n
You cannot join a Linked Mode group during the upgrade procedure when you are upgrading from
VirtualCenter 25 to vCenter Server 5.0. You can join after the upgrade to vCenter Server is complete.
n
CAUTION If you need to uninstall and reinstall vCenter Server on more than one member of a Linked
Mode group, do so with a single vCenter Server at a time. Uninstalling and reinstalling multiple linked
vCenter Servers at the same time is not supported, and can cause errors that prevent vCenter Server
from connecting to vCenter Inventory Service. If it is necessary to uninstall and reinstall multiple linked
vCenter Servers at the same time, isolate them from the Linked Mode group first, and rejoin them to the
Linked Mode group after the reinstallation is complete.
Linked Mode Prerequisites for vCenter Server
Prepare the vCenter Server system for joining a Linked Mode group.
Before joining a vCenter Server to a Linked Mode group, review “Linked Mode Considerations for vCenter
Server,” on page 64.
All the requirements for standalone vCenter Server systems apply to Linked Mode systems.
The following requirements apply to each vCenter Server system that is a member of a Linked Mode group:
64
n
Linked Mode groups that contain both vCenter Server 5.0 and earlier versions of vCenter Server are not
supported. The vSphere Client does not function correctly with vCenter Servers in groups that have
both version 5.0 and earlier versions of vCenter Server. Do not join a version 5.0 vCenter Server to
earlier versions of vCenter Server, or an earlier version of vCenter Server to a version 5.0 vCenter
Server. Upgrade any vCenter Server instance to version 5.0 before joining it to a version 5.0 vCenter
Server.
n
To join a Linked Mode group the vCenter Server must be in evaluation mode or licensed as a Standard
edition. vCenter Server Foundation and vCenter Server Essentials editions do not support Linked
Mode.
n
DNS must be operational for Linked Mode replication to work.
VMware, Inc.
Chapter 4 Upgrading to vCenter Server 5.0
n
The vCenter Server instances in a Linked Mode group can be in different domains if the domains have a
two-way trust relationship. Each domain must trust the other domains on which vCenter Server
instances are installed.
n
When adding a vCenter Server instance to a Linked Mode group, the installer must be run by a domain
user who is an administrator on both the machine where vCenter Server is installed and the target
machine of the Linked Mode group.
n
All vCenter Server instances must have network time synchronization. The vCenter Server installer
validates that the machine clocks are not more than five minutes apart.
Join a Linked Mode Group After a vCenter Server Upgrade
After you upgrade to vCenter Server 5.0, you can join the system to a Linked Mode group. A Linked Mode
group allows you to log in to any single instance of vCenter Server in the group and view and manage the
inventories of all the vCenter Server systems in the group.
Prerequisites
See “Linked Mode Prerequisites for vCenter Server,” on page 64.
NOTE Joining a version 5.0 vCenter Server to older versions of vCenter Server is not supported.
Procedure
1
From the Start menu, select All Programs > VMware > vCenter Server Linked Mode Configuration.
2
Click Next.
3
Select Modify linked mode configuration and click Next.
4
Click Join vCenter Server instance to an existing linked mode group or another instance and click
Next.
5
Type the server name and LDAP port number of any remote vCenter Server that is or will be a member
of the group and click Next.
If you enter an IP address, the installer converts it to a fully qualified domain name.
6
If the vCenter Server installer detects a role conflict, select how to resolve the conflict.
A conflict results if the joining system and the Linked Mode group each contain a role with the same
name but with different privileges.
VMware, Inc.
Option
Description
Yes, let VMware vCenter Server
resolve the conflicts for me
Click Next.
The role on the joining system is renamed to vcenter_namerole_name where
vcenter_name is the name of the vCenter Server system that is joining the
Linked Mode group and role_name is the name of the original role.
No, I'll resolve the conflicts myself
To resolve the conflicts manually:
a Using the vSphere Client, log in to the vCenter Server system that is
joining the Linked Mode group using an account with Administrator
privileges.
b Rename the conflicting role.
c Close the vSphere Client session and return to the vCenter Server
installer.
d Click Back, and click Next.
The installation continues without conflicts.
65
vSphere Upgrade
7
Click Finish.
vCenter Server restarts. Depending on the size of your inventory, the change to Linked Mode might
take from a few seconds to a few minutes to complete.
The vCenter Server instance is now part of a Linked Mode group. It might take several seconds for the
global data (such as user roles) that are changed on one machine to be visible on the other machines. The
delay is usually 15 seconds or less. It might take a few minutes for a new vCenter Server instance to be
recognized and published by the existing instances, because group members do not read the global data
very often.
After you form a Linked Mode group, you can log in to any single instance of vCenter Server and view and
manage the inventories of all the vCenter Servers in the group.
What to do next
For information about Linked Mode groups, see the vCenter Server and Host Management documentation.
Set the Maximum Number of Database Connections After a vCenter Server
Upgrade
By default, a vCenter Server creates a maximum of 50 simultaneous database connections. If you configure
this value to less than 50 in the previous version of vCenter Server and then perform the upgrade to vCenter
Server 5.0, the upgrade restores the default setting of 50. If you configure this value to more than 50 in the
previous version of vCenter Server, after the upgrade to vCenter Server 5.0, the system retains the previous
value. You can reconfigure the nondefault setting.
You might want to increase the number of database connections if the vCenter Server frequently performs
many operations and performance is critical. You might want to decrease this number if the database is
shared and connections to the database are costly. Do not change this value unless your system has one of
these problems.
Perform this task before you configure the authentication for your database. For more information about
configuring authentication, see the documentation for your database.
Procedure
1
From a vSphere Client host that is connected to a vCenter Server system, select Administration >
vCenter Server Configuration.
2
Click Database.
3
In the Current vCenter Server menu, select the appropriate server.
4
In Maximum number, type the number.
5
Restart the vCenter Server.
The new database setting takes effect.
Restore VirtualCenter or vCenter Server
You can restore the previous VirtualCenter or vCenter Server configurations if you have a full backup of
your VirtualCenter or vCenter database and the previous VirtualCenter and vCenter SSL certificates.
Prerequisites
Iin the event of a system failure or disaster, you might need some or all of the following items to restore
VirtualCenter and its components. Follow your company disaster recovery guidelines for storage and
handling of these items.

Data\VMware\VMware VirtualCenter directory.
6
Make sure the system DSN points to the database.
Upgrading Datastore and Network Permissions
In previous releases of vCenter Server, datastores and networks inherited access permissions from the
datacenter. In vCenter Server 4.0 and later, datastores and networks have their own set of privileges that
control access to them. You might have toassign privileges manually, depending on the access level you
require.
In vCenter Server 5.0, users are granted the No Access role on all new managed objects, including datastores
and networks. This means, by default, users cannot view or perform operations on them. All existing objects
in vCenter Server maintain their permissions after the upgrade. To determine whether to assign permissions
to existing datastores and networks, the upgrade process uses the datacenter's Read-only privilege.
n
Read-only privilege is nonpropagating (not inherited by child objects). VMware assumes that access
privileges should not be assigned to datastores and networks. You must update your roles to include
the new datastore and network privileges. These privileges are required for users to view and perform
operations on these objects.
n
Read-only privilege is propagating (inherited by child objects). VMware assumes that access privileges
should be assigned to datastores and networks so that users can view them and perform basic
operations that require access. The default minimum privileges are assigned during the upgrade
process.
After the upgrade process, if your roles require users to have more privileges, for example, the ability to
delete a datastore or network, update your permission roles.

Update Datastore Permissions
You must change Read-only nonpropagating datastore permissions to propagating datastore permissions in
order for users to access the datastores. You can assign datastore permissions on datastores or folders
containing datastores.
Prerequisites
Before performing the upgrade procedure, determine which users need access to each datastore and which
privileges each user needs. If necessary, define new datastore roles or modify the Database Consumer
sample role. This sample role assigns the Allocate Space privilege to the datastore, which enables users to
perform basic virtual machine operations, such as creating clones and taking snapshots. In addition,
organize your datastores in folders that coincide with users' access needs.
NOTE The Read-only propagating permission on a datacenter, in addition to all permissions you have set,
will be kept intact after the datastore permissions upgrade.
Procedure
1
Log in to vSphere Client as an administrator.
2
On the Home page, click Datastores to display the datastores in the inventory.
3
Select the datastore or datastore folder and click the Permissions tab.
4
Right-click in the Permissions tab and from the context pop-up menu, choose Add Permission.

In the Assigned Role pane, assign a role.
n
To assign specific datastore privileges defined in a role by your company, choose the custom role.
n
To migrate read-only nonpropagating datacenter permissions to propagating datastore
permissions, choose Datastore Consumer (sample). This role assigns the Allocate Space privilege
to users, which is required so that users can consume space on the datastores on which this role is
granted. In order to perform a space-consuming operation, such as creating a virtual disk or taking
a snapshot, the user must also have the appropriate virtual machine privileges granted for these
operations.
n
To assign Read-only datastore privileges, choose Read-only.
This role enables users to browse the datastore without giving them other datastore privileges. For
example, choose Read-only for users who need to attach CD/DVD-ROM ISO images to a datastore.
6
Select Propagate to Child Objects.
7
In the Users and Groups pane, click Add.
8
Select the users and groups for whom to add the role.
To select multiple names, control-click each additional name.
9
Click OK.
All users are added to the Users and Groups list for this role.
10
Click OK.
The datastore is saved with the new permissions.
NOTE You need to set up permissions for new datastores that you create. By default, new datastores are
created under the datacenter folder in the inventory. You can move it into a datastore folder, as appropriate.

Network Privileges
In VMware vSphere 4.0 and higher, networks have their own set of access control privileges. As a result,
you might need to reconfigure your permissions to grant the new network privileges. This is required if you
have nonpropagating Read-only permission set on the datacenter.

Upgrading Update Manager
5
You can upgrade Update Manager 1.0 Update 6 and Update Manager 4.x to Update Manager 5.0.
You can install Update Manager 5.0 only on a 64-bit operating system. If you are running an earlier version
of Update Manager on a 32-bit platform, you must either back up and restore your database manually, or
use the data migration tool to back up the existing data on the 32-bit machine, and then restore your data on
the 64-bit machine on which you are installing Update Manager 5.0.
When you upgrade Update Manager, you cannot change the installation path and patch download location.
To change these parameters, you must install a new version of Update Manager rather than upgrade.
Previous versions of Update Manager use a 512-bit key and self-signed certificate and these are not replaced
during upgrade. If you require a more secure 2048-bit key, you can either perform a fresh installation of
Update Manager 5.0, or use the Update Manager Utility to replace the existing certificate.
Scheduled tasks for virtual machine patch scan and remediation are not removed during the upgrade. After
the upgrade, you can edit and remove scheduled scan tasks that exist from previous releases. You can
remove existing scheduled remediation tasks but you cannot edit them.
Virtual machine patch baselines are removed during the upgrade. Existing scheduled tasks that contain
them run normally and ignore only the scanning and remediation operations that use virtual machine patch
baselines.
You must upgrade the Update Manager database during the Update Manager upgrade. You can select
whether to keep your existing data in the database or to replace it during the upgrade.

Upgrade the Update Manager Server
To upgrade an instance of Update Manager that is installed on a 64-bit machine, you must first upgrade
vCenter Server to a compatible version.
The Update Manager 5.0 release allows upgrades from Update Manager 1.0 Update 6 and Update Manager
4.x.
Prerequisites
n
Ensure that you grant the database user the required set of privileges. See the Preparing the Update
Manager Database chapter in Installing and Administering VMware vSphere Update Manager.
n
Stop the Update Manager service and back up the Update Manager database. The installer upgrades
the database schema, making the database irreversibly incompatible with previous Update Manager
versions.

Upgrading and Migrating Your Hosts
6
After you upgrade vCenter Server, and vSphere Update Manager if you are using Update Manager,
upgrade or migrate VMware ESX 4.x and ESXi 4.x hosts to ESXi 5.0.
These topics are intended for administrators who are upgrading ESX, ESXi, and virtual machines from
ESX 4.x/ESXi 4.x to ESXi 5.0.
This chapter includes the following topics:

“After You Upgrade or Migrate Hosts,” on page 144
Preparing to Upgrade Hosts
For a successful upgrade of your hosts, understand and prepare for the changes that are involved.
Best Practices for ESXi Upgrades and Migrations
When you upgrade or migrate hosts, you must understand and follow the best practices process for a
successful upgrade or migration.
For a successful upgrade or migration, follow these best practices:
1
2
Make sure that you understand the ESXi upgrade process, the effect of that process on your existing
deployment, and the preparation required for the upgrade.
n
If your vSphere system includes VMware solutions or plug-ins, make sure they are compatible
with the vCenter Server version that you are upgrading to. See the VMware Product
Interoperability Matrix at
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
n
Read “Preparing to Upgrade Hosts,” on page 77 to understand the changes in configuration and
partitioning between ESXi 4.x and ESXi 4.x and ESXi 5.0, the upgrade and migration scenarios that
are supported, and the options and tools available to perform the upgrade or migration.
n
Read the VMware vSphere 5.0 Release Notes for known installation issues.
n
If your vSphere installation is in a VMware View environment, see “Upgrading vSphere
Components Separately in a VMware View Environment,” on page 175.
Prepare your system for the upgrade.
n
VMware, Inc.
Make sure your current ESX or ESXi version is supported for migration or upgrade. See
“Supported Upgrades and Updates to ESXi 5.0.x,” on page 86.
77
vSphere Upgrade
n
Make sure your system hardware complies with ESXI 5.0 requirements. See Chapter 3, “System
Requirements,” on page 13 and the VMware Compatibility Guide, at
http://www.vmware.com/resources/compatibility/search.php. Check for system compatibility, I/O
compatibility (network and HBA cards), storage compatibility, and backup software compatibility.
Server hardware for ESXi 5.0 must be 64-bit compatible. Intel VT must be enabled in the host BIOS.
n
Make sure that sufficient disk space is available on the host for the upgrade or migration.
Migrating from ESX 4.x to ESXi 5.0 requires 50MB of free space on your VMFS datastore.
n
If a SAN is connected to the host, detach the fibre before continuing with the upgrade or migration.
Do not disable HBA cards in the BIOS.
NOTE This step does not apply to ESX hosts that boot from the SAN and have the Service Console
on the on the SAN LUNs. You can disconnect LUNs that contain the VMFS datastore and do not
contain the Service Console.
3
Back up your host before performing an upgrade or migration, so that, if the upgrade fails, you can
restore your 4.x host.
IMPORTANT Once you have upgraded or migrated your host to ESXi 5.0, you cannot roll back to your
version 4.x ESX or ESXi software.
4
Depending on the upgrade or migration method you choose, you might need to migrate or power off
all virtual machines on the host. See the instructions for your upgrade or migration method.
5
After the upgrade or migration, test the system to ensure that the upgrade or migration completed
successfully.
6
Reapply your host licenses. See “Reapplying Licenses After Upgrading to ESXi 5.0,” on page 145.
7
Consider setting up a syslog server for remote logging, to ensure sufficient disk storage for log files.
Setting up logging on a remote host is especially important for hosts with limited local storage.
Optionally, you can install the vSphere Syslog Collector to collect logs from all hosts. See “Providing
Sufficient Space for System Logging,” on page 21. For information about setting up and configuring
syslog and a syslog server, setting up syslog from the host profiles interface, and installing vSphere
Syslog Collector, see the vSphere Installation and Setup documentation.
8
If the upgrade or migration was unsuccessful, and you backed up your version 4.x host, you can restore
your host.
Files and Configuration Settings Affected by the Migration or Upgrade to ESXi
5.0
The migration or upgrade from ESX 4.x or ESXi 4.x to ESXi 5.0 does not migrate all host configuration files
and settings.
After the upgrade, you must reconfigure some host settings.
78
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
Migrating ESX 4.x Files and Settings to ESXi 5.0
The upgrade process preserves as much of the ESX host configuration as possible. However, because of the
architectural differences between ESX 4.x and ESXi 5.0 architecture, many configuration files cannot be
migrated when you select the Migrate option in the ESXi installation or upgrade wizard.
Pertinent VMware files, such as /etc/vmware/esx.conf are migrated, but many existing settings such as
third-party agents and scripts, cannot be migrated.
NOTE If a host contains customizations, such as third-party VIBS or drivers, upgrading with the standard
VMware installer ISO will result in the loss of those customizations, and possibly an unstable system. Use
ESXi Image Builder CLI to create a customized ESXi installer ISO file that includes the VIBs or drivers. See
the information on Image Builder in the vSphere Installation and Setup documentation.

Firewall Configuration Changes After Migration or Upgrade to ESXi 5.0
The migration or upgrade from ESX/ESXi 4.x to ESXi 5.0 results in several changes to the host firewall
configuration.
When you migrate from ESX 4.x to ESXi 5.0, the ESX 4.x rulesets list is replaced by the new rulesets list in
ESXi 5.0. The following configuration from the /etc/vmware/esx.conf file is preserved:
n
The existing enabled/disabled status.
n
The allowedip added by esxcfg-firewall.
Ruleset files that are added by the user and customized firewall rules created in ESX 4.x. are not preserved
after the migration. In the first boot after the migration, for those rulesets that don't have entries in the ESX
4.x /etc/vmware/esx.conf file, the ESXi 5.0 firewall loads the default enabled status.
After the migration to ESXi 5.0, the default block policy is set to false (PASS all traffic by default) on ESXi 5.0
only when both blockIncoming and blockOutgoing values of the default policy are false in the ESX
4.x /etc/vmware/esx.conf file. Otherwise the default policy is to deny all traffic.
Custom ports that were opened by using the ESX/ESXi 4.1 esxcfg-firewall command do not remain open
after the upgrade to ESXi 5.0. The configuration entries are ported to the esx.conf file by the upgrade, but
the corresponding ports are not opened. See the information about ESXi firewall configuration in the vSphere
Security documentation.
IMPORTANT The ESXi firewall in ESXi 5.0 does not allow per-network filtering of vMotion traffic. Therefore,
you must install rules on your external firewall to ensure that no incoming connections can be made to the
vMotion socket.
Resource Pool Settings Affected by the Upgrade from ESX 4.x to ESXi 5.0
After the upgrade to ESXi 5.0, ESX 4.x resource pool settings might be insufficient to start all virtual
machines in the pool.
The upgrade to ESXi 5.0 affects the amount of memory available to the host system. As a result, in resource
pools that are set to use nearly all of the resources available, some virtual machines might not have enough
resources to start after the upgrade. When this happens, a system alert will be issued. You can find this alert
by pressing Alt + F11 in the ESXi direct console. Reconfigure the resource pools to solve the problem.
VMware, Inc.
81
vSphere Upgrade
SSH Configuration Affected by Upgrading or Migrating to ESXi 5.0
The host SSH configuration is migrated only for upgrades from ESXi 4.1 to ESXi 5.0
SSH configuration is not migrated for ESX 4.x hosts or ESXi 4.0 hosts. For these hosts, SSH access is disabled
during the upgrade or migration process. You can reenable SSH access in the direct console. See the
information on enabling SSH access in the vSphere Installation and Setup documentation.
Networking Changes in ESXi 5.0
Some ESX 4.x and ESXi 4.x network settings stored in /etc/sysconfig/network are migrated in the upgrade
or migration to ESXi 5.0. In the migration to ESXi 5.0, ESX Service Console virtual NICs (vswifs) are
converted to ESXi virtual NICs (vmks).
The distributed port group or dvPort that the virtual NICs connect to is also migrated. The Service Console
port group is renamed as the Management Network port group. When vswifs are migrated to vmks, they
are numbered to follow any existing vmk in sequence. For example, if the version 4.x ESX host has virtual
NICs vmk0, vmk1, and vswif0, after the migration the new ESXi configuration will be vmk0, vmk1, and
vmk2, where vmk2 is the management interface.
When virtual NICs are configured to use DHCP, a setting controls whether DHCP sets the default route and
host name in addition to installing an IPv4 address. In ESX this setting is PEERDNS. In ESXi, the setting is
DhcpDNS. The PEERDNS value for ESX Service Console virtual NICs is migrated to the DhcpDNS setting
for the ESXi virtual NICs. The DhcpDNS setting preserves the ESX configuration for default route and host
name as well as the IPv4 address.
The migration from ESX 4.x to ESXi 5.0 also preserves manually assigned IPv4 and IPv6 addresses, default
route, and host-specific IPv4 and IPv6 routes.
When you upgrade from ESXi 4.x to ESXi 5.x, the default maximum number of ports for a virtual switch
changes from 64 to 128. To keep the same maximum number of ports that you have in ESXi 4.x, set the value
explicitly before you upgrade, using the vSphere Client.
ESX hosts have two IP stacks, one for the vmkernel and one for the Service Console. Because ESXi hosts
have only one IP stack, the migration cannot preserve both ESX default routes. After migration, the ESX
Service Console default route becomes the single ESXi default route, replacing the vmkernel route. The
change to a single ESXi default route might cause loss of connectivity for routed nonmanagement traffic that
originates from vmkernel. To restore vmkernel networking, you can configure static routes in addition to
the default route.
All vswif interfaces are migrated to vmk interfaces. If a conflict is detected between two interfaces, one is left
in disabled state. The upgrade disables any conflicting kernel IP addressing in favor of the management
interface.
The migration to ESXi 5.0 disables any existing vmk virtual NIC that meets the following conditions.
n
The vmk virtual NIC has a manually configured (static) IP address.
n
The IP address is in the same subnet as a vswif virtual NIC that is being migrated to a switch containing
the vmk virtual NIC.
n
The vmk and vswif NICs are both on the same virtual switch.
For example, if vswif0, with IP address 192.0.2.1/24 on vswitch1, is migrated to a switch containing vmk0,
with IP address 192.0.2.2/24, also on vswitch1, after the migration, vmk0 will be disabled.
ESX 4.x Service Console Port Group Removed in Migration to ESXi 5.0
Because ESXi 5.0 has no Service Console, migrating from ESX 4.x to ESXi 5.0 removes the Service Console
port group.
After the migration to ESXi 5.0, a new port group, the Management Network port group, is created.
82
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
If any of your ESX hosts require the Service Console port group to support an existing service, you can write
a firstboot script to recreate the port group after the migration. See the information on the %firstboot
command in “Installation and Upgrade Script Commands,” on page 117.
Partitioning Changes from ESX 4.x to ESXi 5.0
The ESXi partition scheme used in ESXi 5.0 differs from that of earlier ESX and ESXi versions. ESXi 5.0 does
not have the Service Console partition found in ESX.
How these changes affect your host depends on whether you are upgrading to ESXi 5.0 or performing a
fresh installation.
Partitioning in New ESXi 5.0 Installations
In new installations, several new partitions are created for the boot banks, the scratch partition, and the
locker. New ESXi 5.0 installations use GUID Partition Tables (GPT) instead of MSDOS-based partitioning.
The partition table is fixed as part of the binary image, and is written to the disk at the time the system is
installed. The ESXi installer leaves the scratch and VMFS partitions blank, and ESXi creates them when the
host is rebooted for the first time after installation or upgrade. The scratch partition is 4GB. The rest of the
disk is formatted as a VMFS5 partition.
NOTE The installer can create multiple VFAT partitions. The VFAT designation does not always indicate
that the partition is a scratch partition. In some cases, a VFAT partition can lie idle.
Partitioning in Upgraded ESXi 5.0 Hosts
Upgraded systems do not use GUID Partition Tables (GPT), but retain the older MSDOS-based partition
label.
For most ESXi 4.x hosts, the partition table is not rewritten in the upgrade to ESXi 5.0. The partition table is
rewritten for systems that have lopsided bootbanks. Lopsided boot banks can occur in systems that are
upgraded from ESXi 3.5 to ESXi 4.x, and then upgraded directly to ESXi 5.0.
For ESX hosts, the partitioning structure is changed to resemble that of an ESXi 4.x host. The VMFS3
partition is retained and a new MSDOS-based partition table overwrites the existing partition table.
For ESX hosts, any data stored in custom user created partitions inside the Service Console is not preserved
in the migration to ESXi 5.0.
Upgraded hosts do not have a scratch partition. Instead, the scratch directory is created and accessed off of
the VMFS volume. Each of the other partitions, such as the bootbanks, locker and vmkcore are identical to
that of any other system.
In upgraded hosts, the VMFS partition is not upgraded from VMFS3 to VMFS5. ESXi 5.0 is compatible with
VMFS3 partitions. You can upgrade the partition to VMFS5 after the host is upgraded to ESXi 5.0. See the
information on upgrading datastores to VMFS5 in the vSphere Storage documentation.
Upgraded hosts, which keep the older MSDOS-based partitioning, do not support installing ESXi on a single
physical disk or LUN larger than 2TB. To install ESXi on a disk or LUN larger than 2TB, you must do a fresh
installation.
NOTE The ESXi 5.0 installer cannot detect ESX 2.x instances or VMFS2 datastores. You cannot migrate ESX
2.x instances to ESXi 5.0 or preserve VMFS2 datastores in an upgrade to ESXi 5.0. Instead, perform a fresh
installation of ESXi 5.0.
For the VMFS partition on the disk to be preserved during an upgrade to ESXi 5.0, the partition must be
physically located after the boot partition, which is partition 4, and the extended partition on the disk (8192
+ 1835008 sectors). Any system that has a VMFS partition after the 1843200 sector mark can keep that VMFS
partition, regardless of whether it was initially installed with ESX 3.5 or 4.x.
VMware, Inc.
83
vSphere Upgrade
For systems in which the VMFS partition is placed on a different drive from the boot drive, the entire
contents of the boot drive is overwritten during the upgrade. Any extra data on the disk is erased.
ESXi 5.0.x Upgrade and Update Options
VMware provides several ways to upgrade and update ESX/ESXi hosts.
vSphere Update
Manager
vSphere Update Manager is software for upgrading, migrating, updating,
and patching clustered hosts, virtual machines, and guest operating systems.
Update Manager orchestrates host and virtual machine upgrades. If your site
uses vCenter Server, VMware recommends that you use Update Manager.
For instructions about conducting an orchestrated host upgrade, see “Using
vSphere Update Manager to Perform Orchestrated Host Upgrades,” on
page 99. For instructions about conducting an orchestrated virtual machine
upgrade, see “Perform an Orchestrated Upgrade of Virtual Machines with
vSphere Update Manager,” on page 151. For complete documentation about
Update Manager, see the Installing and Administering VMware vSphere Update
Manager.
Update, Upgrade or
migrate interactively
using an ESXi installer
ISO image on CD/DVD
or USB flash drive
You can run the ESXi 5.0.x installer from a CD/DVD or USB flash drive to do
an interactive upgrade or migration. This method is appropriate for
deployments with a small number of hosts. The installer works the same as
for a fresh installation, but if you select a target disk that already contains an
ESX/ESXi 4.x or ESXi 5.0 installation, the installer upgrades or updates the
host to 5.0.x, and gives you the option to migrate some existing host settings
and configuration files, and preserve the existing VMFS datastore. See
“Upgrade or Migrate Hosts Interactively,” on page 113.
Perform a scripted
upgrade or update
You can upgrade or migrate hosts from version 4.x ESXi and ESX and update
version 5.0 ESXi hosts to ESXi 5.0.x by invoking a script, for an efficient,
unattended upgrade. Scripted upgrades and updates provide an efficient
way to deploy multiple hosts. You can use a script to upgrade or update
ESXi from a CD, DVD or USB flash drive, or by PXE-booting the installer.
You can also call a script from an interactive installation. See “Installing,
Upgrading, or Migrating Hosts Using a Script,” on page 114.
vSphere Auto Deploy
Auto Deploy is a new feature in vSphere 5.0. Working with hosts managed
by vCenter Server, Auto Deploy loads the ESXi image directly into the host
memory, rather than installing it on the host hard disk. You cannot use Auto
Deploy to upgrade or migrate version 4.x ESX and ESXi hosts to ESXi 5.0,
because version 4.x ESX and ESXi hosts are deployed by the traditional
method of installing the software on the host hard disk. After a ESXi 5.0 host
is deployed with Auto Deploy, you can use Auto Deploy to upgrade, update,
or apply patches to the host. To do this, you reprovision the host by
rebooting it with a new image profile that contains the ESXi upgrade,
update, or patch, a host configuration profile, and, optionally, third-party
drivers or management agents provided by VMware partners. You can build
custom images by using ESXi Image Builder CLI. See “Using vSphere Auto
Deploy to Reprovision Hosts,” on page 128.
esxcli
You can apply patches to ESXi 5.0 hosts using the esxcli command-line
utility for ESXi. You cannot use esxcli to upgrade ESX/ESXi 4.x hosts to ESXi
5.0.x. This utility requires the vSphere CLI. See “Upgrading Hosts by Using
esxcli Commands,” on page 133.
The esxupdate and vihostupdate utilities are not supported for ESXi 5.0.x upgrades or updates.

Upgrading Hosts That Have Third-Party Custom VIBs
When you upgrade a host that contains custom VIBs, the upgrade displays an error message unless the
same VIBs are included in the upgrade ISO file.
A host can have custom VIBs installed, for example, for third-party drivers or management agents. For
example, ESX/ESXi 4.x hosts can contain Cisco Nexus 1000V VEMs or EMC PowerPath modules. The ESXi
5.0 architecture differs from ESX/ESXi 4.x so that customized third-party software packages (VIBs) cannot be
migrated when you upgrade from ESX/ESXi 4.x to ESXi 5.0. When you upgrade a 4.x host with custom VIBs
that are not in the upgrade ISO, the ESXi installer displays an error message that lists the missing VIBs.
To migrate the third-party customizations as part of the host upgrade, use ESXi Image Builder to create a
custom ESXi ISO image that includes the missing VIBs. For information about using Image Builder to make
a custom ISO, see the information about Using ESXi Image Builder in the vSphere Installation and Setup
documentation.
To upgrade without including the third-party software, you can take one of the following actions.
n
Remove the third-party software. If you are using vSphere Update Manager, select the option to
remove third-party software modules during the remediation process. For information about
upgrading with vSphere Update Manager, see Installing and Administering VMware vSphere Update
Manager.
n
Override the error message during the host upgrade by selecting the Force Migrate option.
CAUTION Using either of these two options might cause the upgraded host to not boot properly, to exhibit
system instability, or to lose functionality. Ensure that your system does not have any critical dependence
on third-party VIBs that requires resolution on first boot and cannot be resolved later. For example, your
system might require custom drivers for NICs that you are booting from.
If you are upgrading a host running ESX/ESXi 4.1 Upgrade 1 or ESX/ESXi 4.0 Upgrade 3, you will see the
error message for the VIBs listed in Table 6-3, even if you have never installed any custom VIBs. If you are
sure that the proper functioning or your system does not depend on those VIBs, you can choose to ignore
the warnings and continue with the upgrade.

Supported Upgrades and Updates to ESXi 5.0.x
You can update an ESXi 5.0 host directly to ESXi 5.0.x., and in most cases, you can migrate or upgrade an
ESX 4.x or ESXi 4.x host directly to ESXi 5.0.x.
The details and level of support for an upgrade or migration from version 4.x ESX and ESXi hosts, and for
an update of version 5.0 ESXi hosts, to ESXi 5.0.x depend on the host and the upgrade or update method
that you use.

Support
3.x ESX and ESXi hosts
Not supported for direct upgrade.
You must upgrade version 3.x ESX and ESXi hosts to ESX
or ESXi version 4.x before you can upgrade them to ESXi
5.0. See the vSphere 4.x upgrade documentation.
Alternatively, you might find it simpler and more cost
effective to do a fresh installation of ESXi 5.0.x
4.x ESX host that was upgraded from ESX 3.x with a
partition layout incompatible with ESXi 5.0.x
Not supported.
The VMFS partition cannot be preserved. Upgrading or
migration is possible only if there is at most one VMFS
partition on the disk that is being upgraded and the VMFS
partition must start after sector 1843200. Perform a fresh
installation. To keep virtual machines, migrate them to a
different system.
4.x ESX or ESXi host, migration or upgrade with vSphere
Update Manager
Supported. See “Using vSphere Update Manager to
Perform Orchestrated Host Upgrades,” on page 99 and
the Installing and Administering VMware vSphere Update
Manager documentation.
4.x ESX or ESXi host, interactive migration or upgrade
Supported. See “Upgrade or Migrate Hosts Interactively,”
on page 113.
The installer wizard offers the choice to upgrade or
perform a fresh installation. If you upgrade, ESX partitions
and configuration files are converted to be compatible with
ESXi.
4.x ESX or ESXi host, scripted upgrade
Supported. See “Installing, Upgrading, or Migrating Hosts
Using a Script,” on page 114.
In the upgrade script, specify the particular disk to
upgrade on the system. If the system cannot be upgraded
correctly because the partition table is incompatible, the
installer displays a warning and does not proceed. In this
case, perform a fresh installation. Upgrading or migration
is possible only if there is at most one VMFS partition on
the disk that is being upgraded and the VMFS partition
must start after sector 1843200.

Scenario for Upgrade, Migration, or Update to ESXi
5.0.x
Support
4.x ESX host on a SAN or SSD
Partially supported.
You can upgrade the host as you would a normal ESX 4.x
host, but no provisions will be made to optimize the
partitions on the disk. To optimize the partition scheme on
the host, perform a fresh installation.
4.x ESX host, missing Service Console .vmdk file,
interactive migration from CD or DVD, scripted migration,
or migration with vSphere Update Manager
Not supported.
The most likely reasons for a missing Service Console are
that the Service Console is corrupted or that the VMFS
volume is not available, which can occur if the VMFS was
installed on a SAN and the LUN is not accessible. In this
case, on the disk selection screen of the installer wizard, if
you select a disk that has an existing ESX 4.x installation,
the wizard prompts you to perform a clean installation.
4.x ESX or ESXi host, asynchronously released driver or
other third-party customizations, interactive migration
from CD or DVD, scripted migration, or migration with
vSphere Update Manager
Supported with ESXi Image Builder CLI.
If a host contains customizations, such as third-party VIBS
or drivers, upgrading with the standard VMware installer
ISO will result in the loss of those customizations, and
possibly an unstable system. Use ESXi Image Builder CLI
to create a customized ESXi installer ISO file that includes
the VIBs or drivers. See the information on Image Builder
in the vSphere Installation and Setup documentation.
5.0 ESXi host
Methods supported for direct update to ESXi 5.0.x are:
n vSphere Update Manager. Supported if you use a
patch baseline, and not an upgrade baseline.
n Interactive update from CD, DVD, or USB drive.
n Scripted update
n Auto Deploy (if the 5.0 ESXi host was deployed using
Auto Deploy).
n esxcli, using profile update option.
Using Manually Assigned IP Addresses for Upgrades and Migrations Performed
with vSphere Update Manager
If you are using vSphere Update Manager to upgrade or migrate a host to ESXi 5.0, you must use manually
assigned IP addresses for the hosts. Manually assigned IP addresses also referred to as static IP addresses.
DHCP IP addresses can cause problems during host upgrades or migrations performed with Update
Manager. If a host loses its DHCP IP address during an upgrade or migration because the lease period
configured on the DHCP server expires, Update Manager loses connectivity to the host. In this case, even if
the host upgrade or migration is successful, Update Manager reports the upgrade or migration as failed,
because it cannot connect to the host. To prevent this scenario, use manually assigned IP addresses for your
hosts.
Media Options for Booting the ESXi Installer
The ESXi installer must be accessible to the system on which you are installing ESXi.
The following boot media are supported for the ESXi installer:
n
Boot from a CD/DVD. See “Download and Burn the ESXi Installer ISO Image to a CD or DVD,” on
page 88.
n
Boot from a USB flash drive. See “Format a USB Flash Drive to Boot the ESXi Installation or Upgrade,”
on page 88.

Unmount the USB flash drive.
umount /usbdisk
11
Unmount the installer ISO image.
umount /esxi_cdrom
The USB flash drive can now boot the ESXi installer.
Create a USB Flash Drive to Store the ESXi Installation Script or Upgrade Script
You can use a USB flash drive to store the ESXi installation script or upgrade script that is used during
scripted installation or upgrade of ESXi.
When multiple USB flash drives are present on the installation machine, the installation software searches
for the installation or upgrade script on all attached USB flash drives.
VMware, Inc.

Chapter 6 Upgrading and Migrating Your Hosts
Create an Installer ISO Image with a Custom Installation or Upgrade Script
You can customize the standard ESXi installer ISO image with your own installation or upgrade script. This
enables you to perform a scripted, unattended installation or upgrade when you boot the resulting installer
ISO image.
See also “About Installation and Upgrade Scripts,” on page 117 and “About the boot.cfg File,” on page 125.
Prerequisites
n
Linux machine.
n
The ESXi ISO image VMware-VMvisor-Installer-5.0.0-XXXXXX.x86_64.iso, where XXXXXX is the build
number of the installer ISO image.
n
Your custom installation or upgrade script, the ks_cust.cfg kickstart file.
Procedure
1
Download the ESXi ISO image from the VMware Web site.
2
Mount the ISO image into a folder:
mount -o loop VMware-VMvisor-Installer-5.0.0-XXXXXX.x86_64.iso /esxi_cdrom_mount
XXXXXX is the ESXi build number for the version that you are installing or upgrading to.
3
Copy the contents of cdrom to another folder:
cp -r /esxi_cdrom_mount /esxi_cdrom
4
Copy the kickstart file to /esxi_cdrom
cp ks_custom.cfg /esxi_cdrom
5
(Optional) Modify the boot.cfg file to specify the location of the installation or upgrade script using the
kernelopt option.
This step makes the installation or upgrade completely automatic, without the need to specify the
kickstart file during the installation or upgrade.
6
Recreate the ISO image:
mkisofs -relaxed-filenames -J -R -o custom_esxi.iso -b isolinux.bin -c boot.cat -no-emul-boot
-boot-load-size 4 -boot-info-table /esxi_cdrom
The ISO image now includes your custom installation or upgrade script.
What to do next
Install ESXi from the ISO image.
PXE Booting the ESXi Installer
You use the preboot execution environment (PXE) to boot a host and launch the ESXi installer from a
network interface.
ESXi 5.0 is distributed in an ISO format that is designed to install to flash memory or to a local hard drive.
You can extract the files and boot using PXE.
PXE uses DHCP and Trivial File Transfer Protocol (TFTP) to boot an operating system over a network.
VMware, Inc.
91
vSphere Upgrade
PXE booting requires some network infrastructure and a machine with a PXE-capable network adapter.
Most machines that are capable of running ESXi have network adapters that are able to PXE boot.
NOTE Ensure that the Auto Deploy server has an IPv4 address. PXE booting is supported only with IPv4.
About the TFTP Server, PXELINUX, and gPXE
Trivial File Transfer Protocol (TFTP) is similar to the FTP service, and is typically used only for network
booting systems or loading firmware on network devices such as routers.
Most Linux distributions include a copy of the tftp-hpa server. If you require a supported solution, purchase
a supported TFTP server from your vendor of choice.
If your TFTP server will run on a Microsoft Windows host, use tftpd32 version 2.11 or later. See
http://tftpd32.jounin.net/. Earlier versions of tftpd32 were incompatible with PXELINUX and gPXE.
You can also acquire a TFTP server from one of the packaged appliances on the VMware Marketplace.
The PXELINUX and gPXE environments allow your target machine to boot the ESXi installer. PXELINUX is
part of the SYSLINUX package, which can be found at
http://www.kernel.org/pub/linux/utils/boot/syslinux/, although many Linux distributions include it. Many
versions of PXELINUX also include gPXE. Some distributions, such as Red Hat Enterprise Linux version 5.3,
include earlier versions of PXELINUX that do not include gPXE.
If you do not use gPXE, you might experience problems while booting the ESXi installer on a heavily loaded
network TFTP is sometimes unreliable for transferring large amounts of data. If you use PXELINUX without
gPXE, the pxelinux.0 binary file, the configuration file, the kernel, and other files are transferred by TFTP. If
you use gPXE, only the gpxelinux.0 binary file and configuration file are transferred by TFTP. With gPXE,
you can use a Web server to transfer the kernel and other files required to boot the ESXi installer.
NOTE VMware tests PXE booting with PXELINUX version 3.86. This is not a statement of limited support.
For support of third-party agents that you use to set up your PXE booting infrastructure, contact the vendor.

Sample DHCP Configuration
To PXE boot the ESXi installer, the DHCP server must send the address of the TFTP server and a pointer to
the pxelinux.0 or gpxelinux.0 directory.
The DHCP server is used by the target machine to obtain an IP address. The DHCP server must be able to
determine whether the target machine is allowed to boot and the location of the PXELINUX binary (which
usually resides on a TFTP server). When the target machine first boots, it broadcasts a packet across the
network requesting this information to boot itself. The DHCP server responds.
CAUTION Do not set up a new DHCP server if your network already has one. If multiple DHCP servers
respond to DHCP requests, machines can obtain incorrect or conflicting IP addresses, or can fail to receive
the proper boot information. Talk to a network administrator before setting up a DHCP server. For support
on configuring DHCP, contact your DHCP server vendor.
Many DHCP servers can PXE boot hosts. If you are using a version of DHCP for Microsoft Windows, see the
DHCP server documentation to determine how to pass the next-server and filename arguments to the
target machine.

When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the
gpxelinux.0 binary file on the TFTP server. The IP address assigned is in the range defined in the subnet
section of the configuration file.
PXELINUX (without gPXE) Example

When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the
pxelinux.0 binary file on the TFTP server. The IP address assigned is in the range defined in the subnet
section of the configuration file.
About PXE Configuration Files
The PXE configuration file defines the menu displayed to the target ESXi host as it boots up and contacts the
TFTP server. You need a PXE configuration file to PXE boot the ESXi installer.
The TFTP server constantly listens for PXE clients on the network. When it detects that a PXE client is
requesting PXE services, it sends the client a network package that contains a boot menu.

VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
Required Files
In the PXE configuration file, you must include paths to the following files:
n
mboot.c32 is the boot loader.
n
boot.cfg is the boot loader configuration file.
See “About the boot.cfg File,” on page 125
File Name for the PXE Configuration File
For the file name of the PXE configuration file, select one of the following options:
n
01-mac_address_of_target_ESXi_host. For example, 01-23-45-67-89-0a-bc
n
The target ESXi host IP address in hexadecimal notation.
n
default
The initial boot file, pxelinux.0 or gpxelinux.0, tries to load a PXE configuration file. It tries with the MAC
address of the target ESXi host, prefixed with its ARP type code, which is 01 for Ethernet. If that attempt
fails, it tries with the hexadecimal notation of target ESXi system IP address. Ultimately, it tries to load a file
named default.
File Location for the PXE Configuration File
Save the file in var/lib/tftpboot/pxelinux.cfg/ on the TFTP server.
For example, you might save the file on the TFTP server at /tftpboot/pxelinux.cfg/01-00-21-5a-ce-40-f6.
The MAC address of the network adapter on the target ESXi host is 00-21-5a-ce-40-f6.

Chapter 6 Upgrading and Migrating Your Hosts
Using Remote Management Applications
Remote management applications allow you to install ESXi on servers that are in remote locations.
Remote management applications supported for installation include HP Integrated Lights-Out (iLO), Dell
Remote Access Card (DRAC), IBM management module (MM), and Remote Supervisor Adapter II (RSA II).
For a list of currently supported server models and remote management firmware versions, see “Supported
Remote Management Server Models and Minimum Firmware Versions,” on page 25. For support on remote
management applications, contact the vendor.
You can use remote management applications to do both interactive and scripted installations of ESXi
remotely.
If you use remote management applications to install ESXi, the virtual CD might encounter corruption
problems with systems or networks operating at peak capacity. If a remote installation from an ISO image
fails, complete the installation from the physical CD media.
Performing the Upgrade or Migration
Several tools are available to upgrade and migrate hosts. You can use different upgrade tools based
depending on the type of host you are upgrading (ESX or ESXi) and whether the hosts are managed by
vCenter Server.
You can migrate or upgrade from version 4.x ESX or ESXi to ESXi 5.0 with the tools and methods described
in “ESXi 5.0.x Upgrade and Update Options,” on page 84.
To upgrade version 3.5 ESX or ESXi to ESXi 5.0, you must first upgrade version 3.5 ESX or ESXi to version
4.x ESX or ESXi. See the VMware vSphere 4.x documentation Web page for information about upgrading
from version 3.5 ESX or ESXi 3.5 to version 4.x ESX or ESXi.
CAUTION If you upgrade hosts managed by vCenter Server, you must upgrade to vCenter Server before you
upgrade ESX or ESXi. If you do not upgrade in the correct order, you can lose data and lose access to your
servers.
Using vSphere Update Manager to Perform Orchestrated Host Upgrades
Orchestrated upgrades allow you to upgrade the objects in your vSphere inventory in a two-step process:
host upgrades, followed by virtual machine upgrades. You can configure the process at the cluster level to
automate more of the process, or you can configure it at the individual host or virtual machine level for
granular control.
For example, you can define a host upgrade baseline to upgrade an ESXi 4.x host to ESXi 5.0, or you can
define a virtual machine upgrade baseline to upgrade the VMware Tools and the virtual machine hardware
to the latest version. Use wizard-based workflows to first schedule host upgrades for an entire cluster and
then schedule a virtual machine upgrade for all the virtual machines.
You cannot use Update Manager to upgrade a host to ESXi 5.0 if the host was previously upgraded from
ESX 3.x to ESX 4.x. Such hosts do not have sufficient free space in the /boot partition to support the Update
Manager upgrade process. This problem also affects some 4.x ESX hosts, even if they were not previously
upgraded from ESX 3.x. Hosts must have more than 350MB of free space in the /boot partition to support
the Update Manager upgrade process. If the host that you are upgrading does not have more than 350MB of
free space in the /boot partition, use a scripted or interactive upgrade instead.
IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot roll back to your version 4.x
ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the
upgrade or migration fails, you can restore your 4.x host.
VMware, Inc.
99
vSphere Upgrade
The wizard workflows prevent erroneous upgrade sequences. For example, the wizard prevents you from
upgrading virtual machine hardware before you upgrade hosts in a cluster.
You can use Distributed Resource Scheduler (DRS) to prevent virtual machine downtime during the
upgrade process.
Update Manager monitors hosts and virtual machines for compliance against your defined upgrade
baselines. Noncompliance appears in detailed reports and in the dashboard view. Update Manager supports
mass remediation.
The following vSphere components are upgraded by Update Manager.
n
ESX and ESXi kernel (vmkernel)
n
Virtual machine hardware
n
VMware Tools
n
Virtual appliances
For components that are not listed here, you can perform the upgrade by using another upgrade method, or,
for third-party components, by using the appropriate third-party tools.
The following topics describe how to use Update Manager to conduct an orchestrated upgrade of your ESXi
hosts.
n
“Configuring Host and Cluster Settings,” on page 100
n
“Perform an Orchestrated Upgrade of Hosts Using vSphere Update Manager,” on page 101
To use Update Manager to conduct an orchestrated upgrade of virtual machines on your hosts, see
“Perform an Orchestrated Upgrade of Virtual Machines with vSphere Update Manager,” on page 151. For
complete documentation of all Update Manager operations, see the vSphere Update Manager Installation and
Administration Guide.
Configuring Host and Cluster Settings
When you update vSphere objects in a cluster with DRS, VMware High Availability (HA), and VMware
Fault Tolerance (FT) enabled, you can choose to temporarily disable VMware Distributed Power
Management (DPM), HA admission control, and FT for the entire cluster. When the update completes,
Update Manager restores these features.
Updates might require that the host enters maintenance mode during remediation. Virtual machines cannot
run when a host is in maintenance mode. To ensure availability, vCenter Server can migrate virtual
machines to other ESX/ESXi hosts within a cluster before the host is put into maintenance mode.
vCenter Server migrates the virtual machines if the cluster is configured for vMotion, and if DRS is enabled.
If a host has no running virtual machines, VMware DPM might put the host in standby mode and interrupt
an Update Manager operation. To make sure that scanning and staging complete successfully,
Update Manager disables VMware DPM during these operations. To ensure successful remediation, you
should allow Update Manager to disable VMware DPM and HA admission control before the remediation
operation. After the operation completes, Update Manager restores VMware DPM and HA admission
control. Update Manager disables HA admission control before staging and remediation but not before
scanning.
If VMware DPM has already put hosts in standby mode, Update Manager powers on the hosts before
scanning, staging, and remediation. After the scanning, staging, or remediation is complete,
Update Manager turns on VMware DPM and HA admission control and lets VMware DPM put hosts into
standby mode, if needed. Update Manager does not remediate powered off hosts.
If hosts are put into standby mode and VMware DPM is manually disabled for a reason, Update Manager
does not remediate or power on the hosts.
100
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
Within a cluster, you should select to temporarily disable HA admission control to allow vMotion to
proceed, in order to prevent downtime of the machines on the hosts you remediate. After the remediation of
the entire cluster, Update Manager restores HA admission control settings.
If FT is turned on for any of the virtual machines on hosts within a cluster, you should select to temporarily
turn off FT before performing any Update Manager operations on the cluster. If FT is turned on for any of
the virtual machines on a host, Update Manager does not remediate that host. You should remediate all
hosts in a cluster with the same updates, so that FT can be re-enabled after the remediation, because a
primary virtual machine and a secondary virtual machine cannot reside on hosts of different ESX/ESXi
version and patch level.
Perform an Orchestrated Upgrade of Hosts Using vSphere Update Manager
You can use Update Manager to perform orchestrated upgrades of the ESX/ESXi hosts in your vSphere
inventory by using a single upgrade baseline, or by using a baseline group.
This workflow describes the overall process to perform an orchestrated upgrade of the hosts in your
vSphere inventory. Update Manager 5.0 supports host upgrades to ESXi 5.0 for hosts that are running
ESX/ESXi 4.x.
You can perform orchestrated upgrades of hosts at the folder, cluster, or datacenter level.
NOTE The last two steps in this procedure are alternatives. Choose one or the other.

1
Configure Host Maintenance Mode Settings on page 102
ESX/ESXi host updates might require that the host enters maintenance mode before they can be
applied. Update Manager puts the ESX/ESXi hosts in maintenance mode before applying these
updates. You can configure how Update Manager responds if the host fails to enter maintenance
mode.
2
Configure Cluster Settings on page 103
For ESX/ESXi hosts in a cluster, the remediation process can run either in a sequence or in parallel.
Certain features might cause remediation failure. If you have VMware DPM, HA admission control, or
Fault Tolerance enabled, you should temporarily disable these features to make sure that the
remediation is successful.
3
Enable Remediation of PXE Booted ESXi 5.0 Hosts on page 104
You can configure Update Manager to let other software initiate remediation of PXE booted ESXi 5.x
hosts. The remediation installs patches and software modules on the hosts, but typically the host
updates are lost after a reboot.
4
Import Host Upgrade Images and Create Host Upgrade Baselines on page 105
You can create upgrade baselines for ESX/ESXi hosts with ESXi 5.x images that you import to the
Update Manager repository.

Create a Host Baseline Group on page 106
You can combine one host upgrade baseline with multiple patch or extension baselines, or combine
multiple patch and extension baselines in a baseline group.
6
Attach Baselines and Baseline Groups to Objects on page 107
To view compliance information and remediate objects in the inventory against specific baselines and
baseline groups, you must first attach existing baselines and baseline groups to these objects.
7
Manually Initiate a Scan of ESX/ESXi Hosts on page 107
Before remediation, you should scan the vSphere objects against the attached baselines and baseline
groups. To run a scan of hosts in the vSphere inventory immediately, initiate a scan manually.
8
View Compliance Information for vSphere Objects on page 108
You can review compliance information for the virtual machines, virtual appliances, and hosts against
baselines and baseline groups that you attach.
9
Remediate Hosts Against an Upgrade Baseline on page 108
You can remediate ESX/ESXi hosts against a single attached upgrade baseline at a time. You can
upgrade or migrate all hosts in your vSphere inventory by using a single upgrade baseline containing
an ESXi 5.0 image.
10
Remediate Hosts Against Baseline Groups on page 111
You can remediate hosts against attached groups of upgrade, patch, and extension baselines. Baseline
groups might contain multiple patch and extension baselines, or an upgrade baseline combined with
multiple patch and extension baselines.
Configure Host Maintenance Mode Settings
ESX/ESXi host updates might require that the host enters maintenance mode before they can be applied.
Update Manager puts the ESX/ESXi hosts in maintenance mode before applying these updates. You can
configure how Update Manager responds if the host fails to enter maintenance mode.
For hosts in a container different from a cluster or for individual hosts, migration of the virtual machines
with vMotion cannot be performed. If vCenter Server cannot migrate the virtual machines to another host,
you can configure how Update Manager responds.
Prerequisites
Connect the vSphere Client to a vCenter Server system with which Update Manager is registered, and on
the Home page, click Update Manager under Solutions and Applications. If your vCenter Server system is
part of a connected group in vCenter Linked Mode, you must specify the Update Manager instance to use,

If a host fails to enter maintenance mode before remediation, Update Manager waits for the retry delay
period and retries putting the host into maintenance mode as many times as you indicate in Number of
retries field.
4
(Optional) Select Temporarily disable any removable media devices that might prevent a host from
entering maintenance mode.
Update Manager does not remediate hosts on which virtual machines have connected CD/DVD or
floppy drives. All removable media drives that are connected to the virtual machines on a host might
prevent the host from entering maintenance mode and interrupt remediation.
After remediation, Update Manager reconnects the removable media devices if they are still available.
5
Click Apply.
These settings become the default failure response settings. You can specify different settings when you
configure individual remediation tasks.
Configure Cluster Settings
For ESX/ESXi hosts in a cluster, the remediation process can run either in a sequence or in parallel. Certain
features might cause remediation failure. If you have VMware DPM, HA admission control, or Fault
Tolerance enabled, you should temporarily disable these features to make sure that the remediation is
successful.
NOTE Remediating hosts in parallel can improve performance significantly by reducing the time required
for cluster remediation. Update Manager remediates hosts in parallel without disrupting the cluster
resource constraints set by DRS.

Select the check boxes for features that you want to disable or enable.
Option
Description
Distributed Power Management
(DPM)
VMware DPM monitors the resource use of the running virtual machines
in the cluster. If sufficient excess capacity exists, VMware DPM
recommends moving virtual machines to other hosts in the cluster and
placing the original host into standby mode to conserve power. If the
capacity is insufficient, VMware DPM might recommend returning
standby hosts to a powered-on state.
If you do not choose to disable DPM, Update Manager skips the cluster on
which VMware DPM is enabled. If you choose to temporarily disable
VMware DPM, Update Manager disables DPM on the cluster, remediates
the hosts in the cluster, and re-enables VMware DPM after remediation is
complete.
High Availability (HA) admission
control
Admission control is a policy used by VMware HA to ensure failover
capacity within a cluster. If HA admission control is enabled during
remediation, the virtual machines within a cluster might not migrate with
vMotion.
If you do not choose to disable HA admission control, Update Manager
skips the cluster on which HA admission control is enabled. If you choose
to temporarily disable HA admission control, Update Manager disables
HA admission control, remediates the cluster, and re-enables HA
admission control after remediation is complete.
Fault Tolerance (FT)
FT provides continuous availability for virtual machines by automatically
creating and maintaining a secondary virtual machine that is identical to
the primary virtual machine. If you do not choose to turn off FT for the
virtual machines on a host, Update Manager does not remediate that host.
Enable parallel remediation for
hosts in cluster
Update Manager can remediate hosts in clusters in a parallel manner.
Update Manager continuously evaluates the maximum number of hosts it
can remediate in parallel without disrupting DRS settings. If you do not
select the option, Update Manager remediates the hosts in a cluster
sequentially.
Migrate powered off and suspended
virtual machines to other hosts in
the cluster, if a host must enter
maintenance mode
Update Manager migrates the suspended and powered off virtual
machines from hosts that must enter maintenance mode to other hosts in
the cluster. You can select to power off or suspend virtual machines before
remediation in the Maintenance Mode Settings pane.
Click Apply.
These settings become the default failure response settings. You can specify different settings when you
configure individual remediation tasks.
Enable Remediation of PXE Booted ESXi 5.0 Hosts
You can configure Update Manager to let other software initiate remediation of PXE booted ESXi 5.x hosts.
The remediation installs patches and software modules on the hosts, but typically the host updates are lost
after a reboot.
The global setting in the Update Manager Configuration tab enables solutions such as ESX Agent Manager
or Cisco Nexus 1000V to initiate remediation of PXE booted ESXi 5.x hosts. In contrast, the Enable patch
remediation of powered on PXE booted ESXi hosts setting in the Remediate wizard enables Update
Manager to patch PXE booted hosts.
To retain updates on stateless hosts after a reboot, use a PXE boot image that contains the updates. You can
update the PXE boot image before applying the updates with Update Manager, so that the updates are not
lost because of a reboot. For more information about creating custom ESXi images, see Image Builder
Administration. Update Manager itself does not reboot the hosts because it does not install updates requiring
a reboot on PXE booted ESXi 5.0 hosts.

Attach Baselines and Baseline Groups to Objects
To view compliance information and remediate objects in the inventory against specific baselines and
baseline groups, you must first attach existing baselines and baseline groups to these objects.
You can attach baselines and baseline groups to objects from the Update Manager Client Compliance view.
Although you can attach baselines and baseline groups to individual objects, a more efficient method is to
attach them to container objects, such as folders, vApps, clusters, and datacenters. Individual vSphere
objects inherit baselines attached to the parent container object. Removing an object from a container
removes the inherited baselines from the object.
If your vCenter Server system is part of a connected group in vCenter Linked Mode, you can attach
baselines and baseline groups to objects managed by the vCenter Server system with which
Update Manager is registered. Baselines and baseline groups you attach are specific for the Update Manager
instance that is registered with the vCenter Server system.
Prerequisites
Ensure that you have the Attach Baseline privilege.
Procedure
1
Connect the vSphere Client to a vCenter Server system with which Update Manager is registered and
select Home > Inventory in the navigation bar.
2
Select the type of object that you want to attach the baseline to.
For example, Hosts and Clusters or VMs and Templates.
3

Remediate Hosts Against an Upgrade Baseline
You can remediate ESX/ESXi hosts against a single attached upgrade baseline at a time. You can upgrade or
migrate all hosts in your vSphere inventory by using a single upgrade baseline containing an ESXi 5.0
image.
NOTE Alternatively, you can upgrade hosts by using a baseline group. See “Remediate Hosts Against
Baseline Groups,” on page 111.
Update Manager 5.0 supports only upgrade from ESXi 4.x to ESXi 5.x and migration from ESX 4.x to
ESXi 5.x. You cannot use Update Manager to upgrade a host to ESXi 5.0 if the host was upgraded from ESX
3.x to ESX 4.x. Such hosts do not have sufficient free space in the /boot partition to support the Update
Manager upgrade process. Use a scripted or interactive upgrade instead.
To upgrade or migrate hosts, use the ESXi installer image distributed by VMware with the name format
VMware-VMvisor-Installer-5.0.0-build_number.x86_64.iso or a custom image created by using Image
Builder.
NOTE In case of an unsuccessful upgrade or migration from ESX/ESXi 4.x to ESXi 5.x, you cannot roll back
to your previous ESX/ESXi 4.x instance.

If FT is turned on for any of the virtual machines on a host,
Update Manager does not remediate that host.
For FT to be enabled, the hosts on which the Primary and Secondary
virtual machines run must be of the same version and must have the same
patches installed. If you apply different patches to these hosts, FT cannot
be re-enabled.
Enable parallel remediation for the
hosts in the selected clusters.
Remediate hosts in clusters in a parallel manner. If the setting is not
selected, Update Manager remediates the hosts in a cluster sequentially.
By default, Update Manager continuously evaluates the maximum number
of hosts it can remediate concurrently without disrupting DRS settings.
You can limit the number of concurrently remediated hosts to a specific
number.
NOTE Update Manager remediates concurrently only the hosts on which
virtual machines are powered off or suspended. You can choose to power
off or suspend virtual machines from the Power State menu in the
Maintenance Mode Settings pane on the Host Remediation Options page.
Migrate powered off and suspended
virtual machines to other hosts in
the cluster, if a host must enter
maintenance mode.
Update Manager migrates the suspended and powered off virtual
machines from hosts that must enter maintenance mode to other hosts in
the cluster. You can choose to power off or suspend virtual machines
before remediation in the Maintenance Mode Settings pane.

Upgrade or Migrate Hosts Interactively
You can boot the ESXi installer from a CD, DVD, or USB flash drive to upgrade ESX/ESXi 4.x hosts to ESXi
5.0.
IMPORTANT If you are performing a fresh ESXi installation, see the vSphere Installation and Setup
documentation. The instructions in this vSphere Upgrade documentation are for an upgrade or migration of
ESXi or ESX.
Before upgrading, consider disconnecting your network storage. This action decreases the time it takes the
installer to search for available disk drives. When you disconnect network storage, any files on the
disconnected disks are unavailable at installation. Do not disconnect a LUN that contains an existing ESX or
ESXi installation. Do not disconnect a VMFS datastore that contains the Service Console of an existing ESX
installation. These actions can affect the outcome of the installation.
IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot roll back to your version 4.x
ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the
upgrade or migration fails, you can restore your 4.x host.
Prerequisites
n
You must have the ESXi installer ISO in one of the following locations.
n
On CD or DVD. If you do not have the installation CD/DVD, you can create one. See “Download
and Burn the ESXi Installer ISO Image to a CD or DVD,” on page 88
n
On a USB flash drive. See “Format a USB Flash Drive to Boot the ESXi Installation or Upgrade,” on
page 88
NOTE You can also PXE boot the ESXi installer to launch an interactive installation or a scripted
installation. See “PXE Booting the ESXi Installer,” on page 91.

vSphere Upgrade
n
Verify that the server hardware clock is set to UTC. This setting is in the system BIOS.
n
ESXi Embedded must not be on the host. ESXi Installable and ESXi Embedded cannot exist on the same
host.
Procedure
1
Insert the ESXi installer CD/DVD into the CD/DVD-ROM drive, or attach the Installer USB flash drive
and restart the machine.
2
Set the BIOS to boot from the CD-ROM device or the USB flash drive.
See your hardware vendor documentation for information on changing boot order.
3
In the Select a Disk panel, select the drive on which to install ESXi and press Enter.
Press F1 for information about the selected disk.
NOTE Do not rely on the disk order in the list to select a disk. The disk order is determined by the
BIOS. On systems where drives are continuously being added and removed, they might be out of order.
4
If the installer finds an existing ESX or ESXi installation and VMFS datastore you can choose from the
following options:
n
Upgrade ESXi, preserve VMFS datastore
n
Install ESXi, preserve VMFS datastore
n
Install ESXi, overwrite VMFS datastore
If an existing VMFS datastore cannot be preserved, you can choose only to install ESXi and overwrite
the existing VMFS datastore, or to cancel the installation. If you choose to overwrite the existing VMFS
datastore, back up the datastore first.
If the existing ESX or ESXi installation contains custom VIBs that are not included in the ESXi installer
ISO, the option Upgrade ESXi, preserve VMFS datastore is replaced with Force Migrate ESXi,
preserve VMFS datastore.
CAUTION Using the Force Migrate option might cause the upgraded host to not boot properly, to
exhibit system instability, or to lose functionality. See “Upgrading Hosts That Have Third-Party
Custom VIBs,” on page 85.
5
Press F11 to confirm and start the upgrade.
6
When the upgrade is complete, remove the installation CD/DVD or USB flash drive.
7
Press Enter to reboot the host.
8
Set the first boot device to be the drive on which you upgraded ESXi in Step 3.
If an existing VMFS datastore cannot be preserved, you can choose only to install ESXi and overwrite
the existing VMFS datastore, or to cancel the installation. If you choose to overwrite the existing VMFS
datastore, back up the datastore first.
See your hardware vendor documentation for information on changing boot order.
Installing, Upgrading, or Migrating Hosts Using a Script
You can quickly deploy ESXi hosts using scripted, unattended installations or upgrades. Scripted
installations, upgrades, or migrations provide an efficient way to deploy multiple hosts.
The installation or upgrade script contains the installation settings for ESXi. You can apply the script to all
hosts that you want to have a similar configuration.
114
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
For a scripted installation, upgrade, or migration, you must use the supported commands to create a script.
and edit the script to change settings that are unique for each host.
The installation or upgrade script can reside in one of the following locations:
n
FTP
n
HTTP/HTTPS
n
NFS
n
USB flash drive
n
CDROM
Enter Boot Options to Start an Installation or Upgrade Script
You can start an installation or upgrade script by typing boot command-line options at the boot command
line.
At boot time you might need to specify options to access the kickstart file. You can enter boot options by
pressing Shift+O in the boot loader. For a PXE boot installation, you can pass options through the
kernelopts line of the boot.cfg file. See “About the boot.cfg File,” on page 125 and “PXE Booting the ESXi
Installer,” on page 91.
A ks=... option must be given, to specify the location of the installation script. Otherwise, a scripted
installation or upgrade will not start. If ks=... is omitted, the text installer will proceed.
Supported boot options are listed in “Boot Options,” on page 116.
IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot roll back to your version 4.x
ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the
upgrade or migration fails, you can restore your 4.x host.

The command section of the script contains the ESXi installation options. This section is required and must
appear first in the script.
Locations Supported for Installation or Upgrade Scripts
In scripted installations and upgrades, the ESXi installer can access the installation or upgrade script, also
called the kickstart file, from several locations.
The following locations are supported for the installation or upgrade script:
n
CD/DVD. See “Create an Installer ISO Image with a Custom Installation or Upgrade Script,” on
page 91.
n

ks=http://XXX.XXX.XXX.XXX/kickstart/KS.CFG is the path to the ESXi installation script, where
XXX.XXX.XXX.XXX is the IP address of the machine where the script resides. See “About Installation and
Upgrade Scripts,” on page 117.
To start an installation script from an interactive installation, you enter the ks= option manually. See “Enter
Boot Options to Start an Installation or Upgrade Script,” on page 115.
Installation and Upgrade Script Commands
To modify the default installation or upgrade script or to create your own script, use supported commands.
Use supported commands in the installation script, which you specify with a boot command when you boot
the installer.
To determine which disk to install or upgrade ESXi on, the installation script requires one of the following
commands: install, upgrade, or installorupgrade. The install command creates the default partitions,
including a VMFS datastore that occupies all available space after the other partitions are created. The
install command replaces the autopart command that was used for scripted ESXi 4.1 installations.
accepteula or vmaccepteula (required)
Accepts the ESXi license agreement. This command functions as it did in ESXi 4.1.
clearpart (optional)
Compared to kickstart, the behavior of the ESXi clearpart command is different. Carefully edit the
clearpart command in your existing scripts.

Differences Between ESXi 4.x and ESXi 5.0 Scripted Installation and Upgrade Commands
Before you perform a scripted ESXi installation or upgrade, if you are familiar with ESXi version 4.x scripted
installation, note the differences between ESXi 4.x and ESXi 5.0 scripted installation and upgrade
commands.
In ESXi 5.0, because the installation image is loaded directly into the host RAM when the host boots, you do
not need to include the location of the installation media in the installation script.
ESXi 5.0 supports scripted upgrades in addition to scripted installation.
Command differences are noted in the following summary.

NOTE When you use a scripted upgrade to upgrade from ESX 4.x to ESXi 5.0, the MPX and VML disk
names change, which might cause the upgrade to fail. To avoid this problem, use Network Address
Authority Identifiers (NAA IDs) for the disk device instead of MPX and VML disk names.
About the boot.cfg File
The boot loader configuration file boot.cfg specifies the kernel, the kernel options, and the boot modules
that the mboot.c32 boot loader uses in an ESXi installation.
The boot.cfg file is provided in the ESXi installer. You can modify the kernelopt line of the boot.cfg file to
specify the location of an installation script or to pass other boot options.
The boot.cfg file has the following syntax:
# boot.cfg -- mboot configuration file
#
# Any line preceded with '#' is a comment.
title=STRING
kernel=FILEPATH
kernelopt=STRING
modules=FILEPATH1 --- FILEPATH2... --- FILEPATHn
# Any other line must remain unchanged.
The commands in boot.cfg configure the boot loader.

Install, Upgrade, or Migrate ESXi from a CD or DVD Using a Script
You can install, upgrade, or migrate ESXi from a CD/DVD drive using a script that specifies the installation
or upgrade options.
You can start the installation or upgrade script by entering a boot option when you start the host. You can
also create an installer ISO image that includes the installation script. With an installer ISO image, you can
perform a scripted, unattended installation when you boot the resulting installer ISO image. See “Create an
Installer ISO Image with a Custom Installation or Upgrade Script,” on page 91.
IMPORTANT After you upgrade or migrate your host to ESXi 5.0, you cannot roll back to your version 4.x
ESX or ESXi software. Back up your host before you perform an upgrade or migration, so that, if the
upgrade or migration fails, you can restore your 4.x host.

For information about using Auto Deploy to perform a scripted upgrade by PXE booting, see “Using
vSphere Auto Deploy to Reprovision Hosts,” on page 128.
Using vSphere Auto Deploy to Reprovision Hosts
If a host was deployed using vSphere Auto Deploy, you can use Auto Deploy to reprovision the host with a
new image profile that contains an ESXi upgrade. You can use vSphere ESXi Image Builder PowerCLI to
create and manage image profiles.
These instructions assume that you are reprovisioning a host that has already been provisioned with Auto
Deploy. Provisioning a host that has never been provisioned with Auto Deploy differs from the process
described here to upgrade a host. For information about using vSphere Auto Deploy and ESXi Image
Builder PowerCLI, see the information about using vSphere Auto Deploy and vSphere ESXi Image Builder
CLI in the vSphere Installation and Setup documentation.
Reprovisioning Hosts
vSphere Auto Deploy supports multiple reprovisioning options. You can perform a simple reboot or
reprovision with a different image or a different host profile.
A first boot using Auto Deploy requires that you set up your environment and add rules to the rule set. See
the topic "Preparing for vSphere Auto Deploy" in the vSphere installation and Setup documentation.
The following reprovisioning operations are available.
128
n
Simple reboot.
n
Reboot of hosts for which the user answered questions during the boot operation.

Reprovision with a different image profile.
n
Reprovision with a different host profile.
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
Reprovision Hosts with Simple Reboot Operations
A simple reboot of a host that is provisioned with Auto Deploy requires only that all prerequisites are still
met. The process uses the previously assigned image profile, host profile, and vCenter Server location.
Setup includes DHCP server setup, writing rules, and making an image available to the Auto Deploy
infrastructure.
Prerequisites
Make sure the setup you performed during the first boot operation is in place.
Procedure
1
Check that the image profile and host profile for the host are still available, and that the host has the
identifying information (asset tag, IP address) it had during previous boot operations.
2
Place the host in maintenance mode.
3
Host Type
Action
Host is part of a DRS cluster
VMware DRS migrates virtual machines to appropriate hosts when you
place the host in maintenance mode.
Host is not part of a DRS cluster
You must migrate all virtual machines to different hosts and place each
host in maintenance mode.
In the vSphere Client, right-click the host and choose Reboot.
The host shuts down. When the host reboots, it uses the image profile that the Auto Deploy server provides.
The Auto Deploy server also applies the host profile stored on the vCenter Server system.
Reprovision a Host with a New Image Profile
You can reprovision the host with a new image profile, host profile, or vCenter Server location by changing
the rule for the host and performing a test and repair operation.
Several options for reprovisioning hosts exist.
n
If the VIBs that you want to use support live update, you can use an esxcli software vib command. In
that case, you must also update the rule set to use an image profile that includes the new VIBs upon
reboot.
n
During testing, you can to apply an image profile to an individual host with the Apply-EsxImageProfile
cmdlet and reboot the host so the change takes effect. The Apply-EsxImageProfile cmdlet updates the
association between the host and the image profile but does not install VIBs on the host.
n
In all other cases, use this procedure.
Prerequisites
n
Create the image profile you want boot the host with. Use the Image Builder PowerCLI. See "Using
vSphere ESXi Image Builder CLI" in the vSphere Installation and Setup documentation.
n
Make sure that the setup that you performed during the first boot operation is in place.

Procedure
1
At the PowerShell prompt, run the Connect-VIServer PowerCLI cmdlet to connect to the vCenter Server
system that Auto Deploy is registered with.
Connect-VIServer myVCServer
The cmdlet might return a server certificate warning. In a production environment, make sure no server
certificate warnings result. In a development environment, you can ignore the warning.
2
Determine the location of a public software depot that contains the image profile that you want to use,
or define a custom image profile with the Image Builder PowerCLI.
3

Run Copy-DeployRule and specify the ReplaceItem parameter to change the rule that assigns an image
profile to hosts.
The following cmdlet replaces the current image profile that the rule assigns to the host with the
my_new_imageprofile profile. After the cmdlet completes, myrule assigns the new image profile to hosts.
The old version of myrule is renamed and hidden.
Copy-DeployRule myrule -ReplaceItem my_new_imageprofile
5
Test and repair rule compliance for each host that you want to deploy the image to.
See “Test and Repair Rule Compliance,” on page 132.
When you reboot hosts after compliance repair, Auto Deploy provisions the hosts with the new image
profile.
Applying a Host Profile to Prompt for User Input
If a host required user input during a previous boot, the answers are saved with the vCenter Server in an
answer file. If you want to prompt the user for new information, you reapply the host profile.
Prerequisites
Attach a host profile that prompts for user input to the host.
Procedure

In the vSphere Client, choose Host Profiles > Apply Profile and choose the host profile that requires
user input when prompted.
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
3
When prompted, provide the user input.
You can now direct the host to exit maintenance mode.
The user input information is saved in an answer file. The next time you boot, the answer file information is
applied to the host. One answer file per host is available.
Assign a Host Profile to Hosts
Auto Deploy can assign a host profile to one or more hosts. The host profile might include information
about storage configuration, network configuration, or other characteristics of the host. If you add a host to a
cluster, that cluster's host profile is used.
The following procedure explains how to write a rule that assigns a host profile to hosts. To assign the host
profiles to hosts already provisioned with Auto Deploy, you must also perform a test and repair cycle. See
“Test and Repair Rule Compliance,” on page 132.
In many cases, you assign a host to a cluster instead of specifying a host profile explicitly. The host uses the
host profile of the cluster.
Prerequisites
n
Install vSphere PowerCLI and all prerequisite software.
n
Export the host profile that you want to use.
n
If you encounter problems running PowerCLI cmdlets, consider changing the execution policy. See the
information about using Auto Deploy Cmdlets in the vSphere Installation and Setup documentation.
Procedure
1
Run the Connect-VIServer PowerCLI cmdlet to connect to the vCenter Server system that Auto Deploy
is registered with.
Connect-VIServer 192.XXX.X.XX
The cmdlet might return a server certificate warning. In a production environment, make sure no server
certificate warnings result. In a development environment, you can ignore the warning.
2
In the vSphere Client, select View > Management > Host Profiles to display the Host Profiles panel and
export the host profile that you want to use from there.
3
Find the name of the host profile by running Get-VMhostProfile, passing in the server on which the
host profile is located.
4
At the PowerCLI prompt, define a rule in which hosts with certain attributes, for example a range of IP
addresses, are assigned to the host profile.
New-DeployRule -Name "testrule2" -Item my_host_profile -Pattern "vendor=Acme,Zven",
"ipv4=192.XXX.1.10-192.XXX.1.20"
The specified item is assigned to all hosts with the specified attributes. This example specifies a rule
named testrule2. The rule assigns the specified host profile my_host_profile to all hosts with an IP
address inside the specified range and with a manufacturer of Acme or Zven.
5
Add the rule to the rule set.
Add-DeployRule testrule2
By default, the working rule set becomes the active rule set, and any changes to the rule set become
active when you add a rule. If you use the NoActivate parameter, the working rule set does not become
the active rule set.

What to do next
n
Upgrade existing hosts to use the new host profile by performing compliance test and repair operations
on those hosts. See “Test and Repair Rule Compliance,” on page 132.
n
Turn on unprovisioned hosts to provision them with the host profile.
Test and Repair Rule Compliance
When you add a rule to the Auto Deploy rule set or make changes to one or more rules, hosts are not
updated automatically. Auto Deploy applies the new rules only when you test their rule compliance and
perform remediation.
This task assumes that your infrastructure includes one or more ESXi hosts provisioned with Auto Deploy,
and that the host on which you installed VMware PowerCLI can access those ESXi hosts.
Prerequisites
n
Install VMware PowerCLI and all prerequisite software.
n
If you encounter problems running PowerCLI cmdlets, consider changing the execution policy. See the
information about using Auto Deploy Cmdlets in the vSphere Installation and Setup documentation.
Procedure
1
Use PowerCLI to check which Auto Deploy rules are currently available.
Get-DeployRule
The system returns the rules and the associated items and patterns.
2
Make a change to one of the available rules, for example, you might change the image profile and the
name of the rule.
Copy-DeployRule -DeployRule testrule -ReplaceItem MyNewProfile
You cannot edit a rule already added to a rule set. Instead, you copy the rule and replace the item or
pattern you want to change.
3
Verify that the host that you want to test rule set compliance for is accessible.
Get-VMHost -Name MyEsxi42
4
Run the cmdlet that tests rule set compliance for the host, and bind the return value to a variable for
later use.
$tr = Test-DeployRuleSetCompliance MyEsxi42
5
Examine the differences between what is in the rule set and what the host is currently using.
$tr.itemlist
The system returns a table of current and expected items.
CurrentItem
----------My Profile 25
6
ExpectedItem
-----------MyProfileUpdate
Remediate the host to use the revised rule set the next time you boot the host.
Repair-DeployRuleSetCompliance $tr
What to do next
If the rule you changed specified the inventory location, the change takes effect when you repair
compliance. For all other changes, boot your host to have Auto Deploy apply the new rule and to achieve
compliance between the rule set and the host.

Chapter 6 Upgrading and Migrating Your Hosts
Upgrading Hosts by Using esxcli Commands
Using the vSphere CLI, you can patch ESXi 5.0 hosts.
You cannot use esxcli commands to upgrade version 4.x ESX or ESXi hosts to ESXi 5.0. To upgrade version
4.x ESX or ESXi hosts to ESXi 5.0, use vSphere Update Manager, or perform an interactive or scripted
upgrade.
To use esxcli vCLI commands, you must install vSphere CLI (vCLI). For more information about installing
and using the vSphere CLI, see the following documents:
n
Getting Started with vSphere Command-Line Interfaces
n
vSphere Command-Line Interface Concepts and Examples
n
vSphere Command-Line Interface Reference is a reference to vicfg- and related vCLI commands.
NOTE If you press Ctrl+C while an esxcli command is running, the command-line interface exits to a new
prompt without displaying a message. However, the command continues to run to completion.
For ESXi hosts deployed with vSphere Auto Deploy, the tools VIB must be part of the base booting image
used for the initial Auto Deploy installation. The tools VIB cannot be added separately later.
VIBs, Image Profiles, and Software Depots
Upgrading ESXi with esxcli commands requires an understanding of VIBs, image profiles, and software
depots.
The following technical terms are used throughout the vSphere documentation set in discussions of
installation and upgrade tasks.
VIB
A VIB is an ESXi software package. VMware and its partners package
solutions, drivers, CIM providers, and applications that extend the ESXi
platform as VIBs. VIBs are available in software depots. You can use VIBs to
create and customize ISO images or to upgrade ESXi hosts by installing VIBs
asynchronously onto the hosts.
Image Profile
An image profile defines an ESXi image and consists of VIBs. An image
profile always includes a base VIB, and might include more VIBs. You
examine and define an image profile using the Image Builder PowerCLI.
Software Depot
A software depot is a collection of VIBs and image profiles. The software
depot is a hierarchy of files and folders and can be available through an
HTTP URL (online depot) or a ZIP file (offline depot). VMware and VMware
partners make depots available. Companies with large VMware installations
might create internal depots to provision ESXi hosts with vSphere Auto
Deploy, or to export an ISO for ESXi installation.
Understanding Acceptance Levels for VIBS and Hosts
Each VIB is released with an acceptance level that cannot be changed. The host acceptance level determines
which VIBs can be installed to a host.
The acceptance level applies to individual VIBs installed by using the esxcli software vib install and
esxcli software vib update commands, to VIBs installed using vSphere Update Manager, and to VIBs in
image profiles.
VMware, Inc.
133
vSphere Upgrade
The acceptance level of all VIBs on a host must be at least as high as the host acceptance level. For example,
if the host acceptance level is VMwareAccepted, you can install VIBs with acceptance levels of
VMwareCertified and VMwareAccepted, but you cannot install VIBs with acceptance levels of
PartnerSupported or CommunitySupported. To install a VIB with a less restrictive acceptance level than that
of the host, you can change the acceptance level of the host by using the vSphere Client or by running
esxcli software acceptance commands.
Setting host acceptance levels is a best practice that allows you to specify which VIBs can be installed on a
host and used with an image profile, and the level of support you can expect for a VIB. For example, a
CommunitySupported VIB might not be recommended for an ESXi server in a production environment.
VMware supports the following acceptance levels.
VMwareCertified
The VMwareCertified acceptance level has the most stringent requirements.
VIBs with this level go through thorough testing fully equivalent to VMware
in-house Quality Assurance testing for the same technology. Today, only
IOVP drivers are published at this level. VMware takes support calls for VIBs
with this acceptance level.
VMwareAccepted
VIBs with this acceptance level go through verification testing, but the tests
do not fully test every function of the software. The partner runs the tests
and VMware verifies the result. Today, CIM providers and PSA plugins are
among the VIBs published at this level. VMware directs support calls for
VIBs with this acceptance level to the partner's support organization.
PartnerSupported
VIBs with the PartnerSupported acceptance level are published by a partner
that VMware trusts. The partner performs all testing. VMware does not
verify the results. This level is used for a new or nonmainstream technology
that partners want to enable for VMware systems. Today, driver VIB
technologies such as Infiniband, ATAoE, and SSD are at this level with
nonstandard hardware drivers. VMware directs support calls for VIBs with
this acceptance level to the partner's support organization.
CommunitySupported
The Community Supported acceptance level is for VIBs created by
individuals or companies outside of VMware partner programs. VIBs at this
level have not gone through any VMware-approved testing program and are
not supported by VMware Technical Support or by a VMware partner.

Match a Host Acceptance Level with an Update Acceptance Level
You can change the host acceptance level to match the acceptance level for a VIB or image profile that you
want to install. The acceptance level of all VIBs on a host must be at least as high as the host acceptance
level.
Use this procedure to determine the acceptance levels of the host and the VIB or image profile to install, and
to change the acceptance level of the host, if necessary for the update.

(Optional) If the acceptance level of the VIB is more restrictive than the acceptance level of the host,
change the acceptance level of the host.
esxcli --server=server_name software acceptance set --level=acceptance_level
The acceptance_level can be VMwareCertified, VMwareAccepted, PartnerSupported, or
CommunitySupported. The values for acceptance_level are case-sensitive.
NOTE You can use the --force option for the esxcli software vib or esxcli software profile
command to add a VIB or image profile with a lower acceptance level than the host. A warning will
appear. Because your setup is no longer consistent, the warning is repeated when you install VIBs,
remove VIBs, and perform certain other operations on the host.
Determine Whether an Update Requires the Host to Be in Maintenance Mode or to
Be Rebooted
VIBs that you can install with live install do not require the host to be rebooted, but might require the host
to be placed in maintenance mode. Other VIBs and profiles might require the host to be rebooted after the
installation or update.
When you specify a target server by using --server=server_name in the procedure, the specified server
prompts you for a user name and password. Other connection options, such as a configuration file or
session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line
Interfaces, or run esxcli --help at the vCLI command prompt.

Procedure
1
Check whether the VIB or image profile that you want to install requires the host to be placed in
maintenance mode or to be rebooted after the installation or update.
Run one of the following commands.
2
Option
Description
Check the VIB
esxcli --server=server_name software sources vib get -v

Check the VIBs in a depot
esxcli --server=server_name software sources vib get -depot=depot_name
Check the image profile in a depot
esxcli --server=server_name software sources profile get -depot=depot_name
Review the return values.
The return values, which are read from the VIB metadata, indicate whether the host must be in
maintenance mode before installing the VIB or image profile, and whether installing the VIB or profile
requires the host to be rebooted.
NOTE vSphere Update Manager relies on the esxupdate/esxcli scan result to determine whether
maintenance mode is required or not. After a VIB is installed on a live system, if Live-Install-Allowed
and Live-Remove-Allowed are both set to false, the installation result will instruct Update Manager to
reboot the host. During the reboot, Update Manager will automatically put the host into maintenance
mode.
What to do next
If necessary, place the host in maintenance mode. See “Place a Host in Maintenance Mode,” on page 136. If
a reboot is required, and if the host belongs to a VMware HA cluster, remove the host from the cluster or
disable HA on the cluster before the installation or update.
Place a Host in Maintenance Mode

When you specify a target server by using --server=server_name in the procedure, the specified server
prompts you for a user name and password. Other connection options, such as a configuration file or
session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line
Interfaces, or run esxcli --help at the vCLI command prompt.
NOTE Options to the update and install commands allow you to perform a dry run, to specify a specific
VIB, to bypass acceptance level verification, and so on. Do not bypass verification on production systems.
See the vSphere Command-Line Interface Reference.
Prerequisites
n
Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started
with vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.

Specify one or more VIBs to remove in one of the following forms:
n
name
n
name:version
n
vendor:name
n
vendor:name:version
For example, the command to remove a VIB specified by vendor, name and version would take this
form:
esxcli –-server myEsxiHost software vib remove --vibname=PatchVendor:patch42:version3
NOTE The remove command supports several more options. See the vSphere Command-Line Interface
Reference.
Adding Third-Party Extensions to Hosts with esxcli
If a third-party extension is released as a VIB package, and you use the esxcli software vib command to
add the VIB package to your system, the VIB system updates the firewall ruleset and refreshes the host
daemon after you reboot your system.
Otherwise, you can use a firewall configuration file to specify port rules for host services that you want to
enable for the extension. The vSphere Security documentation discusses how to add, apply, and refresh a
firewall rule set and lists the esxcli network firewall commands.
The ESXi 5.0 ruleset.xml format for ESXi 5.0 is the same as in version 4.x for ESX and ESXi, but has two
more tags, enabled and required. The ESXi 5.0 firewall still supports the older format.
Perform a Dry Run of an esxcli Installation or Upgrade
You can use the --dry-run option to preview the results of an installation or upgrade operation. A dry run
of the installation or update procedure does not make any changes, but reports the VIB-level operations that
will be performed if you run the command without the --dry-run option.
When you specify a target server by using --server=server_name in the procedure, the specified server
prompts you for a user name and password. Other connection options, such as a configuration file or
session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line
Interfaces, or run esxcli --help at the vCLI command prompt.

Chapter 6 Upgrading and Migrating Your Hosts
Errors and Warnings Returned by the Installation and Upgrade Precheck Script
The installation and upgrade precheck script runs tests to identify problems on the host machine that can
cause an installation, upgrade, or migration to fail.
For interactive installations, upgrades, and migrations, the errors or warnings are displayed on the final
panel of the installer, where you are asked to confirm or cancel the installation or upgrade. For scripted
installations, upgrades, or migrations, the errors or warnings are written to the installation log.
vSphere Update Manager provides custom messages for these errors or warnings. To see the original errors
and warnings returned by the precheck script during an Update Manager host upgrade scan, review the
Update Manager log file vmware-vum-server-log4cpp.log.
Table 6‑9. Error and Warning Codes That Are Returned by the Installation and Upgrade Precheck Script
Error or Warning
Description
64BIT_LONGMODESTATUS
The host processor must be 64-bit.
COS_NETWORKING
Warning. An IPv4 address was found on an enabled
Service Console virtual NIC for which there is no
corresponding address in the same subnet in the vmkernel.
A separate warning will be output for each such
occurrence.
CPU_CORES
The host must have at least two cores.
DISTRIBUTED_VIRTUAL_SWITCH
If Cisco's Virtual Ethernet Module (VEM) software is found
on the host, the test checks to make sure the upgrade also
contains the VEM software, and that it supports the same
version of the Virtual Supervisor Module (VSM) as the
existing version on the host. If the software is missing or is
compatible with a different version of the VSM, the test
returns a warning, and the result indicates which version
of the VEM software was expected on the upgrade ISO and
which version, if any, were found. You can use ESXi Image
Builder CLI to create a custom installation ISO that
includes the appropriate version of the VEM software.
HARDWARE_VIRTUALIZATION
Warning. If the host processor doesn't have hardware
virtualization or if hardware virtualization is not turned on
in the host BIOS, host performance will suffer. Enable
hardware virtualization in the host machine boot options.
See your hardware vendor's documentation.
MD5_ROOT_PASSWORD
This test checks that the root password is encoded in MD5
format. If a password is not encoded in MD5 format, it
might be significant only to eight characters. In this case,
any characters after the first eight are no longer
authenticated after the upgrade, which can create a security
issue. To work around this problem, see VMware
Knowledge Base article 1024500.
MEMORY_SIZE
The host requires the specified amount of memory to
upgrade.
PACKAGE_COMPLIANCE
vSphere Update Manager only. This test checks the existing
software on the host against the software contained on the
upgrade ISO to determine whether the host has been
successfully upgraded. If any of the packages are missing
or are an older version than the package on the upgrade
ISO, the test returns an error and indicates which software
was found on the host, and which software was found on
the upgrade ISO.
VMware, Inc.
143
vSphere Upgrade
Table 6‑9. Error and Warning Codes That Are Returned by the Installation and Upgrade Precheck Script
(Continued)
Error or Warning
Description
PARTITION_LAYOUT
Upgrading or migration is possible only if there is at most
one VMFS partition on the disk that is being upgraded and
the VMFS partition must start after sector 1843200
POWERPATH
This test checks for installation of EMC PowerPath
software, consisting of a CIM module and a kernel module.
If either of these components is found on the host, the test
checks to make sure that matching components (CIM,
vmkernel module) also exist in the upgrade. If they do not,
the test returns a warning that indicates which PowerPath
components were expected on the upgrade ISO and which,
if any, were found.
PRECHECK_INITIALIZE
This test checks that the precheck script itself can be run.
SANE_ESX_CONF
The file /etc/vmware/esx.conf must exist on the host.
SPACE_AVAIL_ISO
vSphere Update Manager only. The host disk must have
enough free space to store the contents of the installer CD
or DVD.
SPACE_AVAIL_CONFIG
vSphere Update Manager only. The host disk must have
enough free space to store the 4.x configuration between
reboots.
SUPPORTED_ESX_VERSION
Upgrading or migration to ESXi 5.0 is possible only from
version 4.x ESXi or ESX hosts.
TBOOT_REQUIRED
This message applies only to vSphere Update Manager
upgrades. The upgrade fails with this error when the host
system is running in Trusted Boot mode (tboot), but the
ESXi upgrade ISO does not contain any tboot VIBs. This
test prevents an upgrade that can make the host less secure.
UNSUPPORTED_DEVICES
Warning. This test checks for unsupported devices. Some
PCI devices are not supported in ESXi 5.0.
UPDATE_PENDING
This test checks the 4.x host for VIB installations that
require a reboot. This test fails if one or more such VIBs is
installed, but the host has not yet been rebooted. In these
conditions, the precheck script is unable to reliably
determine which packages are currently installed on the
host, so it might not be safe to rely on the rest of the
precheck tests to determine whether an upgrade is safe.
If you encounter this error, restart the host and retry the
upgrade.
After You Upgrade or Migrate Hosts
A host upgrade or migration is not complete until you have ensured that the host is reconnected to its
managing vCenter Server and reconfigured if necessary, and that the host license is reapplied or upgraded.
After you upgrade or migrate a host, take the following actions:
144
n
View the upgrade logs. You can use the vSphere Client to export the log files.
n
If vCenter Server manages the host, you must reconnect the host to vCenter Server by right-clicking the
host in the vCenter Server inventory and selecting Connect.
n
When the upgrade is complete, ESXi is in evaluation mode. The evaluation mode period is 60 days. You
must reapply your license or assign an upgraded license to your product within 60 days after the
upgrade. Use the License Portal and the vSphere Client to configure licensing. See
VMware, Inc.
Chapter 6 Upgrading and Migrating Your Hosts
n
On the VMware Web site, log in to your account page to access the license portal. From the license
portal, upgrade your ESXi license. Use the vSphere Client to assign the upgraded license key to the
host.
n
The host sdX devices might be renumbered after the upgrade. If necessary, update any scripts that
reference sdX devices.
n
After the upgrade, convert any ESX 3.x-style /adv/Disk/MaskLUNs LUN masks to the claim rule
format. Run the esxcli storage core claimrule convert command in the vSphere Command-Line
Interface (vCLI). This command converts the /adv/Disk/MaskLUNs advanced configuration entry
in /etc/vmware/esx.conf to claim rules with MASK_PATH as the plug-in.
CAUTION This conversion will not work for all input MaskLUNs variations. See the vSphere CommandLine Interface Reference.
n
Upgrade virtual machines on the host. See Chapter 7, “Upgrading Virtual Machines,” on page 147.
About ESXi Evaluation and Licensed Modes
After you purchase a host license, VMware provides a serial number that you can use to license vSphere.
You can use evaluation mode to access the full ESXi feature set, including features you have not purchased a
license for.
For example, in evaluation mode, you can use vMotion, HA, DRS, and other features, even if you have not
licensed those features.
The installable version of ESXi is always installed in evaluation mode. ESXi Embedded is preinstalled on an
internal USB device by your hardware vendor. It might be in evaluation mode or prelicensed.
The evaluation period is 60 days and begins when you turn on the ESXi host, even if you start in licensed
mode rather than evaluation mode. Any time during the 60-day evaluation period, you can convert from
licensed mode to evaluation mode. To take full advantage of the 60-day evaluation period, you should
convert to evaluation mode as soon as possible after you first power on the host. See “Convert an ESXi Host
to Evaluation Mode,” on page 145.
For information about licensing the host, see the vCenter Server and Host Management.
Reapplying Licenses After Upgrading to ESXi 5.0
After you upgrade to ESXi 5.0, reapply your host license.
After upgrading, your ESXi 5.0 software returns to evaluation mode until you reapply your license. If you
used part of the 60-day evaluation period before upgrading, the time remaining in your evaluation period is
decreased by the amount already used. For example, if you used 20 days of the evaluation period before
upgrading, your remaining evaluation period after the upgrade is 40 days. See “About ESXi Evaluation and
Licensed Modes,” on page 145.
You can apply your license using the vSphere Client and vCenter Server. See the vCenter Server and Host
Management documentation.
Convert an ESXi Host to Evaluation Mode
You can switch a licensed ESXi host to evaluation mode to explore all the features of ESXi, including
features that you have not licensed.
See “About ESXi Evaluation and Licensed Modes,” on page 145.
Prerequisites
The 60-day evaluation period has not expired.

Upgrading Virtual Machines
7
After you perform an ESX/ESXi upgrade, VMware recommends that you upgrade all the virtual machines
that reside on the host. Upgrading virtual machines ensures that they remain compatible with the upgraded
host software, and can take advantage of new features.
The first step in upgrading virtual machines is to upgrade VMware Tools. If the virtual machines do not
have VMware Tools installed, you can use the VMware Tools upgrade procedure to install VMware Tools.
After you install or upgrade VMware Tools, upgrade the virtual machine hardware.
NOTE Do not use vmware-vmupgrade.exe to upgrade virtual machines.
VMware offers the following tools for upgrading virtual machines:
vSphere Client
Requires you to perform the virtual machine upgrade one step at a time, but
does not require vSphere Update Manager.
vSphere Update
Manager
Automates the process of upgrading and patching virtual machines, thereby
ensuring that the steps occur in the correct order. You can use Update
Manager to directly upgrade virtual machine hardware, VMware Tools, and
virtual appliances. You can also patch and update third-party software
running on the virtual machines and virtual appliances. See “Perform an
Orchestrated Upgrade of Virtual Machines with vSphere Update Manager,”
on page 151 and the Installing and Administering VMware vSphere Update
Managerdocumentation.

About VMware Tools
VMware Tools improves the performance and management of the virtual machine.
VMware Tools is a suite of utilities that you install in the operating system of a virtual machine. VMware
Tools enhances the performance of a virtual machine and makes possible many of the ease-of-use features in
VMware products. For example, the following features are just some of the features that are available only if
VMware Tools is installed:
n
Significantly faster graphics performance and Windows Aero on operating systems that support Aero
n
Copying and pasting text, graphics, and files between the virtual machine and the host or client desktop
n
Improved mouse performance
n
Synchronization of the clock in the virtual machine with the clock on the host or client desktop
n
Scripting that helps automate guest operating system operations
Although the guest operating system can run without VMware Tools, many VMware features are not
available until you install VMware Tools. For example, if you do not have VMware Tools installed in your
virtual machine, you cannot use the shutdown or restart options from the toolbar. You can use only the
power options.
The installers for VMware Tools are ISO image files. An ISO image file looks like a CD-ROM to your guest
operating system. There is an ISO image file for each type of guest operating system, including Windows,
Linux, Solaris, FreeBSD, and NetWare. When you select the command to install or upgrade VMware Tools,
the virtual machine’s first virtual CD-ROM disk drive temporarily connects to the VMware Tools ISO file for
your guest operating system.
For complete information about VMware Tools, see Installing and Configuring VMware Tools.
Upgrading VMware Tools
You can upgrade VMware Tools manually, or you can configure virtual machines to check for and install
newer versions of VMware Tools.
The guest operating system checks the version of VMware Tools when you power on a virtual machine. The
status bar of the virtual machine displays a message when a new version is available.
In Windows virtual machines, you can set VMware Tools to notify you when an upgrade is available. If this
notification option is enabled, the VMware Tools icon in the Windows taskbar includes a yellow caution
icon when a VMware Tools upgrade is available.
To install a VMware Tools upgrade, you can use the same procedure that you used for installing VMware
Tools the first time. Upgrading VMware Tools means installing a new version.
148
VMware, Inc.
Chapter 7 Upgrading Virtual Machines
For Windows and Linux guest operating systems, you can configure the virtual machine to automatically
upgrade VMware Tools. Although the version check is performed when you power on the virtual machine,
on Windows guest operating systems, the automatic upgrade occurs when you power off or restart the
virtual machine. The status bar displays the message Installing VMware Tools ... when an upgrade is in
progress.
IMPORTANT When you upgrade VMware Tools on Linux guest operating systems, new network modules
are available but are not used until you either reboot the guest operating system or stop networking, unload
and re-load the VMware networking kernel modules, and then restart networking. This behavior means that
even if VMware Tools is set to automatically upgrade, you must reboot or re-load network modules to make
new features available.
This strategy avoids network interruptions and allows you to work with VMware Tools over SSH.
You have options for upgrading many virtual machines at the same time.
n
Log in to vCenter Server, select a host or cluster, and use the Virtual Machines tab to specify the virtual
machines on which to perform a VMware Tools upgrade.
n
Use Update Manager to perform an orchestrated upgrade of virtual machines at the folder or
datacenter level.
For best performance and the latest updates, install or upgrade VMware Tools to the VMware Tools version
that is included with the VMware product you are using. Other compatibility options are also available.
n
The version of VMware Tools included in vSphere 5.0 is supported on vSphere 4.x and 5.0 virtual
machines. That is, you can also use this new version of VMware Tools in virtual machines on ESX/ESXi
4.x hosts.
n
Virtual machines in a vSphere 5.0 environment support the versions of VMware Tools included in
vSphere 4.0-5.0. That is, you are not strictly required to upgrade VMware Tools if VMware Tools was
installed from an ESX/ESXi 4.x host.
About Virtual Machines and Host Upgrades
Some virtual machines that you create on ESXi 5.0 hosts are supported on hosts running earlier versions of
ESX/ESXi software.
If you create a virtual machine on an ESXi 5.0 host and select the typical path, the virtual hardware version
is version 8. Virtual machines with virtual hardware version 8 are not supported on hosts running versions
of ESX/ESXi software earlier than ESXi 5.0. When you create virtual machines on ESXi 5.0 hosts, to ensure
that your virtual machines can run on version 4.x ESX and ESXi hosts, select the custom path and select
virtual hardware version 7. Virtual machines that have virtual hardware version 7 work properly on
ESX/ESXi 4.x hosts and ESXi 5.0 hosts, and you can use vMotion to migrate virtual hardware version 7
virtual machines between between ESX/ESXi 4.x hosts and ESXi 5.0 hosts.
Because paravirtualization (VMI) is not supported on ESXi 5.0, you cannot move VMI-enabled virtual
machines from an ESX 3.x or ESX 4.x/ESXi 4.x host to an ESXi 5.0 host when the virtual machines are
powered on. When the VMI-enabled virtual machines are powered off, you can move them from ESX 3.x or
ESX 4.x/ESXi 4.x host to ESXi 5.0 hosts and then remove VMI devices from the virtual machines before
powering on the virtual machines.
VMware, Inc.
149
vSphere Upgrade
Virtual Machine Hardware Versions
The hardware version of a virtual machine reflects the virtual machine's supported virtual hardware
features. These features correspond to the physical hardware available on the ESXi host on which you create
the virtual machine. Virtual hardware features include BIOS and EFI, available virtual PCI slots, maximum
number of CPUs, maximum memory configuration, and other characteristics typical to hardware.
When you create a virtual machine, you can accept the default hardware version, which corresponds to the
host on which you create the virtual machine, or an earlier version. You can use an earlier hardware version
in the following situations:
n
To standardize testing and deployment in your virtual environment.
n
If you do not need the capabilities of the newer version.
n
To maintain compatibility with older hosts.
Virtual machines with hardware versions earlier than version 8 can run on ESXi 5.0 hosts, but do not have
all the capabilities available in hardware version 8. For example, you cannot use 32 virtual processors or
1011GB of memory in virtual machines with hardware versions earlier than version 8.
The vSphere Web Client or the vSphere Client allows you to upgrade virtual machines only to the latest
hardware version. If virtual machines do not have to stay compatible with older ESX/ESXi hosts, you can
upgrade them on ESXi 5.0 hosts. In this case, they are upgraded to version 8.
n
To maintain virtual machine compatibility with ESX/ESXi 3.5 hosts, upgrade the virtual machine on an
ESX/ESXi 3.5 host, which results in a virtual machine upgrade to version 4.
n
To maintain virtual machine compatibility with ESX/ESXi 4.x hosts, upgrade the virtual machine on an
ESX/ESXi 4.x host, which results in a virtual machine upgrade to version 7.
A virtual machine can have an earlier hardware version than that of the host on which it runs in the
following cases:
n
You migrate a virtual machine created on an ESX/ESXi 4.x or earlier host to an ESXi 5.0 host.
n
You create a virtual machine on an ESXi 5.0 host by using an existing virtual disk that was created on
an ESX/ESXi 4.x or earlier host.
n
You add a virtual disk created on an ESX/ESXi 4.x or earlier host to a virtual machine created on an
ESXi 5.0 host.
You can create, edit, and run different virtual machine versions on a host if the host supports that version.
Sometimes, virtual machine actions on a host are limited or the virtual machine has no access to the host.

Chapter 7 Upgrading Virtual Machines
Perform an Orchestrated Upgrade of Virtual Machines with vSphere
Update Manager
An orchestrated upgrade of virtual machines allows you to upgrade VMware Tools and the virtual
hardware for the virtual machines in your vSphere inventory at the same time. You can perform an
orchestrated upgrade of virtual machines at the folder or datacenter level.
Update Manager makes the process of upgrading the virtual machines convenient by providing baseline
groups. When you remediate a virtual machine against a baseline group containing the
VMware Tools Upgrade to Match Host baseline and the VM Hardware Upgrade to Match Host baseline,
Update Manager sequences the upgrade operations in the correct order. As a result, the guest operating
system is in a consistent state at the end of the upgrade.
This workflow describes the overall process to perform an orchestrated upgrade of the virtual machines in
your vSphere inventory.
Procedure

baseline groups, you must first attach existing baselines and baseline groups to these objects.
You can attach baselines and baseline groups to objects from the Update Manager Client Compliance view.
Although you can attach baselines and baseline groups to individual objects, a more efficient method is to
attach them to container objects, such as folders, vApps, clusters, and datacenters. Individual vSphere
objects inherit baselines attached to the parent container object. Removing an object from a container
removes the inherited baselines from the object.
If your vCenter Server system is part of a connected group in vCenter Linked Mode, you can attach
baselines and baseline groups to objects managed by the vCenter Server system with which
Update Manager is registered. Baselines and baseline groups you attach are specific for the Update Manager

The options are Virtual Appliance upgrades, VM Hardware upgrades, and VMware Tools upgrades.
4
Click Scan.
The virtual machines and appliances that you select are scanned against the attached baselines, depending
on the options that you select. All child objects are also scanned. The larger the virtual infrastructure and the
higher up in the object hierarchy that you initiate the scan, the longer the scan takes and the more accurate
the compliance view is.
View Compliance Information for vSphere Objects
You can review compliance information for the virtual machines, virtual appliances, and hosts against
baselines and baseline groups that you attach.
When you select a container object, you view the overall compliance status of the attached baselines, as well
as all the individual compliance statuses. If you select an individual baseline attached to the container object,
you see the compliance status of the baseline.
If you select an individual virtual machine, appliance, or host, you see the overall compliance status of the
selected object against all attached baselines and the number of updates. If you further select an individual

Planning Downtime for Virtual Machines
Plan downtime for each virtual machine during the upgrade process. Typically, this downtime occurs
during the virtual machine upgrade and the VMware Tools upgrade. Depending on your upgrade plan,
some virtual machine downtime might be required during the ESX upgrade.
If an ESX/ESXi host is not managed by vCenter Server, you cannot use vMotion to move virtual machines.
The virtual machines must have some downtime when the ESX/ESXi host reboots after upgrade.
You might not have to shut down more than a single virtual machine at any given time. You can stagger
virtual machine downtimes to accommodate a schedule convenient to you and your customers.
For example:
n
If your virtual machine users are located in diverse time zones, you can prepare by migrating virtual
machines to specific hosts to serve a given time zone. This way you can arrange host upgrades so that
virtual machine downtime occurs transparently outside business hours for that time zone.
n
If your virtual machine users operate around the clock, you can delay downtime for their virtual
machines to normally scheduled maintenance periods. You do not need to upgrade any stage within a
certain time period. You can take as long as needed at any stage.
Downtime for Upgrading Virtual Machines
When you upgrade virtual machines, the required downtime depends on the guest operating system.
When you upgrade VMware Tools, expect the following downtime:
n
No downtime is required for vCenter Server.
n
No downtime is required for ESXi hosts.
n
You must reboot Microsoft Windows virtual machines at the end of the upgrade procedure, or later, for
the upgrade take effect.
n
On Windows guest operating systems, you must reboot the virtual machine three times when you
upgrade VMware Tools and the virtual hardware.
n
For Linux, NetWare, and Solaris guest operating systems, no reboot is required at the end of the
procedure.
During the virtual hardware upgrade, you must shut down the virtual machine for all guest operating
systems.
Table 7-2 summarizes the downtime required by guest operating system and by upgrade operation.

Operating System Specific Packages for Linux Guest Operating
Systems
For vSphere deployments, VMware provides operating system specific packages (OSPs) as a packaging and
distribution mechanism for VMware Tools. These VMware Tools OSPs are packaged using native package
formats and standards such as rpm and deb.
Using OSPs provides the following benefits:
n
You can use the native update mechanisms of the guest operating system to download, install, and
manage VMware Tools.
n
You can upgrade to the latest version of VMware Tools without having to upgrade to the latest version
of vSphere.
n
Because VMware Tools OSPs follow the best practices and standards of the specific Linux operating
system, OSPs use standard mechanisms for determining dependencies among packages. These
mechanisms allow you to audit the packages on virtual machines with or without graphics
components.
n
You can use standard operating system tools to examine OSPs during VMware Tools installation. This
process allows you to easily determine which components to install and to verify the validity of the
packaging.
IMPORTANT Use OSPs if you want to use native update mechanisms, rather than vCenter Server, to manage
updates for VMware Tools. If you use an OSP, the VMware Tools status is unmanaged on the virtual
machine Summary tab. The status unmanaged means that you cannot use vCenter Server to manage
VMware Tools and you cannot use vSphere Update Manager to upgrade VMware Tools.
For more information, go to the VMware Operating System Specific Packages Web site, at
http://www.vmware.com/download/packages.html.
Perform an Automatic Upgrade of VMware Tools
When you start an automatic upgrade of VMware Tools, you do not need to perform any operations in the
guest operating system that is running on the virtual machine. The automatic upgrade uninstalls the
previous version of VMware Tools, installs the latest version that is available for your ESXi host, and if
necessary, reboots the virtual machine.
Automatic VMware Tools upgrade is not supported for virtual machines with Solaris or NetWare guest
operating systems.
Prerequisites
The following requirements are for each virtual machine in the upgrade:
n
Power on the virtual machine.
n
Verify that the guest operating system is running.

IMPORTANT When you upgrade VMware Tools on Linux guest operating systems, new network modules
are available but are not used until you either reboot the guest operating system or stop networking, unload
and re-load the VMware networking kernel modules, and then restart networking. This behavior means that
even if VMware Tools is set to automatically upgrade, you must reboot or re-load network modules to make
new features available.
This strategy avoids network interruptions and allows you to work with VMware Tools over SSH.

Chapter 7 Upgrading Virtual Machines
Upgrade Virtual Hardware
You can upgrade the hardware version of virtual machines to the latest version of ESXi. For virtual
machines that are running on ESXi 5.x, VMware recommends that you upgrade the virtual hardware to
version 8.
Consider the following points:
n
When you upgrade from virtual hardware version 4 to version 8 the upgrade is reversible if you take a
virtual machine backup or snapshot before performing the upgrade.
n
Upgraded virtual machines cannot be powered on by an ESX 2.x host, even if relocated to a VMFS2
datastore.
n
To automate this process, consider using Update Manager for virtual machine upgrades. See the
Installing and Administering VMware vSphere Update Manager documentation. Update Manager takes
automatic snapshots before performing virtual machine upgrades. See “Perform an Orchestrated
Upgrade of Virtual Machines with vSphere Update Manager,” on page 151.
n
When you upgrade virtual hardware, no downtime is required for vCenter Server or ESX/ESXi hosts.
For virtual machines, the only significant downtime is the time to reboot the guest operating systems.
Prerequisites
n
Create a backup or snapshot of the virtual machine. See the vSphere Virtual Machine Administration
documentation.
n
Upgrade VMware Tools. On Microsoft Windows virtual machines, if you upgrade the virtual hardware
before you upgrade VMware Tools, the virtual machine might lose its network settings.
n
Verify that all .vmdk files are available to the ESX/ESXi host on a VMFS3, VMFS5, or NFS datastore.
n
Verify that the virtual machines are stored on VMFS3, VMFS5 or NFS datastores.
n
Determine the version of the virtual hardware by selecting the virtual machine from the vSphere Client
or vSphere Web Client and clicking the Summary tab. The VM Version label displays the virtual
hardware version.

Example Upgrade Scenarios
8
Upgrade scenarios for vSphere 4.1 include cases with and without clustered hosts, hosts that you upgrade
on the same machine on which they are currently running (in-place upgrades), and hosts that you upgrade
using different machines (migration upgrades).

Upgrading Environments with Host Clusters
This example scenario shows how you can use vSphere Update Manager to simplify the host and virtual
machine upgrade process and minimize downtime in environments that include host clusters.
For this scenario, verify the following details about your vSphere environment.
n
You must have VirtualCenter 2.5 Update 6 or later or vCenter Server 4.x.
n
You must have vSphere Update Manager.
n
All your hosts must be ESX 4.x/ESXi 4.x or later.
n
If your environment has vCenter Guided Consolidation, uninstall it before upgrading.
The following list of tasks provides a high-level overview of the upgrade process.
1
Run the vCenter Host Agent Pre-Upgrade Checker.
2
Upgrade vCenter Server 2.5 Update 6 or higher or vCenter Server 4.x to vCenter Server 5.0.
VMware, Inc.
a
Make sure your database is compatible with vCenter Server 5.0. See the VMware Product
Interoperability Matrix at
http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
b
Make sure that you have the required permissions to perform this procedure. See “Prerequisites for
the vCenter Server Upgrade,” on page 30.
169
vSphere Upgrade
c
Take a full backup of the vCenter Server database. See your database documentation.
d
Back up the vCenter Server SSL certificates.
The downtime required for this upgrade is based on the amount of data in the database. During this
time, you cannot perform provisioning operations, such as cloning or creating virtual machines.
After the upgrade, the hosts are automatically connected to vCenter Server 5.0 if you select that option
during the upgrade process. vSphere High Availability (HA) and vSphere Distributed Resource
Scheduler (DRS) clusters are automatically reconfigured. (Check to ensure that the automatic
reconfiguration is successful. In some cases, you might need to reconfigure the clusters manually.)
vCenter Server 5.0 is supported only on 64-bit systems. The upgrade method you use depends on what
version of VirtualCenter or vCenter Server you are upgrading and on what system it is currently
installed. For a detailed description of the upgrade procedure, see “Preparing for the Upgrade to
vCenter Server,” on page 27 and Chapter 4, “Upgrading to vCenter Server 5.0,” on page 27.
3
Install the vSphere Client.
You can install the vSphere Client on the same machine with your previous version of the vSphere
Client. You must have the previous version of the vSphere Client to connect to previous versions of
vCenter Server and ESX/ESXi.
For a detailed description of the procedure, see “Upgrade the vSphere Client,” on page 62.
4
Upgrade vSphere Update Manager to vSphere Update Manager 5.0.
5
Use Update Manager to upgrade ESX 4.x/ESXi 4.x or higher hosts to ESXi 5.0.
Update Manager puts the host into maintenance mode before upgrading the host. The downtime for
the procedure depends on the network speed and the server boot time.
For a detailed description of the procedure, see the Installing and Administering VMware vSphere Update
Manager documentation.
6
Use Update Manager to upgrade your virtual machines. Update Manager ensures that the VMware
Tools upgrade and the virtual hardware upgrade happen in the correct order to prevent loss of your
network connectivity. Update Manager also performs automatic backups of your virtual machines in
case you need to roll back after the upgrade. You can upgrade hosts in clusters without powering off
the virtual machines if Distributed Resource Scheduler is available for the cluster.
7
Upgrade your product licenses:
8
a
Either your new license keys are sent to you in email, or you get them using the license portal.
b
Apply the new license keys to your assets using vCenter Server.
Use the vSphere Client to upgrade to VMFS5.
See the information on upgrading datastores to VMFS5 in the vSphere Storage documentation.
Upgrading Environments Without Host Clusters
If you have standalone ESX 4.x/ESXi 4.x hosts, you can upgrade your hosts and the vSphere Client to
upgrade your virtual machines. This scenario provides a high-level overview of the upgrade process when
you do not have host clusters and you do not have vSphere Update Manager.
This scenario applies to your environment whether or not you have vCenter Server.
Verify the following details about your vSphere environment.
n
170
All your hosts must be ESX 4.x/ESXi 4.x or higher.
VMware, Inc.
Chapter 8 Example Upgrade Scenarios
n
If your environment has vCenter Guided Consolidation, uninstall it before upgrading.
1
Run the vCenter Host Agent Pre-Upgrade Checker.
See “Run the vCenter Host Agent Pre-Upgrade Checker,” on page 37.
2
If you have vCenter Server, upgrade to vCenter Server 5.0.
See Chapter 4, “Upgrading to vCenter Server 5.0,” on page 27.
The downtime required for this upgrade is based on the amount of data in the database. During this
time, you cannot perform provisioning operations, such as cloning or creating virtual machines.
After the upgrade, the hosts are automatically connected to vCenter Server 5.0 if you select that option
during the upgrade process.
3
Install or upgrade the vSphere Client to version 5.0. See “Upgrade the vSphere Client,” on page 62
You can install the vSphere Client on the same machine with your previous versions of the vSphere
Client. You must have the previous versions of the vSphere Client to connect to previous versions of
vCenter Server and ESX/ESXi.
4
For all hosts, perform an interactive upgrade using an ESXi ISO installer image stored on a CD, DVD, or
USB flash drive to upgrade ESX 4.x/ESXi 4.x. See Chapter 6, “Upgrading and Migrating Your Hosts,” on
page 77 and “Upgrade or Migrate Hosts Interactively,” on page 113.
This procedure involves putting the host into maintenance mode before you upgrade the host. The
downtime for the procedure depends on the network speed and the server boot time.
In case of upgrade failure, the process does not support rollback to the previous release.
5
Upgrade your virtual machines. See Chapter 7, “Upgrading Virtual Machines,” on page 147.
6
Get your license key either in email or by using the license portal.
7
Apply the new license keys to your assets using the vSphere Client..
8
Use the vSphere Client to upgrade your datastore to VMFS5.
See information about upgrading datastores to VMFS5 in the vSphere Storage documentation.
Moving Virtual Machines Using vMotion During an Upgrade
This scenario is a migration upgrade. The migration upgrade is a managed transition rather than a strict
upgrade. By using vMotion to move virtual machines directly from one production host to another
production host, you minimize downtime of the virtual machines.
The following example provides a high-level overview of the upgrade process in an environment with
ESX 3.5/ESXi 3.5 or higher and vCenter Server 5.0, using vMotion to migrate your running virtual machines
to ESXi 5.0. The hosts in your environment must be licensed for and able to use vMotion.
You can perform a migration upgrade without vMotion. The only difference is the amount of downtime for
the virtual machines.
A migration upgrade calls for sufficient resources to run the production environment partly on older hosts
and partly on upgraded hosts. Any required redundancies and safeguards must be available on both
upgraded and non-upgraded infrastructure during the transition.
Prerequisites
n
Verify that one or more machines meets ESXi 5.0 requirements.
n
Verify that empty host storage is sufficient to hold a portion of your production virtual machines.
Ideally, the storage is large enough to hold all of the migrated virtual machines. A larger capacity for
virtual machines on this extra storage means fewer operations are required before all your virtual
machines are migrated.
VMware, Inc.
171
vSphere Upgrade
n
If your environment has vCenter Guided Consolidation, uninstall it.
n
Run the vCenter Host Agent Pre-Upgrade Checker. See “Run the vCenter Host Agent Pre-Upgrade
Checker,” on page 37.
n
Upgrade VirtualCenter 2.5 Update 6 or higher or vCenter Server 4.0 to vCenter Server 5.0. See
Chapter 4, “Upgrading to vCenter Server 5.0,” on page 27.
The downtime required for this upgrade is based on the amount of data in the database. During this
time, you cannot perform provisioning operations, such as cloning or creating virtual machines.
n
Install the version 5.0 vSphere Client. See “Upgrade the vSphere Client,” on page 62.
n
If your environment has vSphere Update Manager, upgrade it to the latest version. See Chapter 5,
“Upgrading Update Manager,” on page 73.
Procedure
1
Use vMotion to move the virtual machines from the ESX 3.5/ESXi 3.5 or higher host.
2
Upgrade the host to ESXi 5.0, or perform a fresh installation of ESXi 5.0.
3
Add the ESXi 5.0 host to vCenter Server.
4
Use vMotion to move the virtual machines that you removed from the ESX 3.5/ESXi 3.5 or higher host
before the upgrade.
For vMotion to work, the hosts must be managed by the same vCenter Server instance.
What to do next
For all hosts and virtual machines in the migration upgrade, take the following actions.
n
Upgrade your virtual machines. See Chapter 7, “Upgrading Virtual Machines,” on page 147.
n
Upgrade your product licenses:
n
a
Get your new license keys by email, or by using the license portal.
b
Apply the new license keys to your assets using the vSphere Client (or vCenter Server if you have
it).
Use the vSphere Client to upgrade the host datastore to VMFS5.
See the information about upgrading datastores to VMFS5 in the vSphere Storage documentation.
Moving Powered Off or Suspended Virtual Machines During an
Upgrade with vCenter Server
In a cold migration upgrade, you power off or suspend the virtual machines that you move to a new host.
When you use cold migration to move virtual machines, more downtime is required for the virtual
machines.
This scenario assumes that the hosts do not have vMotion capabilities.
Upgrades using cold migrations are useful for situations that require a multistep upgrade, such as upgrades
from versions lower than ESX 4.x. Such upgrades require upgrading to ESX 4.x and then upgrading to ESXi
5.0.

Upgrading to vCenter Server on a New Machine
The vCenter Server installation media include a data migration tool that you can use to migrate
configuration information such as port settings, SSL certificates, and license information from the source
vCenter Server machine to the new machine. Instead of performing an in-place upgrade to vCenter Server,
you might want to use a different machine for your upgrade. If you are upgrading from a version of
VirtualCenter or vCenter Server installed on a 32-bit platform, you must use this method to upgrade to a 64bit platform.
You can also use the data migration tool to migrate a SQL Server Express database that is installed by the
vCenter Server installer on the same machine as vCenter Server. If you use another database that is installed
on the vCenter Server machine, you must back up and move the database manually to the new machine. If
the database is installed on a different machine from vCenter Server, you can leave the database in place and
create a DSN on the destination machine to connect to it.
If VMware vSphere Update Manager or vCenter Orchestrator is installed on the same machine as vCenter
Server, you can use the data migration tool to migrate configuration data for these products. You can also
use the tool to migrate the Update Manager database if it is a SQL Server Express database installed on the
same machine as Update Manager and vCenter Server. You cannot use the data migration tool to migrate
the vCenter Orchestrator database. See Installing and Configuring VMware vCenter Orchestrator for
information about upgrading these products.
VMware, Inc.
173
vSphere Upgrade
The following process shows the upgrade path.
1
If you are not using a SQL Server Express database installed on the same machine as vCenter Server,
create a backup of the database.
2
Run the backup.bat script of the data migration tool on the source machine to create a backup of the
vCenter Server configuration.
3
Copy the configuration data to the destination machine.
See “Back Up VirtualCenter or vCenter Server Configuration with the Data Migration Tool,” on page 50
4
5
If you are not using a SQL Server Express database installed on the same machine as vCenter Server,
perform one of the following actions to move the database:
n
Restore the database on the destination machine.
n
Detach the database on the source machine, copy the database files to the destination machine, and
attach the database on the destination machine.
Run the install.bat script on the destination machine.
This script launches the vCenter Server installer and installs vCenter Server with the configuration
settings backed up by the backup.bat script.
For information about this process, see“Upgrade to vCenter Server on a Different Machine and Upgrade the
Database,” on page 43
Migrating ESX 4.x or ESXi 4.x Hosts to ESXi 5.0 in a PXE-Booted Auto
Deploy Installation
This high-level overview describes the process for migrating an ESX/ESXi 4.x host to an ESXi 5.0 installation
that is deployed by using vSphere Auto Deploy.
This scenario assumes the following details about your vSphere environment.
n
The hosts that you are migrating are managed by a vCenter Server running VirtualCenter 2.5 Update 6
or later or vCenter Server 4.x.
n
All hosts managed by that vCenter Server are running ESX/ESXi 3.5 Update 5 or ESX/ESXi 4.x.
The following tasks provide an overview of the migration process.
1
Create host profiles for the ESXi 4.x hosts to be migrated and attach the host profiles to the hosts.
See the vSphere Host Profiles documentation.
2
Upgrade the 4.x vCenter Server to version 5.0.
See Chapter 4, “Upgrading to vCenter Server 5.0,” on page 27.
3
Prepare your Auto Deploy server and environment.
This preparation includes setting up the DHCP and TFTP servers that are used to PXE-boot Auto
Deploy host machines and installing VMware PowerCLI.
See the information about preparing for vSphere Auto Deploy in the vSphere Installation and Setup
documentation.
4
Apply an image profile for an ESXI 5.0 host that is deployed by using the Auto Deploy PowerCLI
commands.
See the information about Auto Deploy in the vSphere Installation and Setup documentation.
5
Use vSphere vMotion to evacuate all virtual machines from the hosts to be migrated, and place the
hosts in maintenance mode.
See the vCenter Server and Host Management documentation.
174
VMware, Inc.
Chapter 8 Example Upgrade Scenarios
6
Reboot the hosts, enter the BIOS, and reconfigure the hosts to boot from the network.
See the information about Auto Deploy in the vSphere Installation and Setup. For ESXi 4.x hosts with
compatible host profiles, the host configuration will be restored.
7
When one host is booted, complete any host configuration that was not migrated and take a host profile
from the host.
See the vSphere Host Profiles documentation.
8
Clone the host profile and attach the profile to the other migrated hosts.
See the vSphere Host Profiles documentation.
9
Update the answer file of each cloned profile to provide host-specific configuration details, such as the
IP configuration.
See the vSphere Host Profiles documentation.
Upgrading vSphere Components Separately in a VMware View
Environment
If you upgrade vSphere components separately from VMware View components, you must back up some
View data and reinstall some View software.
Instead of performing an integrated upgrade of VMware View and vSphere components, you can choose to
first upgrade all View components and then upgrade vSphere components, or the reverse. You might also
upgrade only vSphere components when a new version or update of vSphere is released.
When you upgrade vSphere components separately from View components, you must perform the
following additional tasks:
1
Before you upgrade vCenter Server, back up the vCenter Server database and the View Composer
database.
2
Before you upgrade vCenter Server, back up the View LDAP database from a View Connection Server
instance by using the vdmexport.exe utility.
For instructions, see the VMware View Administration document. If you have multiple instances of
View Connection Server in a replicated group, you need to export the data from only one instance.
3
If you use View Composer, after you upgrade all ESX/ESXi hosts that are managed by a particular
vCenter Server instance, restart the View Composer service on that host.
4
After you upgrade VMware Tools in virtual machines that are used as View desktops, reinstall
View Agent.
Reinstalling View Agent guarantees that the drivers in the virtual machine remain compatible with the
other View components.
Step-by-step instructions for running the View Agent installer appear in the VMware View
Administration document.
