This document describes how to use the Upgrade Wizard to
upgrade your LANGuardian installation to version 11.0.
LANGuardian 11.0 is the first 64-bit version of our software. The 64-bit
version offers many benefits, including faster performance, support for
larger memory configurations, and support for a wider range of
peripherals. Most of all, it enables LANGuardian to keep pace with evergrowing network traffic rates and provide an improved user experience.
We strongly recommend that all customers upgrade to LANGuardian 11.0
as soon as possible. The LANGuardian Upgrade Wizard guides you
through the upgrade process.
For technical reasons associated with switching to a 64-bit architecture,
the existing LANGuardian traffic database must be rebuilt as part of the
upgrade to version 11.0. You can rebuild the database by exporting it to a
Windows file share and importing it after the software upgrade has
completed.
Exporting and importing your traffic data can take a long time, depending
on the size of the database. As alternatives to exporting the entire
database, you can export only a subset of the data, or you can discard your
existing traffic data and start your upgraded LANGuardian system with an
empty database.
A flowchart of the upgrade process is shown in Figure 1.

The migration wizard is divided into two parts:

Part 1 runs on your existing LANGuardian system before the migration
begins. This part downloads the upgrade package, saves your current
configuration and, optionally, saves your LANGuardian traffic database.

Part 2 runs on the upgraded LANGuardian system after it reboots. This
part imports your traffic database if you exported it in Part 1.
Part 1: Existing LANGuardian system
Before you begin
The LANGuardian system configuration includes a Software update URL
setting. Your LANGuardian system automatically downloads software
updates from this URL whenever they are available.
Before you begin the upgrade, you must change the Software update
URL setting to point to the location that contains the upgrade package (by
default, it points to the location of LANGuardian 10.x updates). This will
enable LANGuardian to download the latest version in preparation for the
upgrade.
Follow these steps to change the Software update URL setting:
1. Click on
in the LANGuardian menu bar and select Configuration.
2. On the Configuration page, scroll down to the System section.
3. Click Configuration, set the IP address, SNMP collectors etc of
the system.
4. Scroll down to the Software update URL field and enter the following
value:
http://downloads.netforttechnologies.com/software/lg_migrate/
Click Save.
5. In the background, LANGuardian will download the software update.
Wait at least one hour for the download to complete.
6. After the download is complete, LANGuardian will display an upgrade
notification in the LANGuardian dashboard.

LANGuardian displays some information about the upgrade. Click Start
the LANGuardian Upgrade Wizard.
Introduction
This step gives an overview of the upgrade process. Click Next to
continue.
Configuration Data
Your configuration data – accounts, network settings, custom reports,
dashboards, alerts, and so on – is automatically migrated during the
upgrade. However, as a precaution, we recommend saving your
configuration data before proceeding with the upgrade.

Using the LANGuardian Upgrade Wizard
Click the link to download the configuration file, then click Next to
continue.
Database options
The upgrade to version 11.0 involves underlying technical changes that
require the LANGuardian database to be rebuilt. To rebuild the database,
you must export it to a Windows file share and then import it after the
upgrade has completed.
If the database is very large, exporting it can take a long time. If you do not
have reporting or compliance requirements to retain all the data, you can
export a subset of the data, or you can start your upgraded LANGuardian
system with an empty database.
The migration wizard lists the size of the LANGuardian database.
Select one of the export options, then click Next to continue.

Using the LANGuardian Upgrade Wizard
Database location
If you chose to export some or all of the traffic database, the next step is
to specify a Windows file share location in which to temporarily store the
database until after the upgrade (the wizard will skip this step if you chose
not to export your LANGuardian database).
Enter the required details:

IP address

NetBIOS name

Domain (optional)

Share name and path (format: share-name\folder\subfolder)

Username

Password
Click Verify to make sure the details are correct. The upgrade wizard will
verify your credentials, check that the specified share exists, and display a
status message, for example:
When the file share details are verified, click Next to continue.

Database filter
If you chose to export a subset of the traffic database, the next step is
select the data you want to export (the wizard will skip this step if you
chose to export the entire database).
You can select data by year, month, and day. As you select and deselect
data, LANGuardian shows a running total of the amount of data to be
exported.
Note
Only the data you select will be preserved when you upgrade your
LANGuardian system to version 11.0. All other traffic data will be lost.
When you have selected the data you want to export, click Next to
continue.

Export database
If you chose to export some or all of the traffic database, the final step
before upgrading LANGuardian is to export the traffic data to the specified
file share (the wizard will skip this step if you chose not to export your
database).
To preserve the integrity of your traffic database, LANGuardian will stop
monitoring your network traffic while the database export is in progress.
Click Export when you are ready to export your database.
The upgrade wizard will display a progress indicator and status messages
while exporting the data.

Using the LANGuardian Upgrade Wizard
When the upgrade wizard confirms that the database has been exported
successfully, click Next to continue.
Upgrade LANGuardian
Having saved your configuration data and, optionally, exported your traffic
database, you are now ready to upgrade your LANGuardian system to
version 11.0.
Click Upgrade.
LANGuardian will install version 11.0. Then it will shutdown and restart.
Part 2: Upgraded LANGuardian system
After the LANGuardian system restarts, the upgrade to 64-bit
LANGuardian is complete.
If you chose to start monitoring with an empty LANGuardian system, no
further action is necessary.
If you exported some or all of your traffic database, the upgrade wizard
will prompt you to restore the database.

Database import options
The upgrade wizard gives you options to import the traffic data you
exported in Part 1 or start again with an empty database.
Select an option and click Next continue.
Database import location
The next step is to specify the access credentials and location of the
Windows file share to which you exported the traffic database during Part
1 of the upgrade (the wizard will skip this step if you chose not to import
the database).
Enter the required details:

IP address

Share name and path (format: share-name\folder\subfolder)

Username


Click Verify to make sure the details are correct. The upgrade wizard will
verify your credentials, check that the specified share exists, and display a
status message, for example:
When the file share details are verified, click Next to continue.
Import database
The final step in upgrading LANGuardian to version 11.0 is to import the
traffic database (the wizard will skip this step if you chose not to import
the database).
Click Import when you are ready to begin importing the database.
The upgrade wizard will display a progress indicator and status messages
while importing the data.
11
Using the LANGuardian Upgrade Wizard
The upgrade wizard will display the following messages when the data has
been imported successfully.
Click Next to continue.
Finish and restart
The migration is now complete. LANGuardian will shutdown and restart.
When it restarts, you can resume normal use of your LANGuardian
system.
