Introduction
Note
This migration guide contains key information and steps that will help ensure a successful migration from extant Cisco IOS XE 3S releases to the Cisco IOS XE 16.2 release. It is critical that you read this information before you begin migration to ensure that you have completed all the prerequisites and that you understand the migration process.
Developed for wide deployment in the world’s most demanding enterprise, access, and service provider networks, the Cisco IOS software delivers seamless integration of technology innovation with business applications.
Cisco IOS XE 16 (evolved from Cisco IOS XE) introduces Cisco’s next generation of Network Operating System that tightly integrates a broad range of routing and switching portfolio hardware. Feature integration with the earlier releases for each of the platforms, Cisco IOS XE 16 helps you prepare your network to take advantage of new technologies such as, Software Defined
Network (SDN) and Network Function Virtualization (NFV), coupled with service integration for hosted applications. This cross-platform integrated model reduces total cost of ownership, helping the organization qualify, deploy, and maintain a single combined cross-product software.
Cisco IOS XE 16 supports the Enterprise Networking products through the following releases:
1
Cisco IOS XE Denali 16.1 software release addresses the Catalyst switch products.
2
Cisco IOS XE Denali 16.2 software release addresses the access and edge routing products.

Information About Software Licensing
Cisco IOS XE Denali 16.2 has the same type of licensing options and procedures as Cisco IOS XE 3.17, except for the Cisco ASR
1000 modular platforms, which support IP base, AIS, and AES license options.
There are three types of software licenses: Evaluation, Right-To-Use (RTU), and Permanent.
The steps in the
9 show you how to enable the built-in Evaluation license. Evaluation licenses are temporary licenses that are valid for 60 days. To enable an evaluation license, you must accept the end user license agreement (EULA). When the time allowed for an evaluation license expires, the license is automatically upgraded to an RTU license. Use the license boot level [ adventerprise | advipservices
] command to enable the Evaluation license.
You can choose to upgrade to the RTU license before the 60 days evaluation period expires. Use the license right-to-use move
license-name command to upgrade the Evaluation license to the RTU license.
Permanent licenses are perpetual; that is, no usage period is associated with them. Once a Permanent license is installed, all the permissions needed to access the corresponding features in the software image are provided. Use the license install license-key command to enable the Permanent license.
For more information about Temporary and Permanent licenses, see the Cisco IOS Software Activation Conceptual Overview chapter at http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/csa/configuration/xe-16/csa-xe-16-book/csa-concepts.html
.
For more information about RTU, see the Configuring a Cisco Right-To-Use License chapter at http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/csa/configuration/xe-3s/asr1000/csa--xe-3s-asr1000-book/csa--xe-3s-asr1000-book_chapter_0101.html

Downgrading from Cisco IOS XE Denali 16.2 to Cisco IOS XE 3S—Cisco ASR 1000 Series
If you choose to downgrade from Cisco IOS XE Denali 16.2 to a Cisco IOS XE 3S release, you do not need to downgrade the
ROMMON. The ROMMON is backward compatible. You can downgrade the IOS, but you can keep the same ROMMON.

Before You Begin
Make sure that you uninstall any virtual-services before upgrading to Cisco IOS XE Denali 16.2.

Downgrading from Cisco IOS XE Denali 16.2 to Cisco IOS XE 3S—Cisco ISR 4000 Series
Note
You must uninstall any virtual-service (Snort or ISR-WAAS) before starting the downgrade. After you finish with the downgrade, you must install the virtual-services again.
If you choose to downgrade from Cisco IOS XE Denali 16.2 to a Cisco IOS XE 3S release, you do not need to downgrade the
ROMMON. The ROMMON is backward compatible. You can downgrade the IOS, but you can keep the same ROMMON.
