Cisco IOS Release 12.4(15)XR2 is a special release that is developed on Cisco IOS Release 12.4. 

Cisco IOS Release 12.4(15)XR2 supports the same features that are in Cisco IOS Release 12.4, with the 
addition of the Cisco PDSN feature.

The following table lists currently available or planned PDSN releases and the migration path to the 
SAMI platform:

Based on 

, there are many possible migration scenarios. In this document, we focus on those 

scenarios closest to current customer deployments. The actual migration path has to be determined 
per-customer end-to-end deployment. Additionally, migration should be engineered, and we recommend 
that you perform the migration in a maintenance window. 

Customers may take this opportunity to redesign their network, for example, redesigning IP addresses 
scheme and configuring the routing protocols, network connectivity between PDSN and Home Agent, 
application  connectivity between PDSN and AAA servers, routing on the new SAMI PDSN / Home 
Agent, etc.
