Release Notes for the Cisco Mobile Wireless Home Agent Feature in Cisco IOS Release 12.4(15)XM2
System Requirements
offers several migration paths:
Feature Compatibility and Seamless Migration
Migration means far more than simply replacing MWAM modules with SAMI modules. It should be well
designed, and conducted in a way that has minimal impact on the existing mobile subscriber’s service
connections.
designed, and conducted in a way that has minimal impact on the existing mobile subscriber’s service
connections.
If there is no redundancy backward compatibility on Home Agent R4.0, HA-SLB can be enabled and
configured to avoid service-disruption, which requires extra network configuration and provisioning. If
there is redundancy backward compatibility on Home Agent R4.0, network configuration and
provisioning will be minimal.
