Nokia recommends performing this migration during a maintenance window. This migration process is service-impacting. Before the migration can begin, the data-trigger node on the group interface must be shut down, then all the data-triggered hosts must be cleared.
To migrate data-trigger hosts:
Remove the existing subscriber interface and recreate the new 128-bit subscriber interface, group interface, and related parameters. Removing the existing subscriber interface may require clearing data-triggered subscribers from the system.
Update the AAA (RADIUS or Diameter) or LUDB parameters related to the MSAP or SAP. If the end-subscriber is assigned a new IP address, all traffic using the old IP-address is dropped until the new IP address is in use.
To complete the migration, the subscriber must send a data packet for authentication using the new assigned IP address.
