through DMA process. We have noticed that impa configuration is migrated correctly. but we have noticed that Manager Phone when migrate to CUCM V6.1.2 is not ok for IPMA. for this work, we are logout Manager EM and login it again. After that IPMA is ok.
Does it normal to logout/login Manager Phone after Migrate to CUCM V6 befor IPMA works.
Does someone has seen that before or any document explain how IPMA works?
