Hi All
I am planning to upgrade our Cisco Unified Communication Manager cluster from 9.1.2 to 10.5. We do have 2 Cisco Unified Attendant Admin Premium Edition Servers 9.1.1 and am not sure if this version will be compatible with CUCM 10.5.
Do we need to update the Cisco Unified Attendant Admin Premium Edition servers or not. To which flavor or version, we need to upgrade.
Advance Thanks
Prasanth Thomas
