We have a Cisco 3845 with AIM-CUE version 2.1. We are planning to upgrade the CUE to 8.0, to work with Cisco CUCM 8.5. As per compatibility matrix, the steps would need to upgrade the CUE through multiple stages to get it to 8.0. The licenses as well need to be migrated to reach the 8.0 version.
Can the AIM-CUE be upgraded to 8.0 or is a new module required?
