One of our customer is using call manager version 4.1 with MCS 7800 series hardware and would like to replace the hardware to Cisco Business Edition 7000H Svr (M4) with Cisco unified communication manager 11.x, Is it possible migrate the IP Phone license from call manger version 4.1 to CUCM 11.x
The customer has around 1000 licenses in call manager 4.1
There might be a way, i am not sure. what i can tell you is, its far from supported BARS is the way to go with this migration. While using the ways above to migrate your CUCM you would get support from TAC and others.
