We are doing very similar this weekend. We have just added Unity 11.5x and it is incompatible, licensing, with our CUCM 10.5. Our plan is to upgrade all this weekend but understand that you can upgrade in the non active environment and then cut over when you wish. But will know more about the hurdles after this weekend.

The newer CSR matrix is not very useful (or maybe I'm not interpreting it correctly) Our Software versions are below. CUCM - 10.5.2.10000-5 CUPS IM&P - 10.5.2.22900-2 UNITY - 10.5.2.10000-5 EXPRESSWAY- 8.8.1 We are planning a potential staggered upgrade to 11.5.SU2 or perhaps 11.5.SU3. Where we would one weekend upgrade say the CUCM then next the Unity etc etc... So wanted to know, for example if our Unity would work correctly with the new CUCM Version and visa versa. Many thanks Jon Fox
