We are proceeding with migrating from CUCM 8.0 and Unity 8.0.3 (Windows, not Unity Connection) to CUCM 10, Unity Connection and IM/Presence. Due to various pressure from business we had planned to migrate CUCM from 8 to 10 first and then follow up with Unity to Unity Connection 2-3 months later. However, we have checked compatibility between Unity 8.0.3 and CUCM and found there is no support available to run 8.0.3 and CUCM 10.0 . Cisco TAC case also confirmed the same.
Although it may be unsupported due to no specific testing - does it work ? Has anyone operated in this setup with Unity 8.0.3 and CUCM 10.0 and if so were there any issues ?
Thanks a lot for any info that can be provided on this.
Solved! Go to Solution.
Thanks a lot. we'd be the same, migrating to UC 10 in 2-3 months after this migration. It's simply we want/need to get to CUCM 10 first if at all possible.
