Current setup has CUCM 9.1(2) and I understand for enabling Jabber MRA, CUCM version 9.1(2) SU1 is required at the minimum. Hence I am planning to upgrade the CUCM cluster to 9.1(2) SU3. CUCM is intergrated with Unity connection ver 9.1(2) & Presence 9.1(1). I would like to know whether there is any compatability issues with these version as I will be upgrading only CUCM to SU3 now. Does the other applications needs to be upgraded to work with CUCM 9.1(2) SU3. I could not see any compatability issues with avaialble Cisco documents. But just thought of checking the forum to confirm the same. Thanks.
