We have a CCM 4.2 (4 CCM servers, 2 IPCC servers, 1 Unity and 1 CCC ) and CUCM 6.0 (1CCM, 1 IPCC server) cluster simultaneously used in our organization. The CUCM came in much later. Well, my question is when I added the 6x CallManager as a device to the CUOM for monitoring, it came up grayed.
My question however is that if 2 different CallManager Clusters can coexist on CUOM? we Have CUOM version 2.0
