CUCM 11.5.1 upgrade to 12.5.1 for UCCE 11.5.1 setup

[Ramamoorthy Shanmugam]

Dear Team,

We are running UCCE  11.5(1) with CUCM 11.5(1) now planning to upgrade only CUCM to 12.5(1) for some reason.

 Please let me know UCCE 11.5.x  will support CUCM 12.5.x. As per cisco Compatibility Matrix 11.6.x only will support CUCM 12.5(1)

Please advise can I upgrade CUCM from 11.5.1 to 12.5.1?

11.5.x

CUCM 12.5 is NOT supported with CCE 11.5. If the upgrade to CUCM 12.5 is really that important, then CCE 11.6 should be considered. Going from 11.5 to 11.6 is incredibly simply
