Failed to Install CUP 12.5 config validation with pub failed

[ausjustin]

Trying to install a lab IM&P version 12.5.  The CUCM publisher is already installed and the Subscriber installed fine.  Trying to install the IM&P now but running into this error:

Configuration validation with Publisherfailed.

The current deployment cups do not match the deployment configured on Cisco Unified Communications Manager Publisher.

I have verified and double verified and triple verified the hostname, IP address, security password, etc.  I have even changed the security password but still having the same issue.

The only thing I can think of is that the CUCM is on version 12.5.1.13900-152 and the IMP version I am installing is 12.5.1.13900-17

Have you added IM servers on CUCM server tab?

As you did for CUCM subscriber add iM on CUCM

Agree with @Nithin Eluvathingal, have you added the IM&P node(s) in CUCM before you installed the software for CUPS?
