You have to upgrade CUPS also. In earlier versions than 12 CUCM and CUPS version had to match 5 digits from the left and from version 12 it has to match 3 digits from the left.

Hello, Harvey.  Yes you will need to upgrade IM&P to 12.5 as well.  IM&P and CUCM versions must match.

Hello, Harvey.  Here is a link to the installation guide for 12.5(1).  Take a look at Chapter 1, page 6 "Platform Requirements" and "Supported Versions".
