I'm facing version upgrading of CUCM & CUC from 10.5 to 12.5 , also deployed IMP in this environment , shall I also have to upgrade d IMP to 12.5 ? or can keep running 10.5 ?
Thanks in advance
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".
