Hello all, I planning out an upgrade of CUCM 8.5.1 and CUC 8.5.1 to 10.5 for both.
We have a CUPS server that is on version 188.8.131.5200-49 however, I don't think that its covered under our UCSS so it looks like I can only upgrade CUCM and CUC.
Does CUPS need to be upgraded as well or can I stay on CUPS 8.5.2 without any issues? I have little stick time on CUPS so I'm not even sure how it integrates into CUCM.
Starting with versions 9.x and above, CUCM and IM&P are more and more integrated, no more mix and match, and compatibility is as easy as it gets, they both need to be in the same major release up to the x.y version. So, to answer your question, no, it's not compatible and not upgrading CUPS to IM&P, is not an option.
