Running Call Manager on an unsopported hardware

[luismgallop]

Hello experts, 

We would like to know what could be the potential issues of having a CUCM cluster running on an unsupported server based on someone else's experience. We detected a customer with CUCM cluster (1Pub and 2 Subs)10.5 running on a UCS M5 for a few months now, while they complete the buying for the 12.5 licenses (Delay due the covid19), which should be done within the next few months. Right now, we just want to make sure we understand the possible issues they might face while the upgrade is completed. 

Also, they have CUC and IMP.  CUCM cluster size is about 1200 phones.

Hi Luis,

Your are on your own, basically is this. You may have issues or maybe not.

If you're a partner get in touch with pre-sales team to get all the informations.

What's the specific issue with the hardware?   It was a special case, but I once had a customer running Unity Connection on hardware that was unsupported for his current version, but supported for the version he was upgrading to.  I had a response from TAC saying they would support the upgrade process on that hardware (of course in the event there was no issue).
