I wan to upgrade my CUCM from 220.127.116.1100-1 to 18.104.22.16800-2.
My question is Could be able to just upgrade the CUCM and not the UNITY Connection?
Im planning to the Unity upgrade later.
any recommendation will be great
CUCM 8.6.2 is compatible with CUEAC/CUBAC 22.214.171.124. Refer page 12 of following release notes
Pls rate helpful posts !!
Depends, if you're talking about a CUCMBE 5K the answer is no, you upgrade the whole system.
If they're standalone installs, then yes.
If this helps, please rate
Yes, you can. I presume your CUC is also 8.6.
