A-Flex-3 & Unity Cxn license addon only

[jeanie.embry]

How can you add Unity Connection licenses only under A-Flex-3 sku?

I have client currently running CUCM ver11.5 with qty-218 available Enhanced perpetual licenses; only need additional voicemail licenses.  Legacy R-CBE6K-K9 sku only allows ver12.x, no v11 addons.  CCW returns error in configuration when using A-Flex-3 sku since no Pro, Enhance, Access calling license chosen.

11.5  versions has reached EOS May 2021.  R-CBE6K-K9 sku has reached EOS, you cannot order it anymore.
