Switching Versions

[Jeff Martin]

I upgraded my CallManager from 8.5.1 to 9.1.2 over the weekend, I learned on Monday about an incompatability between CUCM 9.1.2 and UCCX and need to revert back to my previous 8.5.1 install. I know that the jump from 8.5.1 to 9.1.2 is a big one so I wanted to make sure there were not any "gotchas" and that all I needed to do was a switch version back to the inactive partition.

Hi Jeff,

We have been doing the switch version change in the past for Call manager till version 8  but never faced any issues.

Practically , never done any rollback from version 9 to 8 .

Are u running this setup in production?

Hi Jeff,

+5 to my buddy Aman Here's a little add-on info.

If the upgrade was not on a 7825H3 or 7828H3 you should be good

to go. The steps are in the link below

Jeff,

Out of curiosity, what incompatibility did you find between CUCM and UCCX? Thanks!
