I am running CUCM 6.1.1, and am trying to upgrade to 6.1.3. I have a pub and two subs.
I did a switch version on the pub, but when I went to login to CLI or Web, I noticed that my password had reverted to my previous password. This made me suspicous, so I looked at the data in the pub, and I was missing quite a bit of phones, device pools, etc that I created fairly recently.
I panicked, and did a switch version on the pub back to 6.1.1 and all is fine.
Has anyone seen this before? Would I have been OK to proceed with the switch version on the subs, then my data would be current?
The only thing I can think of is that I installed the 6.1.3 software on the pub a month ago or so, but did not install it on the subs until the other day. I dont see how that could explain my loss of data, but wanted to throw that out there.
