I'm planning an upgrade to SU4 on a HA cluster this weekend. I would like to kick off the software install this evening, and then switch versions over the weekends. The documentation isn't 100% clear on what will happen in this scenario.
On page 46 (7-2) it states ... Data migration happens only when a switch version is done from a lower to the higher version; when the switch version is done from a higher to a lower version the data migration does not happen.
What Data is this referring to exactly? Historical data only?
On the next page it states .... The administrator must not make any configuration changes to Cisco Unified CCX during an upgrade. Configuration changes include any changes that you make in Cisco Unified CCX Administration, Cisco Unified CCX Serviceability, and the User Option windows.
So, if I upload the software tonight, am I correct in thinking that when I switch versions at the weekend, historical data will be carried over and any configuration changes (reskilling, new agents, new csqs etc) will be lost ?
Also, has anyone any comments on the SU4 upgrade in a HA cluster? If you've upgraded, how did you get on?
SU3 gave us many different problems, hopefully SU4 will be smoother.
Solved! Go to Solution.
TAC advised an upgrade for a couple of issues we were having. Most importantly the telephony subsystem was going in to partial service CSCtq61132 .
What kind of issues did you experience?
How did your patch upgrade go? I am about to attempt the same thing. Any recommendations?

It went well. Took about 4 hours to do a HA cluster of a very busy contact centre. No surprises.
We were hitting quite a few bugs in su3. Most of them appear to be resolved.... so far anyway. : )
I am looking at upgrading one of my customers from 8.0(2) to 8.0(2) SU4.
I was wondering if you know if this upgrade also required an update to the clients or not?
Many thanks in advance,
Thanks very much Brian, I really appreciate it.
I presume that the clients would have required local Admin rights to upgrade the clients automatically.
Yes, it goes from 126.96.36.1990 to 188.8.131.520 see compatibility matrix:
