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.
It refers to all data, basically if you do the upgrade but not switch for few days all new configuration and historical data will be lost after you perform the switch.
