I am upgrading a UCCX 7.01(SR3) system to UCCX 8. They are equipping HA over the WAN as well. They have bought two new servers for this, and the customer would prefer to have the system installed in parallel for a day or two, and then move to the new servers in production. I have been reading the install/upgrade instructions and it seems like the Pre-upgrade-tool backup is a comprehensive on (configs and historical database). In this case I could not to the upgrade on the new server while the old server was still in production. But if I build it as a fresh install, then I will lose my Historical Reporting Data. Also, if I do a fresh install rather than an upgrade, will I lose my current licensing?
I know this is a new procedure for most here (me included), but I was hoping someone might have an idea as to how I might be able to accomplish this. Is there a way to save just the historical data, like the old data migration?
