Hi there,
I am planning a PCD based migration from CUCM/IMP 12.0 to 12.5. Previously while doing in place upgrades (non-migration), I used to disable the High Availability under Presence Redundancy groups on the CUCM, as per the upgrade guide. However I cannot find the same direction while reading the guide's migration option. I wonder if it is okay to keep it on during the migration? Whats your experience? Thx!
