When upgrading a UC appliance, is the database upgraded during the upgrade or the the switch?
We are upgrading all servers for a customer (6x CUCM, UCCX HA, CUC...) from 8.0 to 9.x and moving them from MCS to ESXi on UCS.
The CUC has an ES that nobody can find so i have to upgrade the CUC ES to a 8.5 version just above the ES version. But yesterday i discovered that the CUC has an upgraded inactive partion.
If the database is converted during the installation of the upgrade i have to to the upgrade then switch. But it the database is upgraded during the switch i only have to do the switch.
