One of our SQL Servers updated to version 12.2 even though the license is only valid up to 12.0. This resulted in several backup jobs failing overnight as this converted the installation to the free edition. I downloaded the installer for v12.0, installed it, and now it won’t launch.
I’m sure I’ll figure all this out, but it’s work that shouldn’t be necessary. I suggest that auto update not update past the license. Right now we are updating our SOP to disable updates on all new installations going forward.
