Hello,

KeyHelp : 26.1.1 (Build 3698)

Please Update your KeyHelp to version 26.2 first - there was a KeyHelp update recently.
After your updated KeyHelp, the upgrade script will run without problems.

This instances was upgraded 5 minutes earlier from D11 => D12

Just finished the reboot, this is what i got, and i don't want to stop here, just going forward.

I will test this tomorrow morning, the systems need to run in working hours.
