I'am upgrading a AE 12.0.5 system to AE 12.2.2 via ZDU. DB-Load was OK. I have two Automic-AE-Server and the second one is upgrades to an 12.2.2 und up and running as discribed in ZDU Step 2. The first one is remaining at Version 12.0.5.
Now - in Step 3 of ZDU - I upgrade AWI from 12.0.5 to 12.2.2 successfully.
But:
I try to Login to the AE-System to finish ZDU-Upgrade and I get during Loginprocess following error:
Incompatible AE version '12.0'. Expected: '12.2'
Before I start this upgrade I ask CA, if it is possible to do such an upgrade with ZDU 12.0.5 to 12.2.2 and I get the answer yes.
