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.
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.
The Problem is not how to update AWI but rather when. AWI12.2.2 can't connect to an 12.0.5-AE-Server, so you have to switch - with AWI12.0.5 - aktive User and Processes first to the new AE-Node. Then upgrade AWI to 12.2.2. That works.
I found a solution.
Change the Steps in ZDU helps.Before you update AWI to new version, switch User to the now node which runs with the new Software.
Then you are able to connect with AWI 12.2 and you can finish ZDU.
