Automic Admin cannot upgrade his AWI from 12.2.1 to 12.2.6. After following all the correct steps, they get the following error when logging in:
[HTTP 404] (45109) The requested resource cannot be
found: No detail information available
Release : 12.2.x and 12.3.x
Component : AUTOMATION ENGINE
Ultimately the Automation Engine and the Automic Web Interface (AWI) have to be at the same version.
Automic Admin reverted to the awi.war file that was at the same version as their AutomationEngine.
