After the upgrade of on premise DX APM 21.3 HF1 to the DX APM 22.1 version, we found that acc PODs are not starting.
When we check the deployment, we found that the acc deployment images are still showing older version.
Release : 22.1
We scale down/up the acc deployment. We found that in the master admin UI, there is option to upgrade the acc. We selected this upgrade option. After few minutes it seems like acc version upgraded to 22.1. We see acc PODs started and we can also able to open the ACC UI.
