migration from 17.0 to 21.0 version of AWX

Hi All, Need someone assistance in on of issue I am facing while we migrate from 17.0 version to 21 version of AWX.

With controlplane instance group the runners or task container is not executing the job templates and the execution environments is also not working, the jobs just stay in pending forever. Can someone suggest how it can be solved.

Can you help us understand if the deployment is k8s based or vm based ?
If its k8s based are you using external postgres or awx provided postgres?
if its internal based postgres wat is the awx operator version ?

If its vm based(Docker Based) did you happen to run some thing like docker logs and also are using execution environments that you have compiled for 17.0 or did you compile new execution environments ?
