Correct. Once we merge this one I will close #2159. I am still testing the migration scripts. I will comment once I am done.

[l0rd]

I have updated the scripts but for some reason Che is unstable after the migration:

• The devworkspace controller fails to start with the following message (but that can be fixed removing the devworkspace-webhook-server deployment, mutating, and validating webhooks as described in the doc):

msg":"failed to setup webhooks","error":"conflicting webhook definition found on cluster, webhook mutate.devworkspace-controller.svc clientConfig points at namespace openshift-operators"

• Posgres pod fails to restart too with the following message:

waiting for server to start....2022-03-31 23:42:43.576 UTC [27] LOG:  redirecting log output to logging collector process
2022-03-31 23:42:43.576 UTC [27] HINT:  Future log output will appear in directory "log".
. stopped waiting
pg_ctl: could not start server
Examine the log output.

That may be related to the fact that I have tested the migration with some running workspaces. I will continue the investigation on Monday.

OK. Merge when it's tested successfully.
