Please check guide -
Let me know if anything else.
I already have this guide and checked it before I have posted but I did not get my answer about required steps before the migration
A few housekeeping activities i would do before I apply CSM package to target pod -
source & target pods are on the same patch level (e.g. release, CWB)
publish/delete sandboxes on source & target pods
if workspace migration is included, ensure workspace publish is not run on source & target
Okay so I have to make sure there no any object is locked and what about check users login ?
