We can not be able to roll back to previous releases. Only be able to restore previous releases from the backups.
What is the procedure to do this backup restore?
→ Is replacing the backup IS instance folder with the 8.2 instace folder is enough?
→ Or have to follow any other procedure?
Yes,but you should ALWAYS check with SAG support on rollback procedure (101% works) instead of messing whole IS instance folders.As an alternate use the OS backups for full restore.
