Ethan Rose updated HDDS-14754:
------------------------------
Description:
OM Prepare for upgrade will be a no-op once ZDU is supported. There may be
leftover state in the DB and VERSION file indicating that the OM was put in
prepare mode in the prior version. We should remove this state in an upgrade
action tied to OM version 100 (ZDU support) which will run when the OM is
finalized.
Similarly, SCM will not longer have a finalization-in-progress marker in its
DB. This should be completely cleared out by the old version when SCM finishes
finalizing, but we can also add an upgrade action to ensure it is removed.
