Andrey Stepachev commented on HBASE-11987:
------------------------------------------
Checked, that on state migration all should work as expected, we will read
state, rewrite it in enabled state and then updated with what we'll find in zk.
Sounds like that should work.
> Make zk-less table states backward compatible.
