Most toolstacks receive the incoming migration into a domain named
FOO-incoming or some such and then rename to FOO upon completion. Some
also rename the outgoing domain "FOO-migratedaway" towards the end so
that the bits of the final teardown which can safely happen after the
target have start can be done so.
