Tests if the controller should be preventing metadata updates due to being in the PRE_MIGRATION
state. If the controller does not yet support migrations (before 3.4-IV0), then the migration state
will be NONE and this will return false. Once the controller has been upgraded to a version that supports
migrations, then this method checks if the migration state is equal to PRE_MIGRATION.
