> In Move currently we take any destination specified and if the destination is same as
the source we still do unassign and assign.  Here we can have problems due to RegionAlreadyInTransitionException
and thus hanging the region in RIT for long time.  We can avoid this scenario by not allowing
the move to happen in this scenario.
