> 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.
