Or two DSs at the parents: the old and the new one. Only the new NS-es.

Note that if the uncooperative party puts a long TTL on both the NS  
and the security records a client may be retrieving old records for a  
very long time. In that case the new party may actually force  
validation failure for the old parties. Depending on how much harm the  
old party does.
