ABSTRACT:
Provided is a method and system for performing volume migrations while retaining persistent point in time data of the migrated volume. Specifically, by using a collective persistent point in time data map that describes a collection of persistent point in time data of a volume to be migrated, the collective persistent point in time data map and volume data can be migrated during a quiesced period of user activity. Then, during a non-quiesced period of user activity, the persistent point in time data can be transferred to the location of the migrated volume in real-time.
