Abstract
Examples described herein include a data migration system for migrating data between different data storage environments. The data migration system creates a first volume on a first storage system, and creates a logical unit within the first volume. The data migration system then creates a virtual volume on a virtual storage system associated with a second storage system, wherein data stored in the virtual volume is backed by the logical unit on the first storage system. The data migration system then replicates, on the virtual volume, a set of data stored on the second storage system. Upon replicating the set of data onto the virtual volume the virtual storage system may automatically create a copy of the corresponding data in the logical unit of the first volume.
