Exemplary methods for data migration from a first storage system to a second storage system include maintaining a database containing deduplication information associated with a plurality of remote target storage systems. In one embodiment, the methods include identifying a plurality of storage devices of the first storage system as candidates to be migrated to the second storage system based on access patterns of the storage devices at the first storage system, and selecting one or more storage devices from the identified candidates to be migrated to a second one of the plurality of remote target storage systems that is selected based on the deduplication information of the database. In one embodiment, the methods further include migrating one or more datasets stored at the selected one or more storage devices to the second storage system.
