Abstract
Described embodiments may provide systems and processes for migrating a replica hierarchy from at least one source device to at least one target device in a storage system. A configuration of the replica hierarchy is migrated, one or more internal nodes of the replica hierarchy are migrated, and one or more leaf nodes of the replica hierarchy are migrated. A cutover operation is performed by deactivating the at least one source device associated with the included replica hierarchy.
