  • migrating one or more volumes from at least one source device to at least one target device in a storage system;

    determining a discovery state of one or more of the migrated volumes by one or more host devices in communication with the storage system by;

    configuring an initiator group for each of the one or more host devices;

    sending at least one inquiry from each initiator group to each of one or more volumes of the at least one target device; and

    tracking responses to the at least one inquiry from each volume of the at least one target device;

    receiving a selection of one or more of the migrated volumes to include in a cutover operation, the selection based at least in part upon the determined discovery states; and

    deactivating one or more volumes of the at least one source device associated with the included volumes.
