Abstract: A storage system comprises a second NAS storage apparatus comprising a processor and a storage medium and a third NAS storage apparatus for migrating an object managed by a first NAS storage apparatus. The processor stores path information of an object for which migration has started after including the path information in object management information, in the storage medium prior to migrating the object entity to the third NAS storage apparatus. The processor, after receiving the object entity from the first NAS storage apparatus and migrating the object entity to the third NAS storage apparatus, stores the third NAS storage apparatus path information to the object entity in the object management information, and reflects the management information in the third NAS storage apparatus.
