Provided is a management system for a storage system, the storage system including a first storage subsystem and a second storage subsystem each including logical storage areas for storing data to be processed by a host computer, the logical storage areas in each of the first and second storage subsystems having storage tiers associated respectively with a plurality of storage area characteristic information pieces which are information pieces characterizing the corresponding logical storage areas and which are different from each other, the management system comprising a data migration management part, wherein when the data is migrated from the first storage subsystem to the second storage subsystem, the data migration management part: acquires a configuration of the storage tiers of the logical storage areas of the first storage subsystem in which the data of a migration target is stored; compares the configuration with a configuration of the storage tiers of the logical storage areas of the second storage subsystem; and then migrates the migration target data stored in the logical storage areas of the first storage subsystem to the logical storage areas of the second storage subsystem in accordance with a result of the comparison. |
