Abstract
A computer system and a storage migration method capable of simplifying the migration process of a storage apparatus while avoiding the performance degradation of the overall system. A management apparatus for managing data migration from a first storage apparatus to a second storage apparatus is provided. The management apparatus acquires apparatus-specific information of the first storage apparatus from the first storage apparatus and notifies the acquired apparatus-specific information to the second storage apparatus, and the second storage apparatus sets, as virtualization information, the acquired apparatus-specific information of the first storage apparatus notified from the management apparatus to a path connecting a second storage area and a second port associated with the second storage area in the second storage apparatus, and notifies the virtualization information as its own apparatus-specific information to a host computer in response to a configuration information acquisition request from the host computer.
