摘要： PROBLEM TO BE SOLVED: To achieve data migration that eliminates the need for setting again a storage to be a destination of an access request issued by a business application when copying of data is completed.
SOLUTION: The destination of the access request sent from a business application 50 is switched from a device node 10A of a source storage 10 to a device node 20A of a destination storage 20. Data in the source storage 10 is then copied to the destination storage 20. A request for execution of a read process or a write process on the data stored in the storage, which is issued during the copying of data, is transferred to the device node 10A, and the read or write process is executed to the source storage 10. Further, when target data of the write process executed in the source storage 10 is already copied, the target data is copied again to the destination storage 20. When the copying of the data is completed, the transfer of the access request to the device node 10A is stopped.
