When a migration object is a stub file, a data migration apparatus, which migrates data from a source HSM execution environment to a destination HSM execution environment, reads data from source secondary storage based on a data storage address in the source secondary storage. This data storage address is stored in the stub file in source primary storage. The apparatus writes the data into destination secondary storage according to a rule for storing data and reads attribute information on the stub file stored in the source primary storage. The apparatus creates, in destination primary storage, a stub file having the same name as in the source and, according to the stub file generation format in the destination primary storage, supplies the address of the data stored in the destination secondary storage and attribute information acquired from the source primary storage to the created stub file to complete the data migration. |
