A storage apparatus for controlling a storage unit includes a cache memory for temporarily storing data to be stored in the storage unit, and a processor for executing a process including receiving unit data which is divided from data to be migrated, calculating first checksum data from the received unit data, storing the unit data and the first checksum data to the cache memory, reading out the stored unit data and the first checksum data from the cache memory, calculating second checksum data from the read out unit data, storing the unit data to the storage unit, and determining whether data migration has been performed properly by comparing the first checksum data to the second checksum data. |
