A management apparatus includes a memory and a processor coupled to the memory. The processor is configured to: sequentially read data from a movement-target storage area of a storage device included in a first storage apparatus when the data stored in the movement-target storage area is to be moved from the first storage apparatus to a second storage apparatus which is accessible at a higher speed than the first storage, the first storage apparatus including the storage device and a cache memory configured to cache the data stored in the storage device using a write-back scheme; read changed data among the pieces of data in the movement-target storage area from the cache memory; merge data read from the movement-target storage area and the changed data read from the cache memory; and write merged data to the second storage apparatus.
