Abstract:
1. An apparatus for performing data migration of an information processing device having a plurality of storage areas, comprising: a memory configured to store a migration plan including a storage area of a migration source and a storage area of a migration destination as a task in a task management table; and a microprocessor configured to execute the migration plan, wherein the microprocessor is configured to: obtain information related to a storage area of a migration source and a storage area of a migration destination; obtain a copy speed from migration history information when there is migration history information which shows migration history from a same or similar storage area with the storage area of the migration source to the same or similar storage area with the storage area of the migration destination, and calculate a data migration time required for data migration by dividing a size of data which is migrated from the storage area of the migration source to the storage area of the migration destination at the copy speed; and indicate the calculated data migration time associated with an identifier of the task.
