Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a computer device, a computer system, and a data migration method capable of automatizing the data migration required for a migration.

SOLUTION: A computer system has an usage state analysis program 122 to acquire data for a first computer system 10 and an usage history of the program using these data, and a data migration program 123 that extracts data capable of transferring from the first computer system 10 to a second computer system 40 based on the usage history, writes migratable data to a first storage system 200 and a second storage system 500 respectively, and moreover, migrates the program to the second computer system 40 based on the usage history of the data used by the program.
