Abstract
A computer system includes a use state analysis program that acquires a use history of data in a first computer system and a program that uses the data; and a data migration program that extracts data that is able to be migrated from the first computer system to a second computer system on the basis of the use history, writes the migratable data to a first storage system and a second storage system, and migrates a program to the second computer system on the basis of a use history of the data used by the program.
Claims8
A computer apparatus that migrates operations having programs and data from a computer system having the computer apparatus and a storage apparatus to a migration destination computer system which has a system environment different from that of the computer system and has a migration destination computer apparatus and a migration destination storage apparatus, the computer apparatus comprising:
- a use state analysis unit configured to acquire a use history of the data in the computer system and the program using the data;
- and
- a data migration unit configured to extract the data that is able to be migrated from the computer system to the migration destination computer system on the basis of the use history, write the migratable data to the storage apparatus and the migration destination storage apparatus, and migrate the program to the migration destination computer system on the basis of the use history of the data used by the program.
A computer system comprising:
- a first computer system which is a migration source of operations having programs and data and includes a first computer apparatus and a first storage apparatus;
- and
- a second computer system which is a migration destination of the operations, has a system environment different from that of the first computer system, and includes a second computer apparatus and a second storage apparatus, wherein
- the first computer apparatus includes:
- a use state analysis unit configured to acquire a use history of the data in the computer system and the program using the data;
- and
- a data migration unit configured to extract the data that is able to be migrated from the first computer system to the second computer system on the basis of the use history, write the migratable data to the first storage apparatus and the second storage apparatus, and migrate the program to the second computer system on the basis of the use history of the data used by the program.
A data migration method by a computer apparatus that migrates operations having programs and data from a computer system having the computer apparatus and a storage apparatus to a migration destination computer system which has a system environment different from that of the computer system and has a migration destination computer apparatus and a migration destination storage apparatus, the data migration method comprising:
- acquiring a use history of the data in the computer system and the program using the data;
- and
- extracting the data that can is able to migrated from the computer system to the migration destination computer system on the basis of the use history, writing the migratable data to the storage apparatus and the migration destination storage apparatus, and migrating the program to the migration destination computer system on the basis of the use history of the data used by the program.
