Abstract: In a data migration system (1) according to an example embodiment of the present disclosure, a load balancer (20) is configured to consolidate, in a virtual machine environment (30), transactions performed in response to external requests. Then, the migration device (10) copies, via a virtual machine environment (40), storage data stored in a storage device (50) of the virtual machine environment (30) and the virtual machine environment (40) to a storage device (70) of a container environment (60). In the case where the storage data of the copy source has been changed during the aforementioned operation, the migration device (10) makes the storage data already copied to the storage device (70) consistent with the storage data of the copy source that has been changed.

Abstract: A design management apparatus includes: a system requirement obtaining part which obtains a system requirement of a managed system configured to include a managed apparatus(es); a requested resource determination part which determines a requested resource(s) based on the system requirement; a spare resource determination part which determines a spare resource(s) by performing a fluctuation prediction on the system requirement; and a system configuration determination part which determines system configuration information regarding a system configuration including the requested resource(s) and the spare resource(s).
