without stopping the resource. Virtual IDs are information about the old storage system, and are set
on the migration-destination resource. In Device Manager, you can check virtual IDs after data
migration and perform operations on a resource that has been assigned virtual IDs. Until the migration
of the data of the target resource is complete, even if you can view the resource's virtual IDs, you
cannot perform operations on the resource.
For data migrations using virtual IDs, the resources that can be operated by using Device Manager
are as follows:
• Before data migration (operation using physical IDs)

be performed on the resource by using Device Manager.
• During data migration

the migration-source resource. On the migration-destination storage system, while the attribute that
