ABSTRACT:
A method of migrating a computer system between a virtualized environment and a non-virtualized environment comprises configuring one or more storage volumes for a migration destination in a destination environment based on a migration request containing a backup requirement specifying one or more copy groups, each copy group including storage volumes that store data for at least one of a virtualized device and a non-virtualized device; converting and migrating data from a migration source in a source environment to the one or more configured storage volumes of the migration destination based on copy group information of the one or more copy groups, one of the source environment and the destination environment being a virtualized environment, and another of the source environment and the destination environment being a non-virtualized environment; and migrating backup unit/group information by replacing copy group information in the source environment with copy group information in the destination environment.
