Abstract
A system according to one embodiment, includes one or more source volumes on a source storage subsystem from which data is copied in first copy services relationships, the one or more source volumes being accessible to an application; one or more original target volumes on an original target storage subsystem to which data is copied in the first copy services relationships; logic configured for selecting a new target storage subsystem to replace the original target storage subsystem; logic configured for creating second copy services relationships between one or more new target volumes on the new target storage subsystem and the one or more source volumes on the source storage subsystem using multi-target functionality; and logic configured for terminating the first copy services relationships after all of the second copy services relationships are full duplex.
