from disk to tape, restore data from tape
to disk, and copy data between like disk
drive volumes. You cannot use DDR to
copy data between disk devices with
different track formats.

and files between devices with identical
track formats.
v VSE ditto command to copy files.
v VSE power command to transfer the
spool queue from one device to another.
v VSE REPRO or EXPORT/IMPORT
function to move any VSAM data set.
Data migration from a UNIX-based host system to a DS8000 storage
unit
For UNIX-based host systems, you can use a variety of methods for copying or
moving data from one disk drive to another.
The UNIX-based host sees the storage unit as one or more generic DDMs. You can
use the following methods to migrate data to the storage unit from open-system
hosts that are running UNIX:
