We are moving from 3390 to 3390, so I plan on using DDR to move the volumes containing ordinary spool files but just format and allocate the disks specified as DUMP. I can do the format/allocate while the system is running. My aim is to minimize the downtime, even if it takes more work to do so. I do want to avoid using SPXTAPE. We usually have 10s of thousands of spool files and no high-speed/high-capacity tape drives, only a couple of them, so tape I/O is not at the top of our desirable things list.

I ran ICKDSF and CPVOL to format then CPVOL to allocate, the spool and dump volumes, IPLed CLEAN from the DDRed RES volume, and did a SPXTAPE load of the spool files.
