If you are using the same spool volumes and they are defined in the same

areas, then you should be able to shut down your old system and IPL the
new one with a warm start and have all of your spool files restored.
Of course, it's always a good idea to back them up before shutting down
"just in case".
Backups ? Blah ! backups are for the weak ! real sysprogs now by heart
the exact contents of all their CP Owned volumes and can reconstruct
them from memory using a 3880 MD device to reconstruct the 3380 volumes
from scratch..
Now, more seriously..
Performing a DDR on a live system (or at least its CP owned vols) and
IPLing on a restore of those is going to ask for a CKPT or FORCE start..
and those spool files that were opened during the DDR process may
contain a bit of funny data ! So maybe SPXTAPE followed by a restore, a
cold start and a SPXTAPE LOAD would be a slightly better idea ! (Since I
believe the problem wasn't the actual migration - but a rollback option).
Then again, even for a migration.. keeping a SPXTAPE reel may always be
helpful.. just in case something goes awry.. (Sorry.. I'm from the SP
and XA days when thing would sometimes indeed go awry !).
