Franz Josef, If you move your production SPOOL to dedicated volumes, along with your WARMSTART / CHECKPOINT areas then, unless the format of the SPOOL control blocks changes (a rare occurrence and one which is always flagged in the documentation when it happens) you shouldn't need to restore the SPOOL files. (Of course, I'd always advise taking a SPOOL backup - "just in case" but, with a separate SPOOL configuration I wouldn't expect / plan to need to use it!)
Regards Jeff (P.S. Whenever I've had influence over such things I have always modified COPYFILE to default to OLDDATE - it's saved my bacon on several occasions!)
