Hmmm.... It's been my experience that BACKUP preserves most data quite well;
in fact, IBM even makes *new*format* RESTORE programs COMPATIBLE with *old*
BACKUP formats!

I also generally find that upgrade time (such as 3.3 to 4.0) is also a good
time to reorganize directories, etc. which, by the way, BACKUP and RESTORE
do quite SAFELY... slowly, for sure, but safely.
