Yes, I did so once by accident, when trying to recover a lost object.
Think in terms of a large scale save of your files, then a large scale 
restore of your files, except that the job date of the restore is the date 
you want to be the recreated date of your files.

Suggest you test this first on a small scale to verify this works as I say on 
your current hardware operating system combination.

Caveat - when you do the save, also save your access paths - it takes longer 
to save, but if you do not do it, you will pay big time in the restore.

Caveat - if you can do the save & restore on system restricted, the whole 
thing will get done with greater assurance than if you have to futz around 
with coping with end users on the stuff you are trying to save.  I do all our 
saves on a restricted system to avoid erroneous error messages.  It is not 
worth the grief trying to track down what went wrong, when nothing went wrong.

Caveat - IBM needs to restore physicals before restoring the logicals over 
them.  This should not be a problem when logicals & physicals are in the same 
library & use the standard BPCS naming convention of PHYSICAL_L## for 
logical, but SSA BMRS & PTFs have a penchant for including some logicals in 
the fix-library that apply to the physicals in the main library, and the fix 
library is alphabetically before the main library.

Example BMR something something something contains a logical over BPCS 
something - now BMR is alphabetically before BPCS & if you are using an IBM 
restore with defaults, the contents of libraries are restored in alphabetical 
sequence of library names, and this can be a suicide mission if you are not 
aware of logicals inside the BMR that point at physicals in the BPCS.

We converted to BPCS CD last year & did not have this problem.  Is it 
possible that someone on your conversion team was testing Y2K dates & did not 
get reset back to contemporary date when doing something else?
