Thanks for the suggestions.

We haven't tried a full scale save restore yet, but would like to try some other
things first.  For the large scale restore to work, I think we would have to 
save
all the data files, then delete the bad files, then restore the saved files.  
This
would be like initializing your disks then restoring from tape. Kind of scary.  
If
we don't delete the files, I think they will keep the same creation date, but 
will
test this.

Another possible problem with this that if we already have multiple members, I
think it might save, then restore them in date order and just give them a new
date.  When I created duplicate objects of the GJW file, the duplicate object 
had
new dates, but the incorrect member was created first (the workstation member).

During our conversion, we tried to get all the logicals in the same library as 
the
physicals.  This includes our own logicals over the BPCS files.

Not likely.  Since we were testing on the production box, we did not set the
machine date forward.
