Maybe! I haven't tried this myself yet, but next time I need to do this
I think I'm going to take an mtree backup of the entire filesystem,
change the UIDs and GIDs (vipw, then vi /etc/groups), and then re-apply
the mtree to the entire filesystem. It should find all the files that
are now orphaned and fix them to use the new UID/GID that you specified.

Not having a backup :)
