You can use find for your opinion:
find /path/to/your/restore/ -uid 1021 -exec chown newuser.newgroup {} \;
set both, the new uid and the gid
or
find /path/to/your/restore/ -gid 1022 -exec chgrp newgroup {} \;
set only the new gid
... or whatever witht find ... -print0 xargs .... This is not a native restore
problem, i mean this is only a admin job for the local operator.
