Also this option provided by chown can be useful when remapping uid or gid:

--from=CURRENT_OWNER:CURRENT_GROUP
              change  the  owner and/or group of each file only if its current
              owner and/or group match those specified here.   Either  may  be
              omitted,  in  which case a match is not required for the omitted
              attribute.

That said, find can give you more flexibility.
