Do you mean on the BSD machine?
There should be no problem _if_: 
  The UID & GID do not conflict with another existing user or group.
  You get all of the incidences of the use of that user's UID & GID
  changed on all of that user's files.

But, if it conflicts or you miss some files somewhere, it can
come back and bite you.   Use find(1) with -group and then with -user
to look for the files.
