You could try
update rdb$functions
set rdb$module_name='udflib'
where rdb$entrypoint='fn_whatever'

Be sure that you get the case correct for the positioning criterion, i.e.
as it was declared in the original database, since rdb$entrypoint is a
char(31).

You'll need totally exclusive access and no GUI admin tool running, that
queries the system tables. Use isql locally. Remember to shut down and
start up the server afterwards.
