I would do it a bit differently, set up a new Unix domain member using
exactly the same smb.conf as your old Unix domain Member (note you
don't need to use the same hostname and you do not need to set 'netbios
name'). Join the domain (which will ensure all your users and groups
are known on the new Unix domain member) and then use something like
rsync to transfer the data.
