Ah, well in that case, I think it is just a case of setting up samba4
just like the samba3 machine and then syncing the userdatebase etc from
the pdc to the bdc. This is usually just done by copying the samba
directory from one to the other (on Ubuntu this is /var/lib/samba YMMV).
Start up the new machine, make sure everything is ok and then stop smbd,
nmbd, winbind on the old pdc and everything should just work, or maybe
not. If it doesn't work, restart smbd etc on the original pdc and you
should be back to where you were, you can then check the logs to try and
find out what went wrong.
This is all from memory, it is a good few years since I last did this
(ok, in fact I only ever did it once ;-) ), so if anybody has a better
way, please chime in.
