[Samba] Copy usernames and passwords to another machine

Your 2 Samba servers are file servers only? No AD nor NT4 domain?

If they are both file servers you would need:
- Samba installed on both server, same configuration as a start (could of
course be changed later)
- Same users defined in system side (copying your users lines from
/etc/passwd and /etc/shadow from working file server to the new one. Don't
copy services accounts - as ssh, postgresql...- nor root account, just
Samba users lines).
- Same Samba database on both servers. Here you have to find on your
working file server where is stored that database, I have no idea about

Once all that is copied from your working server to the new one both should
work identically (except for shares where paths or files could be missing).

That's just an idea, I didn't tested that.
