[Samba] Samba migration to a new server

Hallo, henri,

My usual way:

- copy/overwrite "/etc/samba" to the new machine
- copy/overwrite all user account and all machine account informations  
(especially in "/etc/passwd" and "/etc/shadow") to the new machine

- Stop samba on both machines
- Shut off all Clients (that may be a bit neurotic ...)
- start samba on the new machine

- Start one client for testing

- if ok: start the other clients

Last friday a colleague and I have done these steps once more,  
successfully.

Viele Gruesse!
