are you using DHCP? and net login scripts in samba? just change the
WINS server in DHCP. move over all of the .tdb files, make sure the new
server has the same domain sid. have the netlogon scipts unmount their
shares and remount them to the new server.

Hey All,
I'm pretty new to complex Samba setups, but have used the more basic
distro settings a lot over the past few years; many thanks for all the
solid code.
Anyway, where I work I'm faced with moving a samba PDC from one server
to another. The backend password database is in LDAP, so I think that
makes it easier? The current server is aging (4-5 years old) and is
low on disk space, necessitating the move. However, the old server is
still used for email and telephony, so it needs to stay on the network
with the current name (say server1.mycompany.net). I plan on turning
Samba off on this server after the migration is complete.
We've got about 25 Windows XP Pro desktops on the domain and obviously
I don't want to change anything on them. The users are accessing
shares on this server with \\server1\sharename and many have different
shares mapped in their profiles.
So I'm trying to figure out what the easiest way of getting things
onto the never server are without disrupting users? My first thought
is that, while confusing, it should be possible to just move
everything over to the new server and call it server1 (via
NetBIOS/WINS) even though it's DNS name is server2.mycompany.net?
That way all the users' mapped drives work as they should (as the name
is the same), but I hear this can cause some name resolution issues?
I suppose the other approach is to call the new samba server something
different (but of course the same domain name). Maybe even give it
the NetBIOS name of FileShare or something else service based so if it
ever has to move again the naming convention makes sense. If I went
this route I'd have to change all the users' mapped drives, and
hopefully there's a way to do this on the server side? Will the
desktops successfully login to the samba server if it's renamed?
Yet another thought is adding the new server as a BDC, moving the
share data over to it, and either promoting the BDC to a PDC or just
let them both run with the PDC serving logins but no real data. Then
if the PDC dies, I'd presume there is a procedure to promote the BDC
to a PDC?
Thanks for the help, I want to make sure I go down the right road on
this architecturally before I start hacking.

PS: I'm using Ubuntu if that helps (migrating from 6.06LTS server to
8.04LTS).
