It may actually be easier to move everything including hostname and IP to
the new server and just shutdown the old (this would have to be off hours.)
You should be able to do the following-
- Configure the new server as a BDC. I don't know for use if you can
configure a BDC with a TDB backend- if not you may have to make the new
server a PDC.
- Copy the samba private directory (with the tdb files) from the 1st
server to the 2nd server. In effect, this temporarily syncs the two
- promote the new server to PDC and the old server to BDC.
- after hours- move the shared directories to the BDC, update login
script if necessary.
Clients will connect to either a PDC or a BDC for authentication.- it
doesn't really matter that much except that clients will prefer a BDC if
Once you take the OLD server offline you may need to have clients reboot to
have them use the new server for authentication. But at least domain
membership will not be broken?
Are you using a WINS server?

Subject: [Samba] Samba migration to a new server
Is it possible to migrate Samba to a new server without breaking Domain
membership of all the clients ?
I didnt get any info on that issue, is there someone that has previous
experience of doing that ? Or maybe a link to some relevant info ?
I have currently a Samba 3.5.6 server that acts as a PDC and print Server,
with tdbsam backend, no LDAP at all, no roaming profile. I have to migrate
samba to a new server. Everything (Samba release, Domain Name, shares, ...)
will remain the same except for the DNS name and IP address of the server,
and the samba server netbios name.
What is the best way to proceed to make this migration as seamless as
possible for all users (more than 200 user accounts with more than 200 PC in
the domain) ? I guess that just moving all the samba configuration files
from the old machine to the new one will not be enough.
Thanks in advance. I really need your help.
