Smb PDC move howto?

[Patrick_Scannell at fws.gov]

What files to do I need to copy and reconfigure to move a Samba PDC to a
new machine?

Old server is smb 2.2.2 on RH7.1 with about 100 Win2K and Win98 users.
New setup is a 2 machine cluster with smb 2.2.2 on RH7.2 and heartbeat.

Other than move the contents of /etc/samba, what needs to be done to
maintain domain trust relationships etc.  This seems like it should be a
FAQ but I couldn't find anything about it.  Samba has been a dream for me
so far and I'd like to keep it that way.  Thanks,   Patrick
