[Samba] Windows 2003 AD (2003 level) Replacement

[Garth Keesler]

It's been well over a year since I tried doing this and, at that time, 
it was not a simple install. File replication didn't seem to work, some 
accounts didn't show up in the new server, and the internal DNS seemed a 
bit problematic.

The goal was to decommission a 2003 AD server (2003 level) and replace 
it with Samba4. Exchange 2000 exists in this domain but not much else.

I have occasionally checked to see if it has become a simple process of 
moving FSMO roles and demoting the 2003 AD server but it's not clear 
from the forum or the docs.

Has it become that simple or does it still require a fair bit of 
fiddling around to make it work?

Thanx,

Garth
