Windows 2000 SBS to Windows 2003 Server Migration

[Nicholas]

Hi, please could anyone give me their input. We are migrating from Windows
2000 SBS to Windows 2003 Server and we need to re-install our Active
Directory Controller/DNS Server from scratch with Windows 2003 Server.

We plan on taking the following steps to get move over to Windows
Server 2003:

1. Run adprep on the Small Business Server 2000 GC to prep forest and domain
for Windows Server 2003
2. Install Windows Server 2003 on a new temporary machine and run DCPROMO to
promote the server to an additional controller for the domain
3. Change the GC role and the FSMO roles to point to the new temporary
server
4. Run DCPROMO on the old Small Business Server 2000 to demote it to a
member server
5. Shut down the machine
6. Remove the SBS 2000 Server from AD Sites and Services
7. Format the SBS 2000 Server and install Windows Server 2003 on it
8. Run DCPROMO to promote to an additional controller for the domain
9. Take over the GC and FSMO roles
10. Shut down temporary server
11. Remove the temporary server from AD Sites and Services

I need advice on how to move over the DNS to the temporary server during
this whole process - otherwise after Windows 2003 Server is re-installed on
the main controller, we wont be able to promote it and get back the AD from
the temporary server.

Do you suggest I create a secondary DNS server on the temporary server using
the procedures described in this MS article:
http://support.microsoft.com/default.aspx?scid=kb;en-us;313563&Product=win20
00

Theoretically, that would copy all the dns zones and settings required by
active directory to the new server from the old controller which we want to
re-install.

Thanks

Hi,

Assuming your DNS is Active Directory Integrated, you shouldn't have to do
anything beyond installing DNS on the 2003 box. You'll need to update your
DHCP scope so that clients point to it during all this too. If the zone is
not active directory integrated (in your scenario it should be), follow the
steps in that KB, and then once everything is transferred over, convert the
zone to a primary.

Your planned course of action looks good.
