Upgrade a Windows 2000 Domain to Windows 2003

We will upgrade our Windows 2000 single domain to Windows 2003.
We have one Win 2000 Server acting as a DC and one Win 2000 Server with
Exchange.
We want to make a fresh installation off the Win 2003 DC, but make an
upgrade of the Exchange Server. This to be able to make the C partition
larger on the DC.
My question is if there will be any problems to add the Exchange Server to
the freshly installed Win 2003 server acting as a DC?
Which steps must I do to make everything work as it should?

Hi Stefan,

Microsoft has a good step-by-step guide on how to upgrade Windows 2000 to
Windows 2003 domain.

Upgrading Windows 2000 Domains to Windows Server 2003 Domains
http://www.microsoft.com/resources/d...n_overview.asp

In general, you have to prepare the forest and domain (adprep /forestprep
and adprep /domainprep) and then run a dcpromo on your new Windows 2003
server.

Pay special attention to this part of the guide...

Windows 2000 Forests That Contain Exchange 2000 Servers

Before you remove Windows 2000 domain controller make sure that you move all
FSMO roles and global catalog to any new domain controller.

You might also want to move DNS server to your new server. In this case
don't forget to update your clients with new preferred DNS server or change
the settings in DHCP.

To migrate Exchange, you would do a clean install of Exchange on your new
server and then use Move Mailbox tool to migrate them to new server.

Note: personally I am not a big fan of having Exchange and Active Directory
on same server. If you need to do a restore of your server (or AD or
Exchange or whole server) it will only complicate things for you.
Another note. Have at least two domain controllers for each production
domain.

Feel free to post back with any additional questions that you might have.

I hope this helps,

Hi Mike!

And thanks for your reply.
I don't know if I explained our situation clear enough.
We have 2 servers with Windows 2000 today, and one off these with Exchange
Server and the other act as DC with AD.
I plan to keep using these actual servers, but I want to upgrade them to Win
2003.

My hope was that I could do an in-place upgrade from Exchange Server 2000 to
2003,
and after that upgrade Win 2000 to Win 2003 for this server.
It is only the Win 2000 server acting as DC with AD, I want to make a new
installation for.
I have found a lot of info about the in-place upgrade from Exchange Server
2000 to 2003,
and it seems like a rather easy process to upgrade this Win 2000 to 2003
afterwards.
My worries is about how I should get the freshly installed Win 2003 DC with
AD to operate properly
as the only Domain Controller in the domain and to make the upgraded
Exchange 2003 server to
work properly towards this DC.

Best regards
Stefan

Stefan,
I know you need to update exchange to exchange 2003 before you update the
OS to windows 2003. I just took the Exchange 2003 class.

It sounds like you want to add a new domain controller with the new
hardware. You can add a windows 2003 domain controller to a Windows 2000 AD
domain. Run adprep/forestprep and adpep/domainprep first. Install W2k3 on
the new box, and run dcpromo. Join the existing forest/domain. The move all
5 fsmo roles to the new domain (see my blog) and run dcpromo on the W2k DC
to demote it and remove it from the domain. Then do your Exchange piece like
you planned.

Note: Its always a good idea to have more than one DC for redundancy. Keep
that in mind.

Hope it helps......
