Should I upgrade my 2000 DC to 2003 or do a Migration to my new server.

Posted on 2006-03-22

I have a Windows 2000 SP4 DC with Exchange 5.5. We just bought a new server running Windows 2003 w/Exchange 2003 software.

Sould I upgrade my server to Windows 2003/Exchange 2003 or just to a migration from the 2000 DC/Exchange 5.5 to the new 2003 DC?
The 2000 DC is just used for AD, DHCP, Email and file shares. We have about 100 user using the Windows 2000 DC.

We need to return the old 2000 DC to the leasing company. This is why we bought the new server.

I if I do upgrade my 2000DC/Exchange 5.5 to 2003 How can we then do a migration from the old server to the new server?

We would like to be able to use the same domain name on the Windows 2003/Exchange 2003 DC.

I have 2 days to complete this upgrade.

Thanks in advance.

    Are you using Small Business Server in either case?  If so, you're going to have to do a migration that could be messy.  If NOT, Then I'd read over the links below regarding upgrading the domain to 2003.  Then run DCPROMO on the 2003 server making it a DC, transfer the roles, and then migrate the exchange mailboxes over to the new server.  IF you're NOT using SBS at all, then this should be a relatively painless process.  If you are... well... you're best off NOT keeping the same internal domain name, then it won't be TOO bad.

    Here are some links that should get you going for upgrading a 2000 domain to 2003:

    Quote from the top of this article: "Several glossy Microsoft presenters have stated that all you need to do to complete a Windows 2003 Domain upgrade is run ADPREP and then upgrade away.  This may work for very small / simple environments but it is definitely not good advice for most companies.  After upgrading five servers in two unrelated domains and installing many fresh copies of 2003 I can say that I personally would not skip a single step in the process I have developed below."
