Hello,

I have a windows 2000 server network now. I am looking to upgrade to windows 2003 server & upgrade my hardware. Because the hardware will not run windows 2003 server. I want to keep running the windows 2000 server network & build my windows 2003 server network. Then I want to slowly move users over the the Windows 2003 network.  How do I do this???

Thanks for all your help..

can be done quite easily with a clean install of the new server

**Note - If introducing a 2003 R2 Server into the network as a DC you will need to run the ADPREP tools from the second cd

\CMPNENTS\R2\ADPREP

you can also download here
http://www.microsoft.com/downloads/details.aspx?familyid=5B73CF03-84DD-480F-98F9-526EC09E9BA8&displaylang=en

this boosts the schema up to cope with R2 functionality
http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.mspx

1) Promote your new machine as an additional domain controller in an already existing domain - this will allow AD to replicate to the new server
2) Make sure DNS is AD integrated on your old DC to allow all DNS replications also
3) Transfer the FSMO roles to the new server
http://www.petri.co.il/transferring_fsmo_roles.htm
http://support.microsoft.com/default.aspx?scid=kb;en-us;255690
4) Make the new DC a Global Catalog under Sites and Services
http://support.microsoft.com/?kbid=313994
5) Deactivate DHCP on the old DC (if used) and recreate the scope on the new DC, note if you have a fairly complex or Large DHCP scheme you may want to export and import the database
http://support.microsoft.com/kb/325473/
6) Run DCDIAG to make sure all is well and replication is fine
7) Demote the old DC if you dont intend to keep it as a backup
8) Recreate Shares etc on the new server
9) Reinstall printers and share them etc....


this will allow you to have the complete AD directory on the new DC and clients will barely be aware of any changes

Hi berniem1980,

Quite simply,

Add the new server with windows 2003 to the domain (as a member server)
Prepare the domain for windows 2003 (with adprep)
Then upgrade the new server to a Domain Controller
Once the new server is a DC, it will automatically have a copy of the domain information (and you can begin getting rid of old servers)

More information?  Do you have Exchange on the network?  Because that can add a few more steps

Hope that helps,

-red

I want to set this up like a new network no replication or anything. Start from the bottom up.

in that case, a basic overview

build your network, create trusts with your old network and migrate your users.....

I am assuming no exchange here, if you have exchange then Red is your man

If you are going to use outlook, then Exmerge would be the best way to go - it will rip all your mailboxes out to PST files

you can do an migration or just add this new
DC as an replica and move master operation roles, install exchange move
mailboxes and keep the current AD, and then demote the current DC or may
keep it.

How ever if you want to migrate you may want to restructure the
Active Directory. You can use the tool ADMT you will find more information
below.

326480 - How to Use Active Directory Migration Tool Version 2 to Migrate
from Windows 2000 to Windows Server 2003
This article describes how to set up the Active Directory Migration Tool
(ADMT) to migrate from a Windows 2000-based domain to a Windows Server
2003-based domain.

I read this link about trust but did not have anything on how to set them up. Is there any instruction on how to set a trust between a 2000 & 2003?
