Windows 2000, Exchange 2000 to Windows 2003, Exchange 2003 migration

I am looking for the best plan to migrate from Exchange 2000 to Exchange 2003. I currently have the following servers

1. Windows 2000 - DC
2. Windows 2000 - FileServer, Exchange 2000
3. Windows 2000 - Terminal Server

I am planning to keep 2, 3 servers and retire the first server eventually. I do not plan on upgrading servers 2, 3 to Windows 2003.

I have 2 new servers. One will be Windows 2003 and be my new DC. Second will be my new Exchange 2003 server with Windows 2003.

What is the best sequence and steps to implement the 2 new servers and retire the first server?

Hello gc_expertsexchange,

Upgrade Exchange 2000 to 2003

Before you start ?

1.      You will need the exchange 2003 media and a copy of the Server 2000 media
2.      Make sure there has been a FULL backup of the server you are going to upgrade AND the domain controller (you are about to change the Active Directory Schema) at the very least a backup of the information store and the system state.
3.      Make sure the user you are logged in as is a member of the schema admins group and obviously an administrator


The server that will be upgraded should as a minimum be running Windows Server 2000 with Service Pack 3 and Exchange 2000 Service Pack 3. In addition the server must at least be a member server (which already should be the case as we are upgrading from Exchange 2000)

If your environment is based on a Windows 2000 Active Directory domain, you should make sure all Domain Controllers as a minimum are running with Service Pack 3. If it's instead based on a Windows 2003 Active Directory domain, we are almost ready to start the upgrade process.
When doing an in-place upgrade from Exchange 2000 to 2003, you have to upgrade to Exchange 2003 first, then update Windows Server 2000 to Windows 2003 Server as Exchange 2000 does not run on Windows 2003 Server (see MS KB 321648 - You Cannot Install Exchange 2000 on a Computer That Is Running Windows Server 2003 for further information).
1.      Put in the Exchange CD (if it wont autorun then run setup.exe)
2.      Click Exchange Deployment Tools > Deploy the first Exchange 2003 server > Upgrade from Exchange 2000 Native Mode
3.      We're now presented with the list of the 9 required steps.

Step 1 - The server must have Service Pack 3 or later applied, if not it won't even be possible to do the upgrade.
Step 2 - We should now verify NNTP, SMTP and World Wide Web services are installed and enabled, but as we are carrying out an in-place upgrade from Exchange 2000, this step are really not that necessary as the components are already installed as they are required by Exchange 2000 as well.
Step 3 - If present we need to remove the Instant Messaging Server, the Chat and Key Management Server, the Lotus cc:mail connector and the MS Mail connector before the upgrade, as these components are no longer part of Exchange. If you want to retain these services in your organization, you should not install Exchange 2003 on servers running these components but no one stops you from keeping Exchange 2000 Servers with one or more of these components in your Exchange 2003 organization.
Step 4 - In order to complete step 5 and 6, the Windows 2000 Support tools have to be installed, these tools are included on the Windows Server 2000 CD. To install the Support Tools run Setup.exe under the support\tools folder.
Step 5 & 6 - Involves running DCDiag and NetDiag, these two tools check the consistency of the Active Directory domain and the network connectivity. If you get any errors or warnings, when running either DCDiag or NetDiag they must be resolved before proceeding to step 7.
Step 7 & 8 - The current messaging environment needs to be prepared before upgrading to Exchange 2000, therefore we have to run ForestPrep and DomainPrep, you probably remember these two preparation steps back from the days, when you upgraded the Exchange 2000 environment you have today. You even remember you actually ran ForestPrep and DomainPrep, and are now wondering why you have to run them again. The reason is the new ForestPrep and DomainPrep has been extended, and are introducing a lot more new AD objects and attribute definitions compared to what Exchange 2000 did. So running the new ForestPrep and DomainPrep tools are absolutely mandatory.
Step 9 - When you have completed all steps but step 9, you are ready to execute the Exchange 2003 Installation Wizard, therefore click Run Setup Now. The Microsoft Exchange Installation Wizard appears > click Next > put the tick in I agree > click Next.

4.      MAKE SURE UPGRADE is displayed !!

It should say UPGRADE next to

Microsoft Exchange
Microsoft Exchange Messaging and Collaboration Services
Microsoft Exchange System management tools

5.      Click Next


The installation begins, it will take a while as the Exchange installation Wizard has to go through a Pre-Installation, Installation and Post-Installation phase, so have patience (45 mins for a 7Gb mail store on a G3 ML370 1.4Ghz with 768Mb of RAM)

NOTE: Dont go have a coffee just yet you may get a message about Microsoft Search and degraded system performance during upgrade - just click OK this will be near the start of the upgrade - once done ->Brew Time :)

6.      When the Exchange Installation Wizard has completed, click Finish.

7.      The system will prompt you for a reboot - do so. (Remember if its a DC it will take some time)

Note if you stay on Server 2000 the following cannot be used

RPC over HTTP
Volume Shadow Copy

1. Should I be installing the new Windows 2003 DC before I install the new Exchange 2003 server?
2. Can the Exchange 2000 server and the new Exchange 2003 server co-exist on the same network?
3. Can the Windows 2000 and Windows 2003 server co-exist on same network?
