Isn’t it fun when it comes time to upgrading server hardware, especially when you need to upgrade your first installed domain controller and exchange server to a new server? Even though its not a guaranteed flawless procedure, Microsoft has done a great job improving the migration in Server 2003. In most scenarios, you’ll want to keep the same server name. So, you’ll need an intermediate server to assist with the process.
- Determine which server you’ll use as an intermediate server. Set the server up with Windows Server 2003 and Exchange 2003 (if needed).
- Migrate the Exchange 2003 mailboxes from the existing domain controller to the temporary domain controller (http://support.microsoft.com/default.aspx?scid=kb;en-us;821829)
- After all mailboxes are moved over, begin transferring the domain controller and Active Directory roles (http://support.microsoft.com/default.aspx?scid=kb;en-us;255690)
- After all roles are migrated to the temporary server, migrate the Exchange server roles (http://support.microsoft.com/default.aspx?scid=kb;en-us;152960)
- Test to be sure client computers can connect to the temporary server. If they can, repeat these 5 steps again, but with the temporary server and the new domain controller.
If you need to uninstall Exchange for any reason, use the following Microsoft Knowledge base article: http://support.microsoft.com/default.aspx?scid=kb;en-us;307917.
