Transitioning from Exchange 2000 or 2003 to Exchange 2007 • Chapter 10 657 Moving Legacy Mailboxes to Exchange 2007 ˛ Moving legacy mailboxes to an Exchange 207 Mailbox server is a straightforward process and can be done using either the Move Mailbox Wizard in the EMC or the Move-Mailbox CMDlet in the EMS. ˛ If you will be running in a coexistence environment for a period of time, it’s important to understand that mailboxes stored on an Exchange 2007 server must not be managed using the Active Directory Users and Computers (ADUC) MMC snap-in but instead must be managed using the EMC or the EMS. However, Exchange 2003 mailboxes can still be managed using ADUC. ˛ If you want to move the mailboxes using the EMS, do so using the Move-Mailbox CMDlet. Using the Move-Mailbox CMDlet gives you a set of advanced options, among which the most interesting one is the option of specifying the number of mailboxes to be moved at a time (the Move Mailbox Wizard is limited to four). Redirecting Inbound Mail to the Exchange 2007 Server ˛ When all legacy mailboxes have been moved to an Exchange 2007 server, we can point SMTP traffi c (port 25/TCP) directly to the Exchange 2007 server so that inbound messages are routed directly to it. ˛ It’s recommended to deploy an Edge Transport server in your perimeter network (DMZ) and let this server route inbound messages to the Exchange 2007 server on your internal network. ˛ If you don’t want to deploy an Edge Transport server, you should bear in mind that you need to change the Permission Groups settings on the Default <server> receive connector under the Server Confi guration work center node | Hub Transport subnode in the EMC so that Anonymous users are allowed to connect to the Exchange 2007 server. Decommissioning the Exchange Legacy Server ˛ Exchange 2003 server should be removed using the Exchange 2003 Setup program. ˛ Before uninstalling the Exchange 2003 server, we fi rst need to assign the Recipient Update Service (RUS) to our Exchange 2007 server. ˛ Before uninstalling the Exchange 2003 server, we fi rst need to delete the routing group connector assigned to the Exchange 2003 Server. ˛ If the Exchange 2000 Setup fi les aren’t located on an accessible drive or network share, you will be prompted to insert the Exchange 2003 CD media during the uninstall process. ˛ If the Exchange 2003 uninstallation for some reason should fail, it might be necessary to remove the Exchange 2003 server by deleting the Server object in the Exchange System Manager, or if you’re unsuccessful doing this, too, then by using ADSI Edit. 658 Chapter 10 • Transitioning from Exchange 2000 or 2003 to Exchange 2007 Frequently Asked Questions Q: Can I do an in-place upgrade from Exchange Server 2000 or 2003 to Exchange 2007? A: No. An in-place upgrade from an Exchange 2000 or 2003 server to Exchange 2007 is not supported. To upgrade from any of these Exchange legacy servers to Exchange 2007, you must perform a transition, meaning that you’ll deploy Exchange 2007 into the existing Exchange organization and then move Exchange data and settings to Exchange 2007. Q: Can I do a transition from Exchange 5.5 to Exchange 2007? A: No. A transition from Exchange 5.5 or earlier versions is not supported. To move from Exchange 5.5 to Exchange 2007, you must fi rst upgrade to Exchange 2000 or 2003 and then move to Exchange 2007 from there. Q: In which order should I deploy Exchange 2003 Server roles when doing a transition from Exchange 2000 or 2003 to Exchange 2007? A: In a scenario where you will install the different Exchange 2007 Server roles on different hardware, you should fi rst deploy the CAS, then moved on and deploy the Edge Transport server in your DMZ. After you have deployed the Edge Transport server, you can deploy the Hub Transport server and then fi nally the Mailbox server. If you plan to use Unifi ed Messaging (UM) in your organization, you should deploy this server role after the Mailbox Server roles have been properly deployed. Q: How should I decommission any legacy Exchange servers (Exchange 2000 or 2003) when I’ve deployed Exchange 2007 in my Exchange organization? A: First, you should make sure that you have deleted any routing group connector assigned to the respective Exchange 2000 or 2003 server. Then you should assign RUS to the Exchange 2007 server (because an Exchange server responsible for RUS cannot be uninstalled). You can then open the Exchange 2000 or 2003 Setup program and remove each Exchange component in the Setup menu. Q: How do I establish a mail fl ow between the legacy Exchange servers and Exchange 2007 server in the organization? A: Because of the routing topology changes in Exchange 2007, you must set up a routing group connector between the legacy routing group and the Exchange 2007 routing group. You have the option of doing this during setup, but it can also be accomplished afterward using the New-RoutingGroup CMDlet in the EMS. Transitioning from Exchange 2000 or 2003 to Exchange 2007 • Chapter 10 659 Q: When I try to uninstall an Exchange 2000 or 2003 server using the Exchange Setup program, I receive an error message and cannot proceed. How should I remove the legacy Exchange server? A: If you have moved all mailboxes from the legacy Exchange server, deleted any routing group connectors associated with it as well as assigned RUS to another server. (If you only have one legacy Exchange server, you can assign it to an Exchange 2007 server because it isn’t used in Exchange 2007.) If you still receive an error message when trying to uninstall, you have two other options. You can either delete the respective server object using the Exchange System Manager, or if this isn’t possible, use ADSI Edit. Q: Will I lose all my global Exchange settings when I’ve fi nished the transition from Exchange 2000 or 2003 to Exchange 2007? A: No. Global Exchange settings such as recipient policies, Internet Message Formats, SMTP connectors, and Exchange delegation permissions will be transferred to the Exchange 2007 server automatically, since global Exchange settings are stored in Active Directory.
