If you use PowerPoint Viewer or an earlier version of PowerPoint, all the features of the slides might not be displayed correctly. Preparation tasks To prepare for this module: Read all of the materials for this module. Work through the Module Review and Takeaways section, and determine how you will use this section to reinforce student learning and promote knowledge transfer to on-the-job performance.
  • Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • This topic is intended to be an overview slide for lesson one. The second lesson describes how to perform a upgrade from Microsoft Exchange Server 2003 with Service Pack 2 (SP2) to Exchange Server 2010, and the third lesson focuses on how to perform a upgrade from Microsoft Exchange Server 2007 with Service Pack 2 (SP2) . Discuss the differences between a upgrade and a migration. In a upgrade, you install Exchange Server 2010 into an existing Exchange Server 2003 or Exchange Server 2007 organization. In a migration, you install Exchange Server 2010 into a new organization, and then migrate mailboxes and other objects from the current messaging system to Exchange Server 2010. Upgrades are usually easier to perform than migrations, but upgrades are limited to only Exchange Server 2003 or Exchange Server 2007 organizations. Mention that because this module covers the upgrading scenarios, it does not include a lab. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Highlight the Active Directory ® Domain Services (AD DS) and Active Directory directory services requirements for performing a upgrade. All global catalog servers must be running the Windows Server ® 2003 SP2 or newer operating system, and the domain and forest functional levels must be running the Windows Server 2003 operating system or higher. Also stress that Service Pack 2 or newer is required for both Exchange Server 2003 and Exchange Server 2007 upgrades. Exchange Server 2010 setup will fail if the computers are not upgraded to SP2. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • As part of the overview for this module, this topic describes some of the upgrade strategies. Stress that in all but the smallest organizations, a single phase upgrade is not feasible. This means that in most upgrades, there is a short or extended period of coexistence between the Exchange Server versions. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Tell students that Microsoft provides several tools, free of charge, to help them deploy Exchange Server 2010. Briefly discuss these tools, and if time permits , demonstrate all or some of them. We recommend that you show students the new Exchange Deployment Assistant because that tool was not available earlier . ( An Internet connection is required .) Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Mention that in order for Exchange Server 2010 to coexist with Exchange Server 2003, the Active Directory permissions assigned to Exchange servers must be modified. Running Exchange Server 2010 Setup with the /PrepareLegacyExchangePermissions command makes this change. Mention that students do not have to run Setup with the /PrepareLegacyExchangePermissions parameter if they run Setup with the /PrepareAD parameter. If /PrepareLegacyExchangePermissions has not been run, /PrepareAD applies the same changes. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Stress that Client Access servers must be deployed first and that all client connections must be configured to connect to the Client Access server. Mention that although Exchange Server 2003 does not use Active Directory sites for message routing, Exchange Server 2010 has a dependency on Active Directory sites for options such as message routing and client access. This means that you have to consider Active Directory sites during the upgrade. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Use the diagram describe the different scenarios that occur when the different messaging clients connect to the Exchange environment during coexistence. Emphasize the process used by Outlook® Web Access, pointing out the requirement for two different URLs so that the client request can be referred to the Exchange Server 2003 front-end server if the mailbox is located on an Exchange 2003 server. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • For clients other than Outlook to connect to the user mailboxes and use the single sign-on feature, the clients must be configured to use the Exchange Server 2010 Client Access server as the first point of connection. The Client Access server may then redirect the client to an Exchange Server 2003 front-end server, or it may proxy the client request to an Exchange Server 2003 front-end server. Because you can redirect client requests from the Exchange Server 2010 Client Access server to an Exchange Server 2003 server, you will need to enable Internet access for multiple URLs. Stress the importance of using server certificates that support all of the URLs. Because all clients are connecting to an Exchange Server 2010 Client Access server when the user mailboxes are moved to Exchange Server 2010, you must plan for Client Access server capacity. In previous versions of Exchange Server, the recommended deployment ratio was one Client Access server processor core for every four Mailbox server processor cores. In Exchange Server 2010, the recommended ratio is 3 to 4. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Consider discussing the differences between how Exchange Server 2003 and Office Outlook versions prior to Outlook 2007 access free/busy information and the offline address book. Because the Exchange Server and client version architectures differ significantly, you must retain both the Exchange Server 2003 and the Exchange Server 2010 options for accessing this information. Also mention that you can replicate public folders from Exchange Server 2003 servers to Exchange Server 2010 servers. As Exchange Server 2003 servers are removed from the organization, the Exchange Server 2010 servers can host all the public folders. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Use a whiteboard diagram to show how a routing group connector is created when the first Exchange Server 2010 Hub Transport server is deployed in an Exchange Server 2003 organization. Consider extending the diagram to describe what happens as Hub Transport servers replace bridgehead servers across multiple Active Directory sites and routing groups. Because Exchange Server 2010 uses Active Directory sites rather than routing groups to manage routing, replacing bridgehead servers can change the routing topology significantly. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Use the table to describe the options for configuring administrative permissions in Exchange Server 2003, and how those same permissions can be assigned in Exchange Server 2010. Stress that because using role-based access control (RBAC) to assign permissions is so flexible, you can duplicate any Exchange Server 2003 administrative permission configuration. Ask students if Exchange Server 2003 limited their ability to assign permissions. For example, did their organization have requirements for delegating administrative permissions that were not possible in Exchange Server 2003? Discuss whether the same limitations will apply in Exchange Server 2010. Stress the importance of managing each Exchange Server version with the correct version of management tools. Once Exchange Server 2010 is introduced into the organization, all organization-level settings should be configured using the Exchange Server 2010 tools, but all server-level administration settings should be performed using the management tools that come with each version. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Discuss additional tasks that you should perform before removing old Exchange Server from organization. Tell students that they can use EMS to perform object upgrade procedures. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Stress the importance of removing the mailbox servers in the correct order when upgrading from Exchange Server 2003. Because of the changes to the Client Access architecture in Exchange Server 2010, an Exchange Server 2003 server that supports non-MAPI client connections must be retained until the last mailbox has been moved to an Exchange Server 2010 server. Review some of the functionality that was available in Exchange Server 2003 that is not available in Exchange Server 2010. Examples include the Novell GroupWise connector and the Inter-Organization Replication tool. Mention that some organizations may need to retain one or more Exchange Server 2003 servers to retain this functionality. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Mention that the Exchange Server 2010 setup program checks the status of the current Exchange Server deployment. If SP2 is not installed on the Exchange 2007 servers, the installation will not complete. Emphasize that Exchange Server 2010 SP2 includes several schema updates. This means that the Service Pack deployment may be more complicated than most because of the requirement for testing schema updates in most organizations. Stress that Client Access servers must be deployed first and that all client connections must be configured to connect to the Client Access server. For most client connections, the Exchange Server 2010 Client Access Server will proxy the client request to the Exchange Server 2007 Client Access server. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Use the diagram to describe the different scenarios that occur when the different messaging clients connect to the Exchange environment during coexistence. Emphasize the following differences from how the client access works with Exchange Server 2003: Microsoft Exchange ActiveSync® clients can connect to either the Exchange 2010 Client Access server or the Exchange 2007 Client Access server The Client Access servers can proxy Exchange ActiveSync and Web Services requests between versions. The Exchange 2010 Client Access server can proxy client requests to Exchange 2007 Client Access servers in sites that are not accessible from the Internet. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Stress that because Exchange Server 2007 Mailbox servers require Exchange Server 2007 Client Access servers, the last Client Access servers cannot be removed until all of the mailboxes have been moved to Exchange Server 2010 Mailbox servers. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Emphasize that Exchange Server 2007 Mailbox servers require Exchange Server 2007 Hub Transport servers in addition to Exchange Server 2007 Client Access servers. However, once all the mailboxes are moved to Exchange Server 2010 servers, you can remove the Exchange Server 2007 Hub Transport servers. You can do this on a per-site basis. For example, after moving all of the mailboxes to Exchange Server 2010, you can remove the Exchange Server 2007 Hub Transport server. The Exchange Server 2010 Hub Transport server in one site can send and receive emails with Exchange Server 2007 Hub Transport servers in the same or other sites. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Review the list in the student manual of tasks that can be performed in each version of Exchange Management Console. Point out that the Exchange Management Console enforce the rules about what tasks can be performed on each version of Exchange server so there is no danger in inadvertently modifying a setting using the wrong version of Exchange Management Console. As you discuss the options for replicating the delegation of Administrative permissions in Exchange 2010, ask students how they have configured permissions in Exchange 2007 (if they are running Exchange 2007). You can then describe how they can replicate the permissions in Exchange 2010 using role groups. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Stress the importance of removing the servers in the correct order when upgrading from Exchange Server 2007. Mention that once you have removed the last mailbox from the Exchange Server 2007 mailbox servers and moved all connectors to Exchange Server 2010, you can remove all other Exchange Server 2007 server roles because they are no longer used. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Review Questions Your organization is deploying Exchange Server 2010 in an Exchange 2003 organization. You have made the changes to Active Directory. What is the first Exchange 2010 server role that you should deploy? How will this deployment change the user experience? Answer: You should deploy the Client Access server role first. However, this deployment will not change the user experience until you configure the non-MAPI clients to use the Client Access server for a mailbox access. Why do you need to configure a new external URL on Exchange Server 2007 Client Access servers when you deploy Exchange Server 2010 Client Access servers? Answer: The external URL redirects Outlook Web Access requests for users whose mailboxes are on Exchange 2007 Mailbox servers. The Autodiscover service on the Exchange 2010 Client Access server uses this URL to redirect the clients. Your organization includes two locations and Active Directory sites. You have deployed Exchange Server 2007 servers in both sites. You now are deploying Exchange Server 2010 servers in one of the sites and removing the Exchange Server 2007 servers. When can you remove the last Exchange 2007 Hub Transport server in the site? Answer: You can remove the last Hub Transport server when you move all of the mailboxes, public folders, and connectors from the Exchange Server 2007 servers in the site. As long as there is an Exchange 2007 Mailbox server in the site, you must maintain an Exchange 2007 Hub Transport server. Common Issues Related to Upgrading to Exchange 2010 Issue: When you try to remove an Exchange Server 2003 server, you receive an error message that you cannot remove the server because it is a bridgehead server for a routing-group connector. You have upgraded all external message routing to Exchange Server 2010. Troubleshooting tip: The Exchange Server 2003 server may be the designated routing-group bridgehead server for the routing-group connector between the Exchange Server 2003 routing group and the Exchange Server 2010 routing group. If this is the last Exchange Server 2003 server, you can remove it from the routing-group connector. If you have other Exchange Server 2003 servers deployed, you will need to designate one of them as the routing-group connector’s bridgehead server. Issue: You are upgrading your Exchange Server 2007 organization to Exchange Server 2010, and you have configured Client Access servers for Internet access. Users with mailboxes on Exchange Server 2010 Mailbox servers can access their mailbox using Outlook Web App from the Internet, but users with mailboxes on the Exchange Server 2007 Mailbox servers cannot. Module 12: Upgrading from Exchange Server 2003 or Exchange Server 2007 to Exchange Server 2010 Course 10135B
  • Troubleshooting tip: Check the DNS configuration to ensure that users from the Internet can resolve the host name for the alternate or legacy URL that you have configured. Also, check the reverse proxy or firewall configuration to ensure that all client requests to the legacy URL are directed to the Exchange Server 2007 Client Access server. Issue: You have deployed Exchange Server 2010 servers in your Exchange Server 2007 organization. You need to modify the settings on both Exchange Server 2007 and Exchange Server 2010 servers, but you cannot see both servers in the Exchange Management Console. Troubleshooting tip: You have to use the same version of the Exchange Management Console as the server that you are managing. Real-World Issues and Scenarios A. Datum has three office locations and three Active Directory sites. They have deployed Exchange Server 2003 servers in all offices, but have enabled Internet access to the servers only in the main office. What high-level process should A. Datum use to upgrade to Exchange Server 2010? Answer: They should upgrade the main office first, as this is the only site that is accessible from the Internet. After the upgrade in the main office is complete, they can upgrade the other offices. Your organization has deployed Microsoft Forefront® Threat Management Gateway (TMG) to secure access to the Client Access server deployment. You have completed all of the steps required to enable access to both the Exchange 2010 Client Access server and the Exchange 2007 Client Access server. What changes do you need to make on the TMG server? Answer: You need to configure TMG to forward all requests using the main Client Access server URL to the Exchange Server 2010 Client Access server. Then you need to configure Forefront TMG to forward requests sent to the alternate or legacy URL to the Exchange Server 2007 Client Access server. Your organization is deploying Exchange Server 2010 in an Exchange Server 2003 organization. Your organization does not provide Internet access to messaging clients, and all users are located in a single office. You deploy an Exchange Server 2010 server using a standard installation. What else do you need to do before you start moving mailboxes to the Exchange Server 2010 server? Users need to be able to access their mailboxes by using Outlook Web App and Outlook 2003. Answer: You do not need to do anything else before you start moving mailboxes. During the installation of the Hub Transport server role, you will be prompted for the Exchange Server 2003 server’s name that will be the routing group bridgehead server, to enable message flow. However, with this configuration, Exchange Server 2003 users need to use an Exchange Server 2003 front-end server to access their mailbox through Outlook Web Access, and they need to switch to the Exchange Server 2010 Client Access server when their mailbox moves. To enable the users to use the Exchange 2010 Client Access server while their mailbox is on the Exchange Server 2003 server, you need to add the Exchange 2003 URL to the Exchange 2010 Client Access server. Best Practices for Supporting Users Running Applications on Windows XP Help the students understand the best practices presented in this section. Ask students to consider these best practices in the context of their own business situations.
