The Microsoft Exchange Server 2007 deployment phase is the phase during which you install Exchange 2007 into your production environment. Before you begin the deployment phase, you should plan your Microsoft Exchange organization. For information about planning your Exchange 2007 organization, see Planning and Architecture.

The deployment topics are grouped into the following categories:

Each of these categories is described in the following sections.

Preparing to Deploy Exchange 2007

Before you install Exchange 2007, make sure that you prepare your system. The topics in this section include system requirements for Exchange 2007, a security checklist to help you verify the security of your system, information about Exchange 2007 Administrator roles, and information about configuring Domain Name System (DNS) settings for Exchange 2007. For more information, see Preparing to Deploy Exchange 2007.

New Installation

The New Installation topic discusses the scenario in which you install Exchange 2007 into a new Exchange organization. This section includes the following topics:

  • Deploying Server Roles   This topic includes procedures for installing Exchange 2007 by using the Exchange Server 2007 Setup wizard or commands from a command prompt.

  • Connecting Forest Topologies   This topic includes procedures for installing Exchange 2007 in new multiple forest topologies.

Upgrading to Exchange 2007

The Upgrading to Exchange 2007 topic includes the scenarios in which you either transition or migrate to Exchange 2007 from a previous version of Exchange or from another non-Exchange messaging system, or coexist with different versions of Exchange as a single Exchange organization.


Transition is the scenario in which you upgrade an existing Exchange organization to Exchange 2007.

You cannot perform an in-place upgrade of an existing server running Exchange Server 2003 or Exchange 2000 Server to Exchange 2007. Instead, you must install a new Exchange 2007 server into the existing organization, and then move data to the new Exchange 2007 server. Because a transition includes the installation of one or more new Exchange 2007 servers, some procedures will be the same as for new installations. For detailed steps about how to transition to Exchange 2007, see the following topics:

Coexisting with Exchange Server 2003 and Exchange 2000 Server

Interoperability is the ability of a program or system to share data and resources or to communicate with different programs and systems. Exchange 2007 can interoperate with non-Exchange messaging systems. In some cases, Exchange shares directory information and mailbox information with the other programs and systems. For example, with Exchange 2003 and the Lotus Interoperability and Migration Tools connectors, you can send calendar information and free/busy data between Lotus Notes and Exchange.

Coexistence is the scenario in which multiple versions of Exchange are deployed as a single Exchange organization. These multiple versions of Exchange can communicate with each other and share data resources, recipient information, and configuration information. For example, computers running Exchange 2007 can coexist with computers running Exchange 2003 or Exchange 2000.

For more information, see Coexisting with Exchange Server 2003 and Exchange 2000 Server.


Migration is the scenario in which you upgrade to Exchange 2007 by migrating data from a non-Exchange messaging system to Exchange 2007 or from an existing Exchange organization to a completely new Exchange organization, without retaining any of the Exchange configuration data in the first organization. Because migration includes the installation of one or more new Exchange 2007 servers, some procedures will be the same as for new installations. For detailed steps about how to migrate to Exchange 2007 from Lotus Notes, see Migrating from Lotus Notes.

Post-Installation Tasks

After you install Exchange 2007, you must configure your Exchange servers. Some post-installation tasks are required to complete the deployment of your Exchange 2007 organization. These tasks apply to features that are enabled by default but require additional configuration. Other post-installation tasks are optional and are for configuring additional features. For more information, see Post-Installation Tasks.

Removing and Modifying Exchange 2007

In some situations, you may want to remove Exchange 2007 from a server or from your entire organization. You may also want to remove only one Exchange 2007 server role from a physical server or add an additional server role to a server. For more information about removing and modifying Exchange 2007 in each of these scenarios, see Removing and Modifying Exchange 2007.

Recommended Deployments

The topics in this section describe the end-to-end deployment scenarios for some example topologies. For more information, see Recommended Deployments.
