Microsoft Exchange Server 2010 can be deployed in an Active Directory directory service forest that has an existing messaging system. You have a coexistence scenario if the following conditions are true:

• Exchange 2010 is deployed in an existing Exchange organization.
• More than one Exchange version provides messaging services to the organization.

When a large organization gradually transitions a messaging system from Exchange Server 2003 or Exchange 2007 to Exchange 2010, the organization will probably have to maintain more than one version of Exchange during that time. This topic provides an overview of the coexistence scenarios that are supported for Exchange 2010 and an overview of the configuration steps that you must perform to maintain coexistence.

Supported Coexistence Scenarios

Le tableau suivant répertorie les scénarios pour lesquels la coexistence entre Exchange 2010 et les versions précédentes de Exchange est prise en charge.

Deploying Exchange 2010 Server Roles to Coexist with Exchange 2003 and Exchange 2007

You can only deploy Exchange 2010 in an Exchange 2003 or Exchange 2007 organization that operates in native mode. The following steps show you how to use Exchange System Manager to change the Exchange organization to native mode on an Exchange 2003 server

1. Start Exchange System Manager. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Right-click the organization and then click Properties.
3. Click the General tab, and then, under Change Operations Mode, click Change Mode. Click Yes if you are sure that you want to permanently switch the organization's mode to native mode.
