This topic explains how to remove the first Microsoft Exchange Server 2007 server from an organization that contains more than one Exchange 2007 server and one or more servers running Exchange Server 2003 or Exchange 2000 Server. When you install the first Exchange 2007 server in an existing Exchange 2003 or Exchange 2000 organization, the first Exchange 2007 server has the following distinguishing characteristics:

It contains the public folder database with free/busy information for Exchange 2003 or Exchange 2000 mailboxes. For more information, see Understanding Public Folders.
It is the source server for the first routing group connector between the Exchange 2007 routing group and the Exchange 2003 or Exchange 2000 bridgehead server. This routing group connector is created during installation of the first Exchange 2007 server. For more information about when Setup creates the first routing group connector, see How to Install Exchange 2007 in an Existing Exchange Server 2003 Organization.
It may be the source server for one or more Send connectors, through which outbound messages are sent. For more information, see Send Connectors.
It may be the source server for one or more Foreign connectors, through which messages to a non-Simple Mail Transfer Protocol (SMTP) messaging server are sent. For more information, see Foreign Connectors.

To remove the Exchange 2007 server that has these characteristics, you must perform this procedure so that these characteristics are preserved on another Exchange 2007 server in the organization.

Note:
If you move these characteristics to an Exchange 2007 server other than the first Exchange 2007 server that you installed, and then want to remove the other Exchange 2007 server, you must perform this procedure, even though that server is not the first Exchange 2007 server that you installed.

Before You Begin

To perform this procedure, the account you use must be delegated the following:

Exchange Organization Administrator role

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

To perform the following procedure, you must have more than one Exchange 2007 server in your organization.

Procedure

To remove the first Exchange 2007 server in a coexistence scenario

To move the contents of the first Exchange 2007 public folder database to a second Exchange 2007 server in your organization, perform the following steps:
1. If you do not already have a public folder database on the second Exchange 2007 server in your organization, create one. For more information, see How to Create a New Public Folder Database.
2. Move the contents of the first Exchange 2007 server public folder database to the public folder database on the second Exchange 2007 server. For more information, see How to Move Public Folder Content from one Public Folder Database to Another Public Folder Database.
3. Verify that all replicas have moved to the public folder database on the second Exchange 2007 server by using the Get-PublicFolderStatistics cmdlet. For more information, see Get-PublicFolderStatistics.

To modify the routing group connectors between the Exchange 2007 routing group and the Exchange 2003 or Exchange 2000 bridgehead server, run the following commands:

Get-RoutingGroupConnector | where {$_.SourceTransportServers -like "<First Exchange 2007 server>"} | Set-RoutingGroupConnector -SourceTransportServers "<Second Exchange 2007 server>"
Get-RoutingGroupConnector | where {$_.TargetTransportServers -like "<First Exchange 2007 server>"} | Set-RoutingGroupConnector -TargetTransportServers <Second Exchange 2007 server>

To modify any Send connectors that have the first Exchange 2007 server as the source transport server, run the following commands:

Get-SendConnector | where {$_.SourceTransportServers -like "<First Exchange 2007 server>"} | Set-SendConnector -SourceTransportServers "<Second Exchange 2007 server>"

To modify any Foreign connectors that have the first Exchange 2007 server as the source transport server, run the following commands:

Get-ForeignConnector | where {$_.SourceTransportServers -like "<First Exchange 2007 server>"} | Set-ForeignConnector -SourceTransportServers "<Second Exchange 2007 server>"

To verify that the connectors have been moved, test mail flow by using the Test-Mailflow cmdlet. For more information about the Test-Mailflow cmdlet, see Test-Mailflow.
Remove the Exchange 2007 server by using Add or Remove Programs from Control Panel. For more information, see How to Completely Remove Exchange 2007 from a Server.
To verify that there are no issues related to the server that you removed, in the Exchange Management Console of a remaining Exchange 2007 server, run the Microsoft Exchange Server Best Practices Analyzer Tool from the Toolbox.
