9. Decommission


Remove the Interop Routing Group Connector

When the Public Folder Database and the Mailbox Database are removed, and you’ve double checked to ensure that no other clients are using the Exchange 2003 Front-End server as an SMTP relay, the Interop Routing Group Connector can be removed. This can only be done using the Exchange Management Shell on an Exchange Server 2010 server by using the following command:
The Get-RoutingGroupConnector will return both Interop Routing Group Connectors (one from Exchange Server 2003 to Exchange Server 2010 and the other one vice versa) and this output will be used as input for the Remove-RoutingGroupConnector command.

Please make sure that absolutely no messages are remaining to be sent across the Interop Routing Group Connector before deletion!
                                                  Remove the Exchange Servers

Now that all services are not needed anymore on Exchange 2003 it’s time to remove the Exchange 2003 Front-End Server from our Exchange organization. Please use the Add/Remove Programs option in the server’s control panel to remove Exchange Server 2003. Please note that for uninstalling the Exchange 2003 Front-End Server you’ll need the installation media so keep this around.

The Recipient Update Service is the next to remove from the Exchange Server 2003 server. Open the Exchange System Manager and in the Recipients Container select the Recipients Update Service (domain). Right click this Recipient Update Service and select “Delete”. To remove the Enterprise Recipient Update Service it’s not possible to use the Exchange System Manager. To remove this you have to use ADSIEdit.

Open ADSIEdit and open the Configuration Container in Active Directory. Navigate to the

“CN=Recipient Update Services,CN=Address Lists Container,CN=Almora, CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=almora,DC=com”

Container. There you’ll find the Recipient Update Server (Enterprise) object. Right click this object and select “Delete”.

The Exchange 2003 Mailbox Server is the last Exchange 2003 server and is ready to be removed. As with the Front-End server please remove it using the Add/Remove Programs option in the server’s control panel.
