Basically you need to remove routing group connectors between Exchange 2003-2007 but need to keep the Admin group as it is since legacyExchangeDN mapped with it... Refer below article step by step while removing last Exchange 2003 server.

You cannot indiscriminately delete routing group connectors. If a routing group connector serves as the only link between two routing groups or if it served as the only link between Exchange Server 2003 and Exchange Server 2007, and you delete it, then communications between routing groups will cease to function. You can either delete them from ESM or via EMS open the Exchange System Manager and navigate through the console tree toAdministrative Groups | your administrative group | Routing Groups | First Routing Group | Connectors, . Now, simply right-click on the routing group connector and choose the Delete command from the shortcut menu. You will have to repeat this process for any other routing group connectors that may still exist. You also have the option of using the Exchange Management Shell to get rid of any remaining routing group connectors. To do so, you would use the Remove-RoutingGroupConnector command. The syntax for this command is: Remove-RoutingGroupConnector Identity <routing group connector> [-confirm [<switch parameter>]] [-DomainController <domain controllers fully qualified domain name] Refrence:- click here Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|
