Removing Exchange Bridgehead Server for Routing Group from Exchange 2007

I recently migrated a server from Exchange 2007 to Exchange 2013.  They co-exist for now but I wish to uninstall the 2007 Server.  Running the uninstallation from Add/Remove programs I am getting the following error while attempting to remote the Hub Transport Role:

Error: This computer is configured as a bridgehead server for 1 routing group connector in the organization.  These must be moved or deleted before Setup can continue.

The problem is that I cannot locate this bridgehead in either the 2007 console or 2013 management page.  I suspect that it could be a legacy bridgehead from a previous migration years ago from 2003 to 2007.  

I found a command that is supposed to remove the bridgehead:

Remove-RoutingGroupConnector -Identity"[[Administrative Group Name\]Routing Group Name]\Routing Group Connector Name"

I don't, however, know how to populate the Administrative Group Name, Routing Group Name and Routing Group Connector Name properly.

Is there a shell command or a place in the registry (or ADSI Edit) that will give me those properties?

If this can't be removed easily through Powershell, can someone offer advice as to how to proceed with the decommissioning of the 2007 server?

Run this first:

get-routinggroupconnector

If it comes back with any results, then you still have the RGC from the Exchange 2003 migration in place.

To remove it, simply run

get-routinggroupconnector | remove-routinggroupconnector

It will do the rest.
