Declan,
If you want to coexist you have to have a 2k3 server in the org.
Our tool does not need the connector to migrate but you will need it for coexistence I am afraid.

Coexistence between GroupWise and Exchange 2000/Exchange 2003 can be established by using both the Microsoft Exchange Connector for Novell GroupWise and the Microsoft Exchange Calendar Connector. Microsoft will not provide an Exchange 2007 connector for GroupWise. If you want to migrate from GroupWise to Exchange 2007 and to use the Microsoft connectors during a coexistence period, you need to have an Exchange 2003 server to talk to GroupWise. The catch is that you cannot install an Exchange 2003 server into an existing Exchange 2007 site!
The attached doc outlines the procedure.
At this stage I am not sure where our product sits - I will do some digging and find out if we can dispense with the 2k3 Exchange box.
