Notes to Exchange Migration

Hi Guys,,

just wondering if anyone can shed some light on whats required to migrate exsting EX archives from Notes to Exchange. the notes to exchange migration has been done, there is a new EX server running that is configured for the exchange enviroment, and the existing EX server is still in place. Is it just a matter of importing the existing archives? is there anything special required for this?
or is there another way to do this?

thanks
