lotus notes migration from 6.5 to exchange 2010

hI,everybody here,
   One of our customer is going to upgrade their mail system from Lotus domino 6.5 to 8.5 or Migrate it to Exchange 2010.  I can only find some documentation named "Microsoft Exchange Server 2003 Coexistence and Migration for Lotus Domino Mail" in technet. There is not any information about domino and exchange server 2010. Is this doc working well with exchenge server 2010? Or do we have any documentation or best practice steps in the migration of lotus domino mail to exchange 2010?


Thanks
