What is the best method for migrating to Unified Messaging 2010 from 2007. Can I introduce an Exchange 2010 server into my Exchange 2007 cluster and use the Unified Messaging 2010 role? Will the UM enabled mailboxes need to be on a 2010 Exchange server before I can utilize the UM 2010 features? Any help would be greatly appreciated.
