Installing Exchange Server 2007
Before you install Exchange 2007 in your new or existing organization, make sure that your organization and servers meet Exchange 2007 requirements. For more information, see the Exchange 2007 System Requirements.
Upgrading to Exchange Server 2007
You cannot upgrade an existing Exchange Server version 5.5 organization to Exchange 2007. You must first migrate from the Exchange Server 5.5 organization to either an Exchange 2003 organization or an Exchange 2000 organization, and then you can transition the Exchange 2003 or Exchange 2000 organization to Exchange 2007.
