When Exchange 2013 Deployment Assistant was first released, as I wrote in a previous post it didn’t help organizations that are using On-Premises deployment and want to upgrade from previous versions of Exchange, because Exchange 2013 didn’t support it yet.
Now, after CU1 for Exchange Server 2013 was released, we can see these scenarios available:
“The Exchange Server 2013 Deployment Assistant is a web-based tool that helps you deploy Exchange 2013 in your on-premises organization, configure a hybrid deployment between your on-premises organization and Office 365, or migrate to Office 365”
