Exchange Team has released the deployment assistant for 2013 to help admins get through the tasks required in deploying a 2013 platform.
The Deployment Assistant is a web-based tool that helps you deploy Exchange 2013 in on-premises organization, configure a hybrid deployment between on-premises organization and Office 365 or migrate to Office 365. It asks a small set of simple questions and then, based on the answers, creates a customized checklist with instructions to deploy and configure Exchange 2013. Instead of trying to find what you need in the Exchange library, the Deployment Assistant gives you exactly the right information you need to complete your task.
The first scenario available shows how to deploy Exchange 2013 in an organization with no previous installations of Exchange. Other upgrade scenarios are still in development.
