Last week, we released an updated version of the Exchange Deployment Assistant (EDA). In case you haven’t heard of this tool, EDA is a Web-based deployment tool that asks you a few questions about your environment and then generates customized instructions for migrating to Exchange 2010. EDA was designed to make upgrading to Exchange 2010 or deploying a new Exchange 2010 organization as easy as following a checklist. Not only does the tool provide you with step-by-step instructions, but it also helps you verify that each step was completed successfully before moving on to the next step.
The version we released last week includes new cloud-based scenarios, such as cross-premises co-existence (where Exchange 2010 is deployed on-premises and in the cloud), and cloud-only deployments. The first co-existence scenario handles upgrading from Exchange 2003 to a cross-premises Exchange 2010 deployment. Cross-premises scenarios for Exchange 2007 and Exchange 2010 are coming soon. With coexistence, you get directory synchronization, single sign-on, Transport Layer Security (TLS) for transport, Free/Busy and calendar sharing, and more!
The cloud scenario involves migrating to Microsoft Office 365 for Enterprises. A cloud-only deployment is most often used when you want to migrate from your existing on-premises e-mail system to Exchange Online.
