Looking to upgrade your infrastructure to Exchange 2010, then Microsoft has a tool to help make the process a little smoother. They’ve published an updated version of their Exchange 2010 Deployment Assistant, which now supports migration paths from Exchange 2007 as well as help with new 2010 installs. Previously, the assistant would only advise users of Exchange 2003.
The Deployment Assistant allows administrators to create Exchange 2010 deployment instructions that are customized to their environment. The Deployment Assistant asks a small set of questions, and based on your answers, it provides a set of instructions that are designed to get you up and running on Exchange 2010. Instead of reading dozens of topics in the Exchange 2010 library, you simply answer a few questions, and the Deployment Assistant gives you customized content to install Exchange 2010.
The assistant is strictly web based, and does not require you to run anything on your systems. It does require you to have intimate knowledge of your Exchange environment for the results to be very helpful. You can find it over at Technet.
