Today the MS Exchange Team released the ExPDA tool, or Exchange Server Pre-Deployment Analyzer. This tool is meant to scan and analyse your current e-mail enviroment for possible. ExPDA can also be used as an decisionmaking tool, helping you through the process of implementing Exchange 2010.

ExPDA is based on ExBPA – Exchange Best Practice Analyzer – but looks more at the complete topology than at the system level. Amongst many other things, it scans current Exchange (2003, 2007) systems and domain controllers/gc’s for required patchlevels, connectors and domains and forests for required modes in order to implement Exchange Server 2010.

ExPDA runs on Windows 7, Vista SP2, Windows Server 2008 SP2, Windows Server 2008 R2 and even Windows Server 2003 SP2. Check the team’s announcement for more details. You can download ExPDA here.
