System requirements for SharePoint Server 2010:

• SharePoint Server 2010 will be 64-bit only
• SharePoint Server 2010 will require 64-bit Windows Server 2008 or 64-bit Windows Server 2008 R2
• SharePoint Server 2010 will require 64-bit SQL Server 2008 or 64-bit SQL Server 2005.

So, what can you do today to get into the best shape for SharePoint Server 2010?

1. Deploying 64-bit is our current best practice recommendation for SharePoint 2007.
2. Deploy Service Pack 2 and check SharePoint 2010 Upgrade Checker that’s shipped as part of the update. The Upgrade Checker will scan your SharePoint Server 2007 deployment for many issues that could affect a future upgrade to SharePoint 2010.
