Quick reminder that the recently released Public Beta of Project Server 2010 will NOT be upgradable to the final release (RTM) of Project Server 2010 due out next year. This also applies to SharePoint Server 2010.
Hence the Project Server 2010 Public Beta should be used for evaluation and feedback purposes only (any data entered in a Public Beta PWA instance will have to be re-entered at RTM).

This expectation has been documented on the Public Beta download page, TechNet and on MSFT blogs (2010 Public Beta to 2010 Final Release Is Not Supported).

The only exception to this is Project 2010 TAP and RDP customers. The TAP and RDP programs are now closed to new entrants.
