|As a reminder, Microsoft Project Server 2003 Mainstream Support Retired on April 14, 2009, as show on our Microsoft Product Lifecycle site.
This means that Microsoft Project 2003 and Microsoft Project Server 2003 customers should purchase Extended Support.
I also recommend upgrading to Project/Project Server 2007 and not wait for Project/Project Server 2010.
See this for more information: Best Practices for Migrating to Project Server 2007 white paper now available
