I haven't tested Express enough to know. There is an upgrade path from SQL 2000 to 2005, so I assume you will be able to upgrade MSDE to Express. You could look at http://lab.msdn.microsoft.com/express/sql/default.aspx to see if there is any info.

>Is there a big difference between MSDE and SQL Server Express? Can I easily replace MSDE with SQL Server Express once it's release version is available? Any comments or links related to this is welcome.
