EPiServer 4.6 and later fully supports SQL Server 2005, but is it possible to upgrade just the database for an EPiServer 4.50 site to SQL Server 2005? The ‘Microsoft SQL Server 2005 Upgrade Advisor’ reports that two stored procedures aren't compatible with SQL Server 2005. Will it be sufficient enough to keep the database's Compatibility Level at 80 (opposed to 90 for SQL Server 2005 mode)?
