We have recently upgraded to SQL Server 2008, some application still pointing to SQL Server 2005. I wrote this article just for FYI… HOW to restore SQL Server 2008 to SQL Server 2005. The same situation I face in my daily work. Backing up databases in SQL Server 2008 and then restoring them into SQL Server 2005 is not directly possible. The database backups are not backward compatible in SQL Server 2008.
