The SQL Server Upgrade Wizard is designed to be as problem-free as possible; however, there are situations that may interfere with upgrading Microsoft® SQL Server™ version 6.x databases to SQL Server 7.0. The most common upgrade error is the failure to create an object in SQL Server 7.0. In many cases, the problem is simple, such as running out of disk space. In any case, the SQL Server Upgrade Wizard creates detailed logs specifying the problem.
