If you currently have the Beta 3 version of Microsoft® SQL Server™ on your computer, you can upgrade the installation to SQL Server version 7.0 rather than uninstall the Beta version and install a clean copy of SQL Server.
The benefit of upgrading from the Beta 3 version is that SQL Server retains the system and user databases, saving you the time involved in re-creating system settings and reloading data.
The benefit of uninstalling SQL Server Beta 3 and installing a clean copy of SQL Server is the time the Setup program takes to complete. Uninstalling and reinstalling is faster than running the scripts involved in the upgrade, but that time is lost if you have to re-create or reload system or user data.
If you proceed with the upgrade, SQL Server Setup prompts you for the sa password. You can select a typical, minimum, or custom installation. If you choose a custom installation, you can select which components to install. All other custom installation options are retained from the Beta 3 installation.
