Upgrading to SQL Server 2005

You can directly upgrade instances of SQL Server 2000 Service Pack 3 (SP3) or later, and instances of SQL Server 7.0 SP4 or later, to SQL Server 2005. You can perform most upgrade operations through Setup; however, some components support or require you to migrate applications or solutions after running Setup. For more information, see Upgrading SQL Server Components.

Before running Setup to upgrade to SQL Server 2005, you should first review system requirements and the upgrade matrix. To review system requirements, see Preparing to Install SQL Server 2005. To review the upgrade matrix, see Version and Edition Upgrades.

After reviewing system requirements and the upgrade matrix, run SQL Server Upgrade Advisor to analyze your instances of SQL Server 2000 and SQL Server 7.0. Upgrade Advisor produces lists of issues specific to your installations that you must fix before or after upgrading. SQL Server Setup will detect blocking issues that will prevent you from upgrading to SQL Server 2005, but will not list issues that may affect your applications.
