How to Upgrade the Repository Engine
SQL Server 2000 uses repository engine 3.0 . As a result, upgrading to repository engine 3.0 is accomplished when you upgrade an existing SQL Server or create a new SQL Server 2000 installation.
To take advantage of new repository engine features, we recommend that you upgrade the repository database to the latest format. Upgrading adds tables and columns that support new features. For more information, see Upgrading and Migrating a Repository Database.
