Upgrade from WSUS 2.0 to WSUS 3.0

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server 2008, Windows Server Update Services

The WSUS 3.0 installation program will upgrade all WSUS 2.0 settings to WSUS 3.0. Furthermore, if the installation program finds any SQL Server database other than SQL Server 2005 Service Pack 1 (or SQL Server 2005 Service Pack 2 for Windows Server 2008), it will back up the existing database, install Windows® Internal Database, and migrate the database to it. For more information on databases, seeChoose the Database Used for WSUS 3.0

You should make sure that your WSUS 2.0 installation is in good working order before upgrading.

  1. Check for recent errors in the event logs, problems with synchronization between downstream servers and upstream servers, or problems with clients not reporting. Make sure that these issues have been resolved before continuing.

  2. You may want to run DBCC CHECKDB to ensure that the WSUS database is correctly indexed. For more information about CHECKDB, see DBCC CHECKDB (http://go.microsoft.com/fwlink/?LinkId=86948).

  3. Back up the WSUS database.

If you have installed WSUS 2.0 on one computer and the SQL Server database on another, you must uninstall WSUS 2.0 from the database server before upgrading to WSUS 3.0.

noteNote
Please make sure that your WSUS 2.0 database is not corrupt before upgrading.

  1. Uninstall WSUS 2.0 from the back-end computer. Do not choose to delete the database.

  2. Install WSUS 3.0 on the front-end computer.

The Windows Server Update Services 3.0 Operations Guide (http://go.microsoft.com/fwlink/?LinkId=81072) includes other types of migration documentation, such as migrating from Windows Internal Database to Microsoft SQL Server.

It is a good idea to reindex the database after you upgrade. For more information about reindexing the database, see Appendix I: Database Maintenance in the WSUS 3.0 Operations Guide.
