This section covers major product changes, classified in one of three categories: unsupported, discontinued, or affecting the way SQL Server 2000 or 2005 behaves today. Although the Upgrade Advisor tool will highlight these conditions if they are relevant to your environment, you should read this section to familiarize yourself with these changes.

English Query is no longer included; don't look for it on your installation media.
isql.exe and rbuildm.exe are no longer present. You will have to use sqlcmd.exe and setup.exe instead if you need to rebuild the master database or the registry.
The Northwind and Pubs databases have been replaced by the AdventureWorks2008 and AdventureWorksDW2008 databases. These new sample databases are intended to be more like real-life databases.

The metadata component of SQL Server 2000 DTS repository is deprecated as a feature. As part of the upgrade, the DTS packages will be migrated to the file system, and the specific tables will be present in msdb after upgrade.
