To ensure uninterrupted operation of your SQL Server 2000 Data Transformation Services packages, make sure that Legacy Components is selected when you install SQL Server 2008 R2.

Legacy Components are also required to support the DTS Package Migration Wizard, a tool you can use to create new SQL Server 2008 R2 Integration Services packages based on your existing SQL Server 2000 packages. The package migration process is not completely automatic. Use the options in the dialog box to analyze your existing SQL Server 2000 DTS packages for potential migration issues.
