The built-in wizard to migrate DTS packages is approximately 40% successful and does not allow you to enjoy the benefits and best practices of SQL Server 2005 Integration Services (SSIS). DTS xChange is a product to help you migrate from SQL Server 2000 DTS to SQL Server 2005 or 2008 SSIS. It does this by applying a series of rules and best practices to your old DTS packages as it migrates the packages. The product was engineered to migrate thousands of packages with little intervention. DTS xChange is broken into three components: profiling, migration, and enterprise logging.
The program is now released and you can download a trial that will convert up to 10 packages (2 packages each time you open the program, up to 5 times) for free and profile all of your DTS packages.

This SQL Server 2005 task reads the properties of a file and writes the values to a series of variables. For example, you can use this task to determine if the file is in use (still be uploaded or written to) and then conditionally run the Data Flow task to load the file if it's not being used. You can also use it to determine when the file was created in order to determine if it must be archived.
