The approach mentioned by Connections Academy Developer is correct, however the same can be achieved without adding the service file, Telerik.Sitefinity.MigrationContracts.dll and the modification to web.config if you are using the automatic migration from Sitefinity 4.4 project manager because it adds all necessary files and modifies the web.config autmatically.
