Migrate is when you begin to add new features and enhancements in OpenEdge to your application without changing your application?s architecture.
The migrate process take place after you have successfully upgraded to OpenEdge 10. You can then select the new features to be built into your application and include them in your normal development release schedule. New features can be deployed in parallel with your existing application.
