Basically it's the same procedure as when transporting from dev > qa > prod. I recommend to export from prod to dev, and from there it's business as usual 
Design objects can easily be exported to file system from production and imported in development.
File export can also be used for configuration objects, but in order to import business systems in the development system, you have to maintain a corresponding transport target in SLD for the production business system to map it to the appropriate development business system.
Then of course, you need to configure the adapters for your dev and qa landscape.
