You will need to be more explicit about what the actual issue is. Can you provide a minimal verifiable example or perhaps show the code that you wrote that isn't working? [Read How to Ask for more details.](https://stackoverflow.com/questions/how-to-ask) — MichaelD, Aug 12 '19 at 21:43

Open the repositories folder, open any of the repository file you have listed. You will see an import where the datasource is imported from, just change it to read from your new datasource.
