First, this has nothing to do with branch lines, but with different deployment environments.
As long as you are not deploying to production, the easiest way is to copy databases to a new environment. If that is not an option, I encounter the following approaches in my projects:
- Certain modules come with export and import functionality,
- The AppStore may contact extensions to other AppStore modules, which allow for exporting and importing configuration, such as this example,
- Create XML export and import functionality yourself,
- Create a web service or REST API to retrieve the data in a new environment,
- Enter the information manually.
