Separate Solution: Creating a separate solution allows you to bundle the business process flow (BPF) along with any associated components, such as entities, fields, forms, views, etc., without including unrelated elements from the sandbox environment.
Export the Solution: After adding the BPF to the solution, you can export the solution. This process creates a solution package (.zip file) that contains the components you've included, making it easy to transport and import into another environment, such as the production environment.
No Data or Modifications: Exporting the solution without including unnecessary data ensures that only the design and configuration related to the business process flow are moved. This helps maintain the integrity of the production environment by avoiding unintended changes.
