Change a workflow when you want to rebuild the project with a different starting structure.
Change the workflow
Open the project.
Click the current workflow icon or name in the project header.
Choose a different workflow.
Review the confirmation message, then continue if you want to apply the change.
What happens
Applying a different workflow clears generated sections so the new workflow can rebuild the project. The confirmation explains the effect before anything changes.
If you need to preserve the current version, duplicate the project before changing workflows.
