Journey Optimizer allows you to copy an entire journey from one sandbox to another. For example, you can copy a journey from your Stage sandbox environment to your Production sandbox.
In addition to the journey itself, Journey Optimizer also copies most of the objects the journey depends on: audiences, schemas, events and actions.
The copy process is carried via a package export and import between the source and target sandboxes. Detailed information on how to export objects and import them into a target sandbox are available in this section: Copy objects to another sandbox
