Flow activation and version management
Key Takeaway
A flow can have many versions, but only one version is active at a time, and the active version is the one that runs.
Flow activation and version tools let an admin choose which version of a flow runs, see how two versions differ, and go back to earlier saved work.
Activating a version
When you activate a version, the previously active version, if one exists, is automatically deactivated. Activation doesn't change work already in progress: any running flow interview continues with the version it started with.
For example, imagine a flow where version 1 is active, and you activate version 2. Version 1 is automatically deactivated, and version 2 is now the version that runs. A flow interview that started with version 1 before you activated version 2 continues with version 1.
