Boomi Flow includes a full versioning capability for flow edits. A new flow version gets created every time a flow is run or published.
You can access previous versions of your flow, by clicking the Properties icon on the right-hand-side navigation. Clicking on the edit button in the Properties dialog box, lets you activate a previous version of a flow.
When an older version of a flow is re-activated, the design time version of the flow doesn’t change.
The Flow Version ID stores the unique identifier generated by the Flow engine for each version of the flow. Every time you change the flow, a new version ID is generated. You can find the Flow Version ID at the bottom of your Flow canvas.
