Move a relationship from upstream to downstream — or the other way — in one drag.
When a relationship is connected on the wrong side — upstream when it should be downstream, or vice versa — you don't delete and recreate it. You drag the element to the other connection point.
Step by step
Click the element you want to move. An orange border appears around both circles to show valid drop targets.
Drag the element to the other circle:
Right → Left to switch from downstream to upstream.
Left → Right to switch from upstream to downstream.
The relationship-type popup appears. Pick the relationship type for the new direction.
Click Done.
The relationship is now remapped. The change is staged until you commit.
