Can I change the coordinate system of a camera path after the camera path has been created?
Remember that a coordinate system has two components: a position and a set of reference axes. You can’t change the positional component of a view path after the first keyframe has been added, but you can change the reference axes by going into the Keyframes page of the Camera Control Tool, selecting the view path, and pressing the Reference Axes button to select a new set of reference axes. In the future, it may be possible to change the positional component of a view path’s coordinate system as well.
