3.2 apm firmware update-keep original settings

I now realize I need apm firmware update 3.2 for my 3drobotics quad to fly spline waypoints.
I am not clear whether the apm will keep my original parameter settings when I update to 3.2
I notice others are having some issues with 3.2 update, has it been determined these were “operator error” or
does 3.2 have issues

Thanks in advance: Tom Gates

If you go to the Full Parameter List screen in the MP you will find a “Load” and a “Save” button on the right side of the screen.
You can use the “Save” button to save your Full Parameter List to any location that you want to save it to and then recall it with the “Load” button.
The “Load” button only loads the full parameter list into MP, you must then “Write” the Full Parameter List to the navigation controller.
