iPad from one image to another (Swapping iPads from one cart to another)

I have two iPad carts that I want to swap. One has newer iPads and one has older iPads. They are both current carts. Cart 3 and Cart 6. Both had prestage where they were assigned to their current cart. What is the easiest way to move the apps from Cart 3 iPads to the iPads on Cart 6 and vice versa.
If this is easy, please know I am a teacher who taught myself the jamf program and I am sure there is an easy way that I am just missing. Thank you for any help!!
