I keep my old iPad as a back up. Apple has made it simple to make a clone of your old ipad. When firing up the new iPad chosse the copy from old iPad , it will then walk you thru a procedure using your new iPad’s camera to copy the moving circle on the old iPad. From there the devices take over and you just can sit back and wait for the copy to complete.
