Best way to buy Deluxe Edition for Switch 2

Hey guys, im planning on buying the deluxe edition on switch 2. But it seems I would need to buy the switch 1 deluxe edition and then upgrade with the switch 2 upgrade pack?

Or would I also be able to buy the switch 2 base edition and buy the deluxe upgrade seperately? Its all a bit confusing to be honest.

Thanks in advance!
