How to transfer your original Switch data to a Switch 2

So, you got (or are soon getting) a Nintendo Switch 2. You're probably ready to throw your original Switch into storage, but before that, you should transfer all of your data to the new console.

Good news: it's easy for those who have a Switch 2. Not only that, it's easy even if you don't yet have the new console. Nintendo developed a clever solution for those who haven't upgrade yet, letting original Switch owners back up their entire account to a remote server, where it will be stored for one year.
