Can I transfer Animal Crossing save to a new Switch?

[SecondWar]

As far as I know, no. And that goes for all Switch games, not just Animal Crossing. I looked into this when I realised that my Pokemon Sword file was saved on my Switch rather than the game cartridge as with past Nintendo handhelds. There isn’t even a harddrive slot to swap out, which is a problem given the Switch’s rather limited save space.
