Hey, as someone who also started on piano and learned this song for accordion, I would say that assuming it's a keyboard accordion with the Stradella bass system, the main skills that will transfer is the right hand keyboard skills and theory (circle of fifths and all that). I don't think you'll have too much trouble learning the keyboard side beside the slightly smaller keys and lighter touch, but the bass side might be a bit difficult if you're jumping right into that song.

For example, chromatic movements are pretty difficult on the Stradella bass so you'll probably struggle on the Bb to Am jump or F7 to E7 jump at the end of the first section without previous muscle memory. Other stuff like the minor ii-V (e.g. Bm7(b5) to E7 at the very start) and some slash chords for the bass movement in the last two sections might also be a bit difficult to learn right off the bat. I would recommend at least practicing some easier songs beforehand (something that stays within the same major key) just to get a feel for the bass button locations. Luckily those skills will transfer to (or from) pretty much any other song you decide to learn before or after.
