Has anyone tried it yet? Can ALL the Pokemon I collected, would go to home and all to sword and shield?
Pokemon Home support every Pokemon, but SwSh do not. SwSh only supports the 400 Pokemon in the Galar Pokedex (including non-Galarian forms), the 211 Pokemon in the Isle of Armor Pokedex (including non-Galarian forms), and 35 others.
As long as the Pokemon is programmed into the game, then you will be able to move it from Home into the game. Additionally, this list will expand when the Crown Tundra releases.
