Question: can you transfer pokemon from sword to shield on the same switch?
Answer: Yes, you can trade between family members with the Nintendo Switch version of Pokémon HOME. ... Please keep in mind that some Pokémon, once moved to Pokémon Sword or Pokémon Shield, can't be moved back to Pokémon: Let's Go, Pikachu! or Pokémon: Let's Go, Eevee! even if those games are where the Pokémon originated.
