Question: can you transfer pokemon from pokemon moon to pokemon go?
Answer: Only the Pokémon you've caught in Pokémon GO that were originally discovered in the Kanto region (as well as their Alolan variants) may be transferred. You can't transfer Pokémon from Pokémon: Let's Go, Pikachu! or Pokémon: Let's Go, Eevee! to Pokémon GO, so be sure that you don't have any plans for them in Pokémon GO!
