When Pokémon Sun and Moon was first announced, it was mentioned that the games will be compatible with Pokémon Bank. The announcement also stated that Pokémon from the Virtual Console versions of Pokémon Red, Blue, and Yellow would be transferable. However, it has now been announced that Pokémon Bank won’t work with the upcoming games until they get an update in January 2017. So, you will have to wait a few months before you can transfer your Pokémon into the new games.
