You can trade them from one game to the other, but you can't migrate them like you could from third gen games.
it is not possible to trade Pokemon with DS and GBA. you may if you have diamond, pearl, hg, ss, platinum you can MIGRATE Pokemon from GBA games to DS games. this can be done in the main menu under "Migrate From (name of your game)" example: Migrate From Firered or Leafgreen.
yes you can but you cant trade from pearl , diamond , platinum , soul silver , heart gold to Pokemon black & white
You have to trade it from Diamond, Pearl, or Platinum. You can't evolve Eevee into it in HG/SS.
