What you will need is:
Once you've beaten the main story on Pokemon White, go to Route 15. You'll find a building there that will give you the Poke Transfer option on the main menu. You will need to use the Download Play option on the other DS to send Pokemon over.
NOTE:
One method would be to transfer the Pokemon from your GBA game to your fourth generation game (Pearl, Diamond, Platinum, HeartGold, SoulSilver) through the pal-park feature and then proceed to transfer the Pokemon from your fourth-generation game to Pokemon White.
You need 2 DSs! after you beat Pokemon white go east of Nimbasa City past the bridge and there should be a building go in there. BUT MAKE SURE YOU HAVE 6 POKEMON IN THE PC IN POKEMON PLATINUM
