No, items can't be migrated, but if you migrate Shaymin across, take it to Lacunosa Town's Pokemon centre, a woman inside will give you the Gracidea.
You can obtain the gracidea flower in one condition. You have to transfer the Shaymin from the Nintendo Event or from Oak's Letter via Mystery Gift in Pokemon Platinum. So first have the Shaymin in either Platinum, HG or SS and transfer it to your White game. PS. You needed 2 DS to transfer.
Yes. After you beat the main story, you can migrate from daimond, pearl, platinum, heartgold, and soulsilver versions to black and white
Not directly. You have to migrate to diamond pearl platinum heartgold or soulsilver first and then after you beat the elite 4 in white you can connect 2 da systems to migrate from diamond pearl platinum heartgold or soulsilver over to Pokemon black or white.
You cannot catch a Shaymin in Pokemon White. However, if you migrate a Shaymin from a Gen IV game, you can get the Gracidea flower to make it sky forme. Go to Lacunosa City (east of Opelucid City after you beat the game) and there will be a girl in the Pokemon center who talks about the Gracidea flower. Talk to her with Shaymin as the first Pokemon in your party and she will give you the Gracidea. (it may not work if you have a hacked, non-event shaymin.
You must migrate it from Diamond/Pearl/Platinum/Heartgold/Soulsilver.
You can migrate it from a copy of Diamond, Pearl, Platinum, HeartGold or SoulSilver.
You can't; you need to migrate one over from Diamond, Pearl, Platinum, HeartGold or SoulSilver.
