No
On Pokemon platinum, you cannot move or migrate Pokemon from Pokemon silver or Pokemon blue version. It can only be done from the Gameboy advanced games. Those are Pokemon Ruby, Sapphire, and Emerald version.
First, you need to migrate your Pokemon in Sapphire to Pokemon Diamond, Pearl, Platinum, HeartGold, or SoulSilver. Then, you need to migrate those Pokemon to Pokemon Black.
you need to migrate it from one of those original games
You need to have a GBA or GB game that is Pokemon and of Kanto or Hoenn, and put it in your DS. Then put platinum in too. Go the the main menu of Platinum and it will say something like "Migrate Pokemon from Pokemon ______" (whatever Pokemon version you have - Emerald, Red, etc.) And click on the link. And you have to migrate six Pokemon from that version to Platinum and have to use those Pokemon to be in a Catching Show. Hope this helped! :)
If you ONLY have Pokemon platinum/diamond/pearl, then you can't. If you have one of those AND a ruby/firered/leafgreen/Sapphire/emerald/and so on, then you can migrate.
with a copy of diamond, pearl, platinum, heartgold and soulsilver make sure you have 6 Pokemon in the PC in those games and head to the pokeshifter in Pokemon black and white and you can migrate those 6 Pokemon from the games listed above, see serrebii.net for more details.
Well, in Pokemon Platinum, all you have to do is see the Pokemon rather than capture it so if you're able to battle a trainer with that Pokemon, it will still count in your Pokedex. However, you can also make trades with people who do have those Pokemon or borrow a GBA game from a friend.
No, you can't, but you can migrate sceptile from ruby, sapphire emerald to pearl, diamond, platinum if you have one of those games.
As far as I know, Pokemon on Pokemon Black and White have to stay on those games, as for Pokemon HeartGold and SoulSilver, you can not only migrate Pokemon from earlier generations of games, you can also trade with Pokemon Platinum and Diamond and Pearl. Still, the Pokemon on Pokemon Black and White look cooler! :)
put the 2 games in the ds go on platernuim and press migrate instead of contiue but you have to have completed league and pkedex (not sure about pokedex) then get pal park!!
You either have to have Fire Red or Leaf Green in the GBA Slot. Or Migrate one from either of those Games. Or use and AR get one.
It's likely they won't be able to migrate into Diamond, Pearl or Platinum because you can just trade them into those games because all 5 of them are for the DS/DS Lite/DSi.
