I am assuming that you want to migrate from a GBA game to Pokemon Diamond, Pearl, or Platinum. These are the only games that Pokemon can be migrated to. Now, follow these easy steps:
you can't i tried
mirgrate or trade from anothher version
No , you cant ...But you can just trade them , by using another DS
you can get it from fire red in cerulean cave in mirgrate it to diamond
You need to mirgrate it. Unless you cheat.http://www.youtube.com will prove it.
no but you can trade between platinum and pearl/diamond if you have 2 Nintendo ds's.
1. start a new game then trade it from that game 2. Mirgrate a Pokemon holding it
Yes jellyfish do migrate
War, famine, no work, bored
yes snake bird will mirgate
Sheep neither hibernate nor mirgrate.
You just migrate them, its ur choice if u want to start a new game and delete your old one. Or you could get Pokesav and buy an AR and make ur own cheat to replicate ur Pokemon from ur fire red so you don't hvae to migrate them. But that takes a lot of time ( maybe an hour or two )
