How trade between sapphire and platinum?

Question

My friend has sapphire so I wanted to trade him a metagross that doesn't know sinnoh moves but I do not know how.

Answer 1

Impossible - you can migrate Pokémon from III gen to IV gen, but not trade or migrate Pokémon back

Comments

I think you mean gen III not gen II. You can't migrate from second gen.
