First you have to beat the Elite 4 on each game. Then you insert your 2 games into your DS. Then when you get to the title screen on Pokemon pearl there will be a box that says migrate. But before all that you have to have six Pokemon that are not legendary. Different Person That's not quite right. You can't migrate Pokemon from D/P because the makers of Firered hadn't thought that they would be making the D/P versions yet, though R/S versions were already underway.
That would be FireRed/LeafGreen/Ruby/Sapphire/Emerald.
No
Special: Migrate from FireRed or LeafGreen. (Unobtainable in Diamond and Pearl.)
To catch Mewtwo in LeafGreen or FireRed no. To migrate Mewtwo from LeafGreen or FireRed to Diamond/Pearl/Platinum yes you have to have it in Diamond/Pearl/Platinum.
If you're talking about FireRed and LeafGreen versions, Scyther can be found in the Safari Zone in Fuschia City. It is only available in FireRed.
Leafgreen and Firered, Pearl and Diamond
I think you can only pass Pokemon from Emerald to Diamond/Pearl
That would be FireRed/LeafGreen/Ruby/Sapphire/Emerald.
No
You can`t get tangela in Pokemon diamond version. You have to migrate it from Pokemon firered or Pokemon leafgreen versions or if you bye platinum version you can get tangela in the great marsh.

You must migrate Venasaur from FireRed/LeafGreen to Diamond.
First, you have to trade your Pokemon Colosseum with Ruby/Sapphire (And I think Leafgreen/Firered too) Once you do that, you have to get the Pokemon to leafgreen/firered, and then migrate them to Pokemon diamond/pearl. For this though, you have to had beaten the games.
You cannot see it in the wild in Pokemon Diamond; you have to transfer it from FireRed/LeafGreen.
