Is there a way to get your pokemon from 1st and 2nd generation pokemon games onto Diamond?

I was wondering because I really want all my pokemon from my blue and crystal games onto my diamond. If you have an answer it would be greatly appreciated, thanks. ^^|||no, I know what you mean though. :(|||No, but you can get them from pokemon emerald, but you have to COMPLETLY beat the game,|||get an action replay, you can get any pokemon u want in any grass you want and any level you want.
