You trade Pokemon from Pokemon Heartgold and Soulsilver to Pokemon Diamond by going to the wifi room in the Pokemon center on the top floor. You also need to have a copy of Pokemon Diamond and have to have a friend or someone who has a copy of Pokemon Heartgold or Soulsilver. You will see someone there if you are going to trade with someone. Talk to the person you are going to trade with and ask them if they want to trade. The top floor is the Union Room no Friend Code needed the basement is the Wi-fi room, which requires a Friend codes

You use the elevator if you finished seeing Whitney in the top. If you haven't you won't enter the room. If you haven't saw Whitney in the top use the ladders and battle the trainers in the way to get to the top.

You have to have a friend with Pokemon HeartGold who is willing to lend/trade the Blue Orb to you. In Pokemon SoulSilver, you will receive the Red Orb from Mr. Pokemon after defeating Red at the top of Mt. Silver.
Arceus does not appear in heartgold or soulsilver so you got to know the only way is to trade it from Pokemon diamond pearl and platinum and you need to get an azure flute and go on top of mt coronet and go into the hall of origin where arceus is waiting for you.
(This is for both Heartgold and Soulsilver) You must beat Red at the top of Mt. Silver, then go to Mr. Pokemon's house (Between Violet City and Cherrygrove City) and he will give you the Blue orb/Red orb depending what game you have.
