Question about the 3 map packs and a new Xbox

OK so I just got a new Xbox 360, and am using cloud storage to move my memory. But it won’t let me store any of my online pass. Will I be able to get the 3 map packs again

Yes…if you re-buy them.

OK I was able to dowmload the War Games Download pass it was in my recent downloads. Here is another question that might be a little dumb but who cares. When it comes time to dowmload the other 2 map packs will it show that I downloaded war games twice and not give me me the maps because they think I downloaded the war games map pass for someone else?
