Bring it into your local Verizon store. Ask them to do an equipment swap to the N6. It'll take 10 minutes if the clerk has no idea what to do. (It takes about 2 minutes normally, almost all of which is typing and waiting for the computer, then calling the phone to make sure everything worked.) What do you do? Stand there and be bored.
Oh, ask them how much of your current phone's data they can transfer to the N6. Most stores have a little black box these days that can transfer a lot more than contacts (which, if you entered them as Google contacts, which you should, will automatically sync to the new phone by themselves).
