You can't.
Rayquaza is not in Diamond only in the pokedex. You would need to migrate it from a gameboy advanced game.

The reasons why your Rayquaza isn't migrating to Diamond could be the following reasons: 1. Your Diamond game card or your Ruby game pak could be fakes. 2. You haven't unlocked the migration feature in "Diamond" yet. or 3. Your Rayquaza knows a HM such as Fly or is holding mail.
