Export without scheduling data, delete, then import. That's the standard advice given to "restart" a deck in its entirety.
uisukii, unless I didn't understand your intent, it doesn't sound like you need a copy of the same deck. Since the underlying notes are exactly the same, you should be creating a new card type and present the fields in a different way. The cards generated won't share scheduling data with the existing cards, and you can move them into their own deck after they are generated (filter by card type, select all, click change deck button).
