You can copy cards to different decks, and yes, individual card progress should get carried over as this data is stored with the card.
You can copy cards in the card listing screen. Tap Mode, multi-select, Mode, select all, Mode, Copy...
I would choose one of your decks to receive your cards. But to be safe, I would backup this deck first. Export your deck to say Email (with statistics) by tapping Edit at Decks screen, tap deck, Export/Share...
Or you can create an Empty deck and move there, and re-setup the deck settings.
