It is definitely the thing to do, it gives you a chance to use sand to level and have a solid base to pour on.

I know people who tried to pour over existing concrete to save a $, but you end up with the same result sooner or later, busted driveway.

To try and even do it right is very labor intensive, drilling through existing concrete and and driving rebar for extra support, not worth it.

If you do your driveway, and demo the existing concrete, don't let whoever you get to do it fool you. Don't let them try to charge you extra for the "disposal" of the concrete, either they grind it up and reuse it themselves or they sell it to someone who does it. People are buying this crushed reclaimed concrete instead of limestone, it is cheaper and packs better than limestone.

Even if you resurface with asphalt, demo the existing concrete.

Good Luck, hope this helps!
