If you have forms 1.0 then yes.
When you create a new form as you name it you should see a dropdown box asking you to select forms 2.0 or form 1.0. If you don't see this it means that you started using Marketo after forms 2.0 was released so there is no real need to have access to forms 1.0 because 2.0 is simply way better 🙂
