free mini session vs paid 6 part program

Is the mini session supposed to be exactly the same as the 6-part program but with less information? If it is, how do you not give away everything for free on the coaching sessions? Only covering one module doesn’t seem like it would offer enough of a change to make my clients want to pay for more. Am I supposed to create two programs and some how lead the free mini session into what the paid program will offer? Wait. I just remembered the mini session is only one hour. The same program just might work. I would still like your thoughts. Thank you!
