Your 6 has its own nano sim that is now activated for that number.
To go back to the 4s you either need a nanosim to microsim adapter or to go to an AT&T store and get a microsim provisioned to put back in your 4s.
When you activate your new 6 the old one is killed, can't have two phones with the same number. The new 6 has its own sim
Wtf?? I can't just switch back to my 4S?? That's ridiculous, why the hell would they do this?

Why didn't anyone warn me of this? That's ridiculous, what if I want to switch back and forth?

If you want to switch back and forth then you'll need to switch the SIM (and you'll need an adapter). That's pretty standard; it's rare for two phones to share the same number (there used to be a service called Tandem here but it was discontinued several years ago, and even then it only supported voice).
Jesus. The adapter kits are on eBay and Amazon and are under $10. Only one SIM card can be assigned one number at a time. If you wanna use your 4S, you will need to put the nano SIM card into the adapter and pop it into the 4s.
No kidding right? People seem to be coming out from under their rocks lately.
Just look at his previous posts for the answer, I'm surprised they haven't banned him and even more surprised people keep replying to his posts.
yea no kidding
Wtf are you talking about? Almost all of my posts are completely legitimate questions/observations.

What because I has a 4S that had the old kind of SIM card? I bet most normal people don't know about this.
Is OP pulling a fast one? Or is OP dumber than a bag of rocks?
How am I dumb because my previous phone used an older technology? How the hell would I know about the technology for other phones?
Is this the first time you've gotten a phone with a different sim? Was the 4s your first ever phone?
Yup, first smart phone
Yes but when you transferred to the 4s if you had a normal phone before it, the same thing would have happened.
Well at this point you're question has been answered. You live and learn. This thread has run its course IMO.
