Is there, like an official procedure for exchanging iPhone with a new iPhone?

I have a 16gb iPhone 6(near mint condition). I'm not too happy with 16 gb. I'm however, very excited for the iPhone se version that is coming out. Is there some kind of procedure where I can exchange my 6 for a se version?

. There's no "official" procedure. Ask your carrier

Yes, the procedure is you buy the new phone then sell your old phone however you want.

Depends on what store(s) are your options.

Most these days have trade in options

You buy the new phone, transfer what you want from the old phone to the new one. Delete all your personal information and data from the old phone, factory reset and sell the old phone.

But unless Apple or your carrier has an trade in program for some sort of discount on a newer phone, it is full retail for the new one.

Consult your nearest apple store for better guidance and if you need some advanced security, Leo Privacy would be the best.
