Can i upgrade my iPhone 4s to an Iphone 5s?

I still have a few more months on my contract with Verizon, I started the contract in July of 2012 and I have had my iPhone 4s since then. I'm still about 5-6 months away from the contract expiring but would it be possible to upgrade to the iPhone 5s without being out of my contract?

Anyone can upgrade. The problem with upgrading during your contract is that you would have to deal with an early termination fee.
