Installing Norton Security Deluxe

I currently run Norton Security (ver 22 6 0 142 I believe) on a Windows 7 laptop. It expires in about 15 days. I have bought a card for Norton Security Deluxe (5 devices - although I am only using for one initially). I understand that to install I go to Norton.com/setup, enter the product key, and follow the on-screen instructions. My question is will I be able to install 'over' my existing product without taking any steps to 'stop' it or remove it first?

Regards,

Peter
