Have NIS 09 - How to get 10?

I have Norton NIS 09 that I have never installed because I'm running Win7 x64. I've been using beta up until today. How can I get NIS 10 to install with my 09 product keys? If I install 09 and upgrade it will it be a clean install?

 

I saw the option to get the trial version but I have never heard of a company requiring a credit card to get a trial version. I'm not about to go that route.
