Comcast and subscription question

I currently have Norton Antivirus 2010 with 199 days left on my page subscription. With my Comcast account I was given a free copy of Norton 360. Windows 7 says I have to uninstall Norton Antivirus before I can install 360.

 

Question is this..

 

Will my paid subscription apply to Norton 360? Do I have to do anything to transfer it?

 

Thanks
