Norton Renew Question

Greetings:

 

In Feb '10 I downloaded a 12 month subscription of NIS 2010. When Jan of '11 came I was able to upgrade over the internet my NIS 2010 to NIS 2011, HOWEVER, the original 12 month subscription ends tonight at Midnight.

I purchased a retail copy of NIS 2011 earlier. I know about the product key, but would I have to uninstall all of the Norton files that are due to expire I have on my laptop before I can load the new NIS 2011?

 

Thank you
