2011 - 2012 upgrade question

Hey people.

 

I've been using NIS for the past 5 years or so and I didn't know about this upgrading to NIS 2012 from 2011 business until I stumbled upon it a few days ago by reading a few threads, such as these:

http://community.norton.com/t5/Norton-Internet-Security-Norton/Upgrade-NIS-2011-to-2012/m-p/499454/highlight/true#M165732

I'm very impressed!

 

My question is;

 

I try to keep my pc running smoothly and every so often (about 6-9 months ish) I re-install Windows and all the programs I use. Obviously by buying the disc based NIS I could just re-install that and download the updates but if I used this free upgrade and used a 2011 product code, can I still update it from the 2011 to 2012 when I do a fresh install? Or is this a one time only proceedure?

 

I don't want to buy it twice if it doesn't work like that!

 

Thanks
