NIS 2010 renewal

Hi,

 

I have a 3 PC version of NIS2010 due for renewal very shortly.

 

I've bought a new 3 PC NIS2011 box.

 

When the time comes exactly where do I enter the new licence code?

 

Also if I enter it on one of the PCs do I then have to enter it on the other two or does one update all three??

 

Many thanks,

Rowantree
