Moving Norton Antivirus, etc., to a new machine

I currently have three computers with NAV installed - 1 desk top and 2 laptops.  The laptops are being replaced/upgraded.  I want to know how tomove the subscriptions from the 2 old Laptops to the 2 new ones.

 

I have tried signing in to my Norton Account, but, for some reason, all it recognizes is my new computer, which has a "trial" copy of Norton installed.  It does not seem to know that I have 3 installations on the existing computers.

 

What is the process

 

Thanks.
