How to connect installed NIS to a new Norton account?

I am responsible for NIS on three computers at our church. The current license expires later this week. I have already purchased a new 3 computer license key and will enter it later this week. I currently have my personal Norton Acount attached to these 3 computers and would like to move their attachment to a new Norton Account when I renew the license. I have created the new Norton Account already. Could somebody tell me how to ensure I get the 3 installations attached to the new account when I enter the new key?

Thanks, Mike
