Changing Norton account with renewal

Currently we have 2 PC's in the house both under my daughters Norton account.

I will be buying Norton Deluxe (key) shortly ready for when they expire in early January. What I would like to do is renew both machines and switch the associated Norton account to me.

Can I just renew with the new key and change accounts at the same time or is it a complete uninstall/reinstall?

Thanks
