I would like to upgrade Norton Security from Standard (one device) to
Deluxe (five devices). Despite my efforts on the Norton website, I
have been unable to find any obvious way to do this. There is a claim
that if you renew early the renewal is added on to the remaining
subscription period. However, if I renew as Deluxe will my existing
subscription be converted immediately or not until the renewal date?

Another option seems to be to cancel automatic renewal thus forcing
expiry of the product then to make a new purchase at that stage..
Given the introductory offers that seem to be available, this could
end up cheaper if I am prepared to wait.

Is there any easy way to make this change?
