The membership management system that we use is mainly manual when it comes to any changes that need to be made. Changes are difficult, time-consuming, or impossible. There is no system in place to allow for upgrades or downgrades. We are also not allowing previous signups to count for giveaway entries. If we do it for one person we have to do it for everyone. And then who decides how far back we allow it? It's just not feasible so we have to stand firm on it.
If you want to upgrade to HEX PLUS from HEX LITE we simply ask that you pay for a separate membership and forfeit your LITE membership. We can then cancel the auto-renew for the LITE.
More info on the details can be found on our Membership FAQ Page.
