That's an update. He wants an upgrade. That is to say, he wants to go from Extra A7 to Com A7, which is a step that requires money.

Truth, my prediction would be that this will probably be possible, though you'll (again, probably) have to contact the support to do so. This, err, is not a recommendation to send them a mail just yet - I'd wait for an official reply as well. I just wanted to fill this space with something perhaps useful to you. If not, my apologies.
(Also, I'm curios: Is there a specific reason you're not getting A8, or do you do it as it's (a final "probably") cheaper to upgrade A7?)


Perhaps this post will get me points for originality at least.

Check out Dungeon Deities! It's amazing and will make you happy, successful and almost certainly more attractive! It might be true!
