Can I upgrade from a Gold plan concierge client to a Platinum plan concierge client?

 In

Yes, you can upgrade at any time with no less than sixty days notice, provided you are not subject to any known or suspected VSP audit or, if you included State Board defense, any known or suspected State Board matter. Any upgrade restarts the 1-year (12 payment) requirement starting from the time the upgrade first takes effect (that is, from the first day of the current month).
