You're not switching as much as you're adding! Those who already have a Luxe Box, will keep their Luxe Box as is, and aren't required to add this new benefit. But you are welcome to participate in this program in addition to your Luxe Box.
Simply choose the Unlock Benefits on the Membership X Homepage and become a Lashify X Member.
All Customers with Active Subscriptions who were part of the Luxe program will continue to have access to the Subscription Portal whether they choose to join Membership X or not.
