Migrating membership subscriptions from Bold Memberships

Does FluentCart support migrating Membership subscriptions from another platform? In my case, the client has memberships with Bold Memberships (using Stripe payment gateway): https://boldcommerce.com/shopify/bold-memberships

Bold Memberships support says: "Unfortunately, there is no migration pathway available to migrate existing memberships from Bold to another platform.
However, you will be able to get the Stripe tokens directly from Stripe."

Do you have any documentation on how to achieve this?
