How to transfer membership between sites?

Right now I have two WordPress sites running WooCommerce, including the WooCommerce Memberships and Subscriptions plugins.

I like WPRUS. I was able to successfully automate creation of a new user account on site B when signing up on site A. However, I’m having trouble with copying the membership details with the user.

Here is the desired functionality:

1. User purchases a subscription product on site A. (works)
2. User creates account on site A during the checkout process. (works)
3. The subscription grants access to a membership on site A. (works)
4. WPRUS creates a duplicate account on site B. (works)
5. WPRUS grants user access to a membership on site B with the same name as the membership on site A. (does not work)
6. Renewal of the subscription happens annually on site A. (works)
7. If the subscription is not renewed, the membership access is lost on site A. (works)
8. If the membership access is lost on site A, it should also be lost on site B. (haven’t tested because item 5 doesn’t work)

Mostly likely the problem is that I don’t know what the right meta description is for the user’s enrollment in the membership program and how to transfer this to the other site using WPRUS.
