I’m migrating from a WordPress site where I use Paid Membership Pro with stripe and PayPal as the payment gateways. Is there a way to transfer memberships to Ghost?
If not, can I manually set members up and give them a “paid” membership for free that requires them to renew on a certain date? This would allow me to keep there memberships matching to what they’ve already paid for. Our memberships are all time based (monthly or annually).
Hi, and welcome to the forum! 
Does Paid Membership Pro use Stripe Subscriptions? To check, in Stripe, you should see every paid subscriber like this.
If so, you should be able to export the list of subscriptions as a CSV and import it into Ghost, being careful to map the column names correctly.
Alternatively, you can create a new CSV file with the email & Stripe ID columns, add every subscriber to that, and then import that.
email,stripe_customer_id
name@example.com,cus_12345678
The email & Stripe Customer ID columns are key in both methods. Ghost will relate the two together, so the subscription for cus_12345678 will belong to name@example.com.
If that doesn’t work, or if Stripe is not using subscriptions, let me know, and I’ll detail other methods you can use to manually add them.
