import paypal transaction data into membership

Hi, we're continuing our quest to move from S2Member to Membership.

Membership is running fairly well now for a couple of weeks, however PayPal IPN is not able to update any members transactions that occurred before the cutover to Membership.

So, we'd like to try to import the PayPal data from all previous transactions into the database, but need to get some details from you guys about what fields in what tables need to be populated.

We did do a database export before the cutover and we also have all the data stored as csv.

So, are you able to provide the details of what fields in which tables get updated when a PayPal transaction occurs?

If possible, can you please split this between a new membership signup purchase and a recurring transaction.

Thanks very much!
