We get a lot of requests for the steps to convert to Paid Memberships Pro from other plugins. I just drafted a PDF outlining the steps for a conversion from s2Member® to Paid Memberships Pro. The guide is available as a PDF to PMPro Members and higher.
If you’re migrating from s2member to Paid Memberships Pro, here’s one additional step needed to ensure PayPal IPN data is sent and updated within PMPro.
Customize and add this code to your theme’s functions.php file or a helper PMPro Customizations plugin (our recommended method).
The code would be very similar for other membership plugins. If you need help crafting this IPN redirect for another plugin migration, post to the member forums.
