we plan to change the domain name for our service. Therefore we need to update the IPN-url for our existing customers. I have tried googling a solution on how to change the IPN-url for current subscriptions, but I haven't been able to find anything.

Any help is appreciated.

best regards Thomas

I ran into this problem today.

Folks who are saying that you can change the IPN URL on an existing Paypal recurring payment are incorrect; you can't, you can only change the IPN URL for future notifications.

To resolve this, I used an Apache rewrite:

RewriteRule ^sites/all/modules/civicrm/extern/ipn.php$ https://example.org/wp-content/plugins/civicrm/civicrm/extern/ipn.php [R=307,L]

The magic is the R=307. A 307 redirect indicates that a POST request must be resent as a POST. Otherwise you lose the IPN data.
