Question for indie that sold a project

Hello,

I have a question for indiehackers that sold their project.

I have a side project that I want to sell. Whatever the actual MRR, my question is about the users' payment :

For now, users is paying every month (recurring payments), based on my PayPal account / stripe account.

So let's say I'll sell the project, I'll give all the code, the buyer will specify in the admin area his PayPal/stripe API, but what happens for the actual users' recurring payment? Is-it possible to "push" the recurring payment to another paypal/stripe account?

Because obviously, I can't also give my PayPal/stripe account.

Thanks for any help/hints
