An easier solution might be to get in touch with the customers who have purchased the subscription via PayPal and ask them to switch their payment option to Stripe.
]]>Thanks for your response, I have contacted Paypal who have confirmed that the renewal dates cannot be changed on Paypal standard, and the only way would be to cancel the subscription and sign up again. Alternatively with the option you recommended, are the subscribers able to switch payment method from Paypal standard, do they allow this?
]]>Your customers can switch payment methods from their My Account page.
