Can I change my payment widget and retain data?

I want to change my payment widget to Paypal. Can I keep all the data I currently have in my payment option? Is there a button to just turn on paypal?

Thank you!

I see that your JotForm is configured with Purchase Order payment method. Since you have already received some submissions to the form and when you delete the payment field on the form, the field associated data will also be deleted. So, it is suggested to clone to the form to your account and then delete the Purchase Order field on the form to add the PayPal field on the cloned form. 

Thank you!
