Migrating payment and subscription data

I'm going to rebuild my multisite from scratch as I'm having issues with my current installation.
Can I get the configuration from Paypal/stripe/user account names and passwords manually copied over the new environment.
I will rebuild it under the same domain name. I'm using Pro Sites and Enom integration with Domain Mapping.
I don't want my clients to have to resubmit credit card info. Could you tell me which data I have to migrate in order to achieve this or if it's possible to migrate it at all?
