supscription not going through or processed when the site is live

[AmaniAmanZwayen]

Hi there,
So I'm using your plugin to export and import subscribers from site to site,
first: not all the details were imported or exported in a good way.
second thing, I went live and waited for 4 hours and none of the subscriptions went through nor processed, what exactly had I missed? what exactly should I do to make the subscription go through once the site is live?

and one question, I know as long as the site is staging all the payment method is set to manual,
I'm just wondering when we go live these methods automatically change to credit card ... or we should change it manually?
and will it fetch the payment method and tokens ???

thanks
