Move Payment to new site

Hi,

I built a website/store and linked a Woocommerce Payment gateway. I have been testing a few weeks and just migrated the site to a new home.

The issue I’m facing is the Woocommerce Payment Gateway is not showing in the Checkout.

I have turned off the plugin in the old website, but still nothing is working.

Is there a way to unlink the old site and connect to the new site?
