Simply take the new Hubhopper Studio RSS link to your previous hosting platform and request for a 'Redirect'.
Most podcast hosting platform will have the option available under 'settings'. If not available, you can contact their support team and request for a '301 redirect'. The redirection process usually takes 2-3 hours to be completed.
This will link up the old RSS link to your new RSS link. This way, you do not have to go through the entire process of distributing your podcast again.
