To redirect you series off ART19 you'll first want to make sure you have your RSS Feed URL from your new hosting platform. Consult our help center article on migrating off of ART19 here for additional support and context on the entire process of moving off of ART19.
Once your series is imported to your new hosting platform and you have the new RSS Feed - reach out to firstname.lastname@example.org requesting a redirect to your new RSS Feed. Please include all profile names and all feeds if more than one needs to be redirected. Also include a target date and time. After we have confirmed that the redirect(s) is placed, we will take down the profile(s) about 24 hours later, but the redirect will stay in place indefinitely.
