To redirect you series away from ART19 you'll first need your RSS Feed URL from your new hosting platform. Consult our help center article on migrating off 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 - fill out our series redirect form. After we have confirmed that the redirect(s) is placed, we will take down the profile(s) about 24 hours later (you will retain access to your stats accumulated during your time hosted on ART19), but the redirect will stay in place indefinitely.
