If I switch to a custom domain, is it easy to set up a redirect?

Thanks! Do you think “we’ll take care of the rest” includes setting up a redirect from the old example.discourse.group to forum.example.com then?

(It’s not obvious to me, particularly as that guide seems to be talking about customers starting fresh on the Standard Plan or above, rather than moving from a .discourse.group domain on the Basic Plan to a custom domain on a Standard Plan while trying to keep the domain pointing to the same forum.)
