Crossposting is a great way to use your live videos across multiple Facebook Pages. Crossposting still works after the Facebook Live Online Events Update, however, you can only crosspost once you are live. You cannot crosspost a scheduled stream until it has gone live. In order to create a crossposting relationship, you must be an Admin (Facebook Access) of your Facebook Page. These steps will not be available to other Page Roles.
1. Head to your Facebook Page settings and click "Videos."
2. Scroll down to "Crossposting" and add the Facebook Page or Pages you'd like your live streams to be crossposted to.
3. Click "Next".
4. Click "Done." Your stream should now be crossposted on Facebook!
