How can we change the Google account that is set as the event owner for all SchoolCal-created events?

Before you change the Google account that is the event owner for SchoolCal-created events, we recommend that you delete all of the previously created SchoolCal events. One easy way to do this is to unselect all school levels on the SchoolCal filters page. 

Then save and re-sync. This should delete all future SchoolCal-created events so that events are not duplicated once the event owner account is changed. If you would like to delete all events (not just future events), you will need to select the "Update events that occurred in the past" option within the Meeting dates filter on the SchoolCal filters page as well.

To change the Google account that is set as the event owner for all SchoolCal-created events, go to the Data sink tile of the SchoolCal settings page, select edit next to the current event owner, select a new account from the dropdown, and save. Reselect the school levels for which events should be synced on the SchoolCal filters page, save, and re-sync. If you adjusted the "Update events that occurred in the past" option on the SchoolCal filters page, you will want to readjust it now.
