Quick note: Only the current Event Owner can change the page ownership.
1. Head to the Settings tab on the event page toolbar.
2. Click on the Collaborators sub-tab.
3. Select the options button on the card for the collaborator you'd like to transfer ownership to.
4. Click Set as Event Owner in the menu that opens up.
5. Click the Save button.
