I need to change the event type from single event, recurring, or flexible to another type. How do I do this? Can I do this?
No, you can't change an event's type after it is published. You would have to delete the event and create a new one with the Event Type you want. Note that the system will notify anyone who has signed up that you have deleted the event. Therefore, you may want to communicate to everyone on the roster before you delete the event to let them know that you are creating a new one.
