If you run the same event every year, duplicating saves you configuring it from scratch.
How to duplicate an event
On the dashboard, find the card of the event you want to duplicate
Open its options menu and click Duplicate
The duplication wizard opens, similar to the event creation one: review name, URL, dates, location and contact
Under Existing fees configuration you decide how the original event's fees carry over
Tick anything else you want to carry over; for example, the AI Assistant (Nico) configuration
Click Duplicate Event
What to review afterwards
Dates of the event and the registration period
Price periods of each fee (adjust them to the new calendar)
Texts and sections of the website that mention the previous edition
Discount codes: don't forget to create the new event's codes
Registered participants are not copied: the new event starts with zero registrations.
