We have some registrations we need to move from one event to another. These are workshops where the attendees needed to transfer to a different one than they registered for. We need them to show up in the correct Attendee list, and be linked to the correct event for the purpose of follow up emails. We use Woocommerce. To change their event, we have re-opened their order in Woo, added the correct event to their order and deleted the old event. The order then shows the correct event registration. However, they still show up on the old attendee list. I believe we can still manually delete them from the original attendee list, but is there a way to add them to the new Attendee list?
