Hi there, If you'd like some help with that, please contact support directly with the old webinar registration link, and the new ID. We may be able to import those for you, due to the extreme circumstances of the disruption today.
Hi Jane, I've processed the request to migrate these registrants from the old webinar to the new one. If this isn't possible, there is an alternate method that will work through a 3rd party service called Zapier. We will update you once we know how to proceed.
