All existing links, embed code, and digital deliveries on the legacy platform have seamlessly been transferred to the new platform and will continue to operate normally. No action is required on your end!
If you need to make any changes to videos or collections that were migrated from the legacy platform, this should be performed on the new platform. You can replace migrated videos and update migrated collections without issues. If you then also need to export the project to a legacy format, you will need to make the same changes on the legacy platform.
