Delegate SSL certificates for already delegated subdomains
To delegate SSL certificates for an already delegated subdomain, click the ellipsis button next to the desired subdomain and click Switch to Managed SSL.
A dialog box displays with the certificate records that have been automatically generated by Adobe. Copy these records, either one by one, or by downloading a CSV file, then navigate to your domain hosting solution to generate the matching certificate.
Make sure that all the certificate records have been generated into your domain hosting solution. If everything is configured properly, confirm the records creation then click Submit.
