Requesting a certificate for your migrated properties

When moving your CDN services to Lumen, follow these guidelines to switch over your traffic without interruption to your customers.

To request a certificate for your migrated properties:

  1. Create a Let's Encrypt certificate. In addition to your common name and additional SAN domains, add a temporary property that will serve as a redirection point from your current CDN provider. (This is only temporary and can be removed after the certificate is provisioned.)
  1. Add the Lumen CName record to your DNS system for the temporary property only. To avoid interrupting your service, don't add any other CNames at this time.
  1. Create a property on a configuration (using the Let's Encrypt certificate you just created). Be sure that the primary alias matches the common name on the certificate and the secondary aliases match all SAN domains—including the temporary redirection property.
  1. Save the configuration, then promote it to production.
  1. If everything looks good, you can now cut over to Lumen by adding the remaining CNames to your DNS system.
  1. Remove the temporary property (no longer needed) from the certificate and property:

    1. Click Manage Certificates.

    2. On the row for the Let’s Encrypt certificate, click Regenerate LE.

    3. Remove the temporary property, then click Submit.

    4. Remove the corresponding secondary alias of the relevant property on the configuration that is presently serving production traffic.

    5. Save your changes and promote this newer version to production.
