The current ACME-client-based support for automated certificate management has been enhanced to support using both LetsEncrypt and DigiCert as an ACME Certificate Authority (CA) in the same deployment. In previous releases, only certificates from one CA could be managed.

If you have certificates from an ACME CA before you upgrade, those certificates are preserved. After upgrade, the UI page for selecting a CA re-appears; select your current CA provider to see your current certificates.
