Deleting a Certificate Authority Version
Delete a certificate authority (CA) version when you no longer need it.
You can only delete a certificate authority version with a rotation state of deprecated. For a deprecated version to exist, a current version and a previous version must also exist. Unless you want to delete a certificate authority entirely, you must maintain at least one version of the certificate authority. When you delete a certificate authority version, the deletion doesn't happen immediately. By default, a certificate authority is permanently deleted 30 days after you schedule it for deletion. At minimum, the certificate authority continues to exist for another seven days.
