Users should ensure all previously released errata relevant to their system are applied before upgrading. If the Operator's installation approval policy is set to Automatic (default), the upgrade will occur automatically with no further action required. If set to Manual, users must approve the upgrade manually. Refer to the official Red Hat documentation for detailed upgrade instructions: https://docs.openshift.com/container-platform/latest/security/cert_manager_operator/index.html.
