Users should ensure all previously released errata relevant to their systems are applied before upgrading. If the operator's approval policy is set to Automatic (the default), the upgrade to the patched version will occur automatically without user intervention. If set to Manual, users must manually approve the upgrade. Refer to the official Red Hat documentation for detailed upgrade instructions.
