              Recommended for:<\/strong><\/h3>
              • Users who want to use the latest features and are able to accept more frequent host reboots.<\/li>
              • Individuals working with Windows 11 on virtual machines.<\/li>
              • Administrators who need PCI passthrough functionality or advanced migration options.<\/li><\/ul>

                Avoid upgrading if:<\/strong><\/h3>
                • You are using nested virtualization (temporarily not working in 8.3).<\/li>
                • You are using para-virtualization (PV) - it is not supported in this version.<\/li>
                • You have critical environments that do not tolerate frequent reboots, in which case staying with version 8.2 LTS will be a better choice.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                  1. Preparing for the update<\/strong><\/h3>
                  • Back up your data (backup and backup test).<\/li>
                  • Make sure you have the latest version of XCP-ng 8.2.1 with all current patches.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                    2. Update process<\/strong><\/h3>
                    • Download the ISO image of XCP-ng 8.3 and create a bootable USB.<\/li>
                    • Restart the server and run the installation from USB.<\/li>
                    • The installer automatically backs up your configuration, but it's a good idea to make sure you back up beforehand.<\/li>
                    • Follow the installer's instructions (the process is simple: mostly confirming settings).<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
