The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: An embodiment includes a method for upgrading a network appliance while preserving existing data. Upon receiving an upgrade trigger, the network appliance downloads and stores an updated package containing at least a new kernel and a new ramdisk. The network appliance identifies the currently active image partition and the separate factory reset partition, then copies the updated kernel and ramdisk into the factory reset partition. The boot loader’s main configuration file is modified to direct the network appliance to boot from the updated factory reset partition. After rebooting, the appliance designates the updated partition as the new active image, enabling the updated kernel and ramdisk to mount installation scripts and complete the upgrade process without impacting stored data.
