For .x upgrades yum can be used. But iso upgrades are recommended. What is the point having a homelab? So I will try the yum based upgrade. The official documentation can be found at https://xcp-ng.org/docs/upgrade.html#from-command-line . Login has root in your XCP-ng host (use ssh session) Set the VER variable to the version to upgrade to with the command: # export VER=8.2 Download the following files by executing the following commands: # wget https://updates.xcp-ng.org/8/xcp-ng-$VER.repo -O xcp-ng-$VER.repo # wget https://updates.xcp-ng.org/8/SHA256SUMS -O SHA256SUMS # wget https://updates.xcp-ng.org/8/SHA256SUMS.asc -O SHA256SUMS.asc Install the repository so that yum can use it by executing the following commands: # cp xcp-ng-$VER.repo /etc/yum.repos.d/xcp-ng.repo choose y to overwrite the file xcp-ng.repo #
