## Motivation *ggardet_arm* suggests to upgrade openqa-aarch64 to Leap 15.2 soon so that he run some qemu >= 4.0 aarch64 specific tests. Also having one machine machine in production upgraded can help us to find early problems. ## Acceptance criteria * **AC1:** openqa-aarch64 (o3) runs a clean upgraded openSUSE Leap 15.2 (no failed systemd services, no left over .rpm-new files, etc.) ## Suggestions * read https://progress.opensuse.org/projects/openqav3/wiki#Distribution-upgrades * Reserve some time when the worker is only executing a few or no openQA test jobs * Keep IPMI interface ready and test that Serial-over-LAN works for potential recovery * Use the instructions from above but use `transactional-update dup` or `transactional-update` to do the upgrade * After upgrade reboot and check everything working as expected, if not rollback, e.g. with `transactional-update rollback` * Document in parent ticket so that we keep the learnings in mind for other machines ## Further details * Don't worry, everything can be repaired :) If by any chance the worker gets misconfigured there are btrfs snapshots to recover, the IPMI Serial-over-LAN, a reinstall is possible and not hard, there is no important data on the host (it's only an openQA worker) and there are also other machines that can run aarch64 jobs while this host might be down for a little bit longer. And okurz can hold your hand
