Plan and run a controlled, COMMUNITY-edition Harvester HCI upgrade off an EOL line up to latest stable — the no-skip minor ladder (1.5→1.6→1.7→1.8→1.9; embedded RKE2/KubeVirt/Longhorn/SLE-Micro ride along), gated at each hop on first upgrading the EXTERNAL Rancher + a matching Harvester UI-extension (1.6↔Rancher 2.12, 1.7↔2.13, 1.8↔2.14, 1.9↔2.15). Covers air-gapped version detection, why node-upgrade order is NOT operator-choosable (forced serial; the pause knob is v1.7.0+ only) and how to…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# harvester-upgrade Plan, sequence, and de-risk a **community-edition Harvester HCI** upgrade across a real fleet — typically off an **EOL line** (1.5.x) up to the latest *settled* stable. The hard part is almost never the ISO/UI upgrade click. It is the **coordination**: Harvester is one bundle whose embedded RKE2, KubeVirt, Longhorn, SLE Micro, and Rancher pairing all move together, the upgrade controller **picks its own node order**, and the workloads that matter most — VM-hosted Kubernetes control planes — must stay quorate while each host reboots underneath them. **Community editions only.** SUSE sells "SUSE Virtualization" (Prime) as a paid *support subscription on the same bits* — it is **not** a different artifact set, and **patch releases are community-downloadable** (House Rule #1). Flag Prime-only support claims; never build a plan on them. ## Companion to k8s-components-checker and rancher-upgrade — who owns what This skill is the Harvester-side upgrade-methodology companion in the same trio (`rancher-upgrade` SKILL.md explicitly defers Harvester host→guest coordination here). Respect the boundary to avoid drift: | Question | Skill | |----------|-------| …

How to install
mdr add air-gapped/skills/harvester-upgrade@sha256:9b21bfc436c16196The line at the top of this page pins the label git:20261027.a9dba19, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
