Plan and run a controlled, COMMUNITY-edition Grafana Mimir upgrade on the `mimir-distributed` Helm chart, air-gap first — the chart↔app co-pinned ladder (5.7→5.8→6.0.6→6.1.0 = app 2.16→2.17→3.0.4→3.1.2), the classic-vs-ingest-storage decision (the chart ships a supported `classic-architecture.yaml`; `kafka.enabled: false` alone is NOT the switch and causes an ingestion outage), the community-specific nginx→gateway rename that silently moves the proxy's DNS name and breaks every remote_write…
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
# mimir-upgrade Plan, sequence, and de-risk a **community-edition Grafana Mimir** upgrade deployed via the `mimir-distributed` Helm chart, in an **air-gapped** environment. The hard part is not `helm upgrade`. It is that chart 6.0 changes the **write-path architecture**, the **proxy's DNS name**, and the **admission-webhook posture** all in one hop — and the chart validates none of the operator's stale values, so most of the damage is silent. **Community editions only.** Ignore Grafana Enterprise Metrics (GEM) gating; the whole GEM values surface is removed from the chart at 6.0 anyway. ## Evidence tags — do not flatten these Every claim in this skill is tagged: - **[UG] upstream-grounded** — a doc, changelog, release note, or source file says it. - **[RFC] reasoned-from-config** — derived by reading chart templates, values, or Go source. Both tags mean *researched*. The grounding runs to tagged upstream source (`help-all.txt.tmpl`, `config-descriptor.json`, `pkg/ingester`, `pkg/usagestats`, `pkg/storage/ingest`), kubectl's and Helm's own source, both CHANGELOGs, the docs, and six issues cited as evidence of absence. Two claims were settled by …

How to install
mdr add air-gapped/skills/mimir-upgrade@sha256:250d2be8939dc86fThe line at the top of this page pins the label git:20261027.17a2f9c, 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.
