As per title, we shall upgrade to Grafana 7.
Grafana 7.1.3 is available at https://grafana-next.wikimedia.org for testing.
Please note that dashboards are currently not synced from https://grafana.wikimedia.org to not overwrite the Grafana 7 DB schema.
- Test (with database sync disabled) Grafana 7 on https://grafana-next.wikimedia.org
- Manually sync the database once more before transition
- Point grafana.w.o to the same place as grafana-next.w.o and announce the change, wait for feedback. Note that ATM this also means failing over Grafana to codfw
- Once things are working ok, upgrade the (now standby) host that was running Grafana 6 to Grafana 7
- Turn back on database sync
- Fail back to eqiad
