Looking to copy over a dashboard template via json but struggling to find a solution to this error Failed to upgrade legacy queries Datasource prometheus was not found does someone know what this means or what I should change in the template? :eyes:

I also bumped into this issue. Have you managed to resolve this out ?

no I havent, I read something in a github issue that a dashboard UID is needed but no clear answer how to get that exactly :thinking_face:

I figured out my error, what I needed to do was to change ALL the datasources in the json, I was only changing the one at the top. I changed all the datasources NOT labeled "null" (leave those)…and changed the datasources from prometheus to Mimir (capital M), then grafana was happy. :slightly_smiling_face: example below:

      "list": [
        {
          "builtIn": 1,
          "datasource": "Mimir",
          "enable": true,
          "hide": true,
          "iconColor": "rgba(0, 211, 255, 1)",
          "name": "Annotations & Alerts",
          "type": "dashboard"
        }
      ]
    },```
