Julien Roberge - Welcome to Microsoft Q&A and thanks for reaching out to us. At this moment, Azure Managed Grafana Upgrade from 9 to 10 is currently unavailable and the product team has confirmed that it will be available in the next couple of months. What you can do right now is you need to create a new Managed Grafana instance with version 10 and migrate their dashboards over or else you can wait until the upgrade is available. Hope this helps. and please feel free to reach out if you have any further questions.
