## Technical notes
### Legacy alerting -> Grafana Alerting dry-run on start
If you haven't already upgraded to Grafana Alerting from legacy Alerting, Grafana will initiate a dry-run of the upgrade every time the instance starts. This is in preparation for the removal of legacy Alerting in Grafana v11. The dry-run logs the results of the upgrade attempt and identifies any issues requiring attention before you can successfully execute the upgrade. No changes are made during the dry-run.
You can disable this behavior using the feature flag `alertingUpgradeDryrunOnStart`:
```toml
[feature_toggles]
alertingUpgradeDryrunOnStart=false
```

We strongly encourage you to review the [upgrade guide](https://grafana.com/docs/grafana/v10.4/alerting/set-up/migrating-alerts/) and perform the necessary upgrade steps prior to v11.
