>**Note:** It is recommended to backup Grafana's database before enabling this feature. If you are using PostgreSQL as the backend data source, then the minimum required version is 9.5.
At startup, when the feature toggle is enabled, Grafana dashboard alerting is disabled and existing dashboard alerts are migrated into a format that is compatible with the Grafana 8 Alerting system. You are able to view these migrated rules, alongside any new alerts you create after the migration, from the Alerting page of your grafana installation.
Also notification channels are migrated to an Alertmanager configuration with the appropriate routes and receivers. Default notification channels are added as contact points to the default route. Notification channels not associated with any dahsboard alert go to the `autogen-unlinked-channel-recv` route.
Since `Hipchat` and `Sensu` are discontinued, they are not migrated to the new alerting. If you have dashboard alerts associated with those types of channels and you want to migrate to the new alerting, make sure you assign another supported notification channel, so that you continue to receive notifications for those alerts.
During beta, the migration of existing dashboard rules may change.
## Disabling Grafana 8 Alerting after migration
To disable Grafana 8 Alerting, remove or disable the `ngalert` feature toggle. Dashboard alerts will be re-enabled and any alerts created during or after the migration are deleted.
>**Note:** Any alerting rules created in the Grafana 8 Alerting system will be lost when migrating back to dashboard alerts
