+### Breaking changes when updating to unified alerting
+
+Grafana 8 alerts introduce a new way to manage your alerting rules and alerts in Grafana.
+As part of this change, there are some breaking changes that we will explain in details.
+
+#### Multiple Alerts in one payload
+
+As we now enable [multi dimensional alerting]({{< relref "../difference-old-new.md#multi-dimensional-alerting" >}}) a payload
+consists of an array of alerts.
+
+#### Removed fields related to dashboards
+
+Alerts are not coupled to dashboards anymore therefore the fields related to dashboards `dashboardId` and `panelId` have been removed.
+where removed. The removed fields are `dashboardId` and `panelId`.
+
 ## Manage contact points for an external Alertmanager
 
 Grafana alerting UI supports managing external Alertmanager configuration. Once you add an [Alertmanager data source]({{< relref "../../datasources/alertmanager.md" >}}), a dropdown displays at the top of the page where you can select either `Grafana` or an external Alertmanager as your data source.
