+## Migrate from Flux v1
+
+If you've been using Flux v1 in Azure Arc-enabled Kubernetes or AKS clusters and want to migrate to using Flux v2 in the same clusters, you first need to delete the Flux v1 `sourceControlConfigurations` from the clusters.  The `microsoft.flux` cluster extension won't install if there are Flux v1 `sourceControlConfigurations` resources in the cluster.
+
+Use these Azure CLI commands to find and then delete existing `sourceControlConfigurations` in a cluster:
+
+```azurecli
+az k8s-configuration list --cluster-name <Arc or AKS cluster name> --cluster-type <connectedClusters OR managedClusters> --resource-group <resource group name>
+az k8s-configuration delete --name <configuration name> --cluster-name <Arc or AKS cluster name> --cluster-type <connectedClusters OR managedClusters> --resource-group <resource group name>
+```
+
+You can also use the Azure portal to view and delete existing GitOps configurations in Azure Arc-enabled Kubernetes or AKS clusters.
+
+More information about migration from Flux v1 to Flux v2 is available in the fluxcd project: [Migrate from Flux v1 to v2](https://fluxcd.io/docs/migration/).
