Prerequisites

Latest [Dapr CLI]({{< ref install-dapr-cli.md >}})
Helm 3

Upgrade existing cluster running 0.11.x

Run these two commands to prevent helm upgrade from uninstalling 0.11.x placement service:

kubectl annotate deployment dapr-placement helm.sh/resource-policy=keep -n dapr-system

kubectl annotate svc dapr-placement helm.sh/resource-policy=keep -n dapr-system

Export certificates:
```
dapr mtls export -o ./certs
```

Upgrade Dapr to 1.0.0-rc.2:

helm repo update

helm upgrade dapr dapr/dapr --version 1.0.0-rc.2 --namespace dapr-system --reset-values --set-file dapr_sentry.tls.root.certPEM=./certs/ca.crt --set-file    dapr_sentry.tls.issuer.certPEM=./certs/issuer.crt --set-file dapr_sentry.tls.issuer.keyPEM=./certs/issuer.key --set global.ha.enabled=true --wait

Upgrade CRDs:

kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/configuration.yaml

kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/components.yaml

Ensure 0.11.x dapr-placement service is still running and wait until all pods are running:

kubectl get pods -n dapr-system -w

dapr-sidecar-injector-68f868668f-ltxq4   1/1     Running   0          36s

Restart your application deployments to update the Dapr runtime.
```
kubectl rollout restart deploy/<DEPLOYMENT-NAME>
```

Once the deployment is completed, delete the 0.11.x dapr-placement service:

kubectl delete deployment dapr-placement -n dapr-system

kubectl delete svc dapr-placement -n dapr-system

All done!

Upgrade existing cluster running 1.0.0-rc.1

Export certs:
```
dapr mtls export -o ./certs
```
