## Prerequisites
- [Dapr CLI]({{< ref install-dapr-cli.md >}})
- [Helm 3](https://github.com/helm/helm/releases) (if using Helm)
## Upgrade existing cluster to {{% dapr-latest-version long="true" %}}
There are two ways to upgrade the Dapr control plane on a Kubernetes cluster using either the Dapr CLI or Helm.
{{% alert title="Note" color="primary" %}}
Refer to the [Dapr version policy]({{< ref "support-release-policy.md#upgrade-paths" >}}) for guidance on which versions of Dapr can be upgraded to which versions.
{{% /alert %}}
### Dapr CLI
The example below shows how to upgrade to version {{% dapr-latest-version long="true" %}}:
```bash
dapr upgrade -k --runtime-version={{% dapr-latest-version long="true" %}}
```
You can provide all the available Helm chart configurations using the Dapr CLI.
See [here](https://github.com/dapr/cli#supplying-helm-values) for more info.
#### Troubleshooting upgrade using the CLI
There is a known issue running upgrades on clusters that may have previously had a version prior to 1.0.0-rc.2 installed on a cluster.
Most users should not encounter this issue, but there are a few upgrade path edge cases that may leave an incompatible CustomResourceDefinition installed on your cluster. The error message for this case looks like this:
```
❌ Failed to upgrade Dapr: Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
The CustomResourceDefinition "configurations.dapr.io" is invalid: spec.preserveUnknownFields: Invalid value: true: must be false in order to use defaults in the schema
```
To resolve this issue please run the follow command to upgrade the CustomResourceDefinition to a compatible version:
```
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/5a15b3e0f093d2d0938b12f144c7047474a290fe/charts/dapr/crds/configuration.yaml
```
Then proceed with the `dapr upgrade --runtime-version {{% dapr-latest-version long="true" %}} -k` command as above.
### Helm
From version 1.0.0 onwards, upgrading Dapr using Helm is no longer a disruptive action since existing certificate values will automatically be re-used.
1. Upgrade Dapr from 1.0.0 (or newer) to any [NEW VERSION] > 1.0.0:
*Helm does not handle upgrading CRDs, so you need to perform that manually. CRDs are backward-compatible and should only be installed forward.*
>Note: The Dapr version is included in the commands below.
For version {{% dapr-latest-version long="true" %}}:
```bash
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v{{% dapr-latest-version long="true" %}}/charts/dapr/crds/components.yaml
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v{{% dapr-latest-version long="true" %}}/charts/dapr/crds/configuration.yaml
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v{{% dapr-latest-version long="true" %}}/charts/dapr/crds/subscription.yaml
kubectl apply -f https://raw.githubusercontent.com/dapr/dapr/v{{% dapr-latest-version long="true" %}}/charts/dapr/crds/resiliency.yaml
kubectl apply -f https://raw.githubusercontent.com/dapr/dapr/v{{% dapr-latest-version long="true" %}}/charts/dapr/crds/httpendpoints.yaml
```
```bash
helm repo update
```
```bash
helm upgrade dapr dapr/dapr --version {{% dapr-latest-version long="true" %}} --namespace dapr-system --wait
```
*If you're using a values file, remember to add the `--values` option when running the upgrade command.*
2. Ensure all pods are running:
```bash
kubectl get pods -n dapr-system -w
NAME READY STATUS RESTARTS AGE
dapr-dashboard-69f5c5c867-mqhg4 1/1 Running 0 42s
dapr-operator-5cdd6b7f9c-9sl7g 1/1 Running 0 41s
dapr-placement-server-0 1/1 Running 0 41s
dapr-sentry-84565c747b-7bh8h 1/1 Running 0 35s
dapr-sidecar-injector-68f868668f-6xnbt 1/1 Running 0 41s
```
3. Restart your application deployments to update the Dapr runtime:
```bash
kubectl rollout restart deploy/<DEPLOYMENT-NAME>
```
4. All done!
#### Upgrading existing Dapr to enable high availability mode
Enabling HA mode in an existing Dapr deployment requires additional steps. Please refer to [this paragraph]({{< ref "kubernetes-production.md#enabling-high-availability-in-an-existing-dapr-deployment" >}}) for more details.
