# Upgrade

## Before Upgrade

Before proceeding with the upgrade, it's crucial to apply the specific prerequisites associated with your current version of NVIDIA Run:ai and every version in between up to the version you are upgrading to.

## Helm

NVIDIA Run:ai requires [Helm](https://helm.sh/) 3.14 or later. Before you continue, validate your installed helm client version. To install or upgrade Helm, see [Installing Helm](https://helm.sh/docs/intro/install/).

{% hint style="info" %}
**Note**

Helm 4 defaults to [server-side apply](https://helm.sh/docs/overview/#server-side-apply) when installing a new chart release, which can conflict with resources managed by the NVIDIA Run:ai operator. Append `--server-side=false` to your `helm upgrade` command. NVIDIA Run:ai clusters originally installed with Helm 3.x are unaffected.
{% endhint %}

## Software Files

```
helm repo add runai-backend https://runai.jfrog.io/artifactory/cp-charts-prod
helm repo update
```

## Upgrade Control Plane

### System and Network Requirements

Before upgrading the NVIDIA Run:ai control plane, validate that the latest [system requirements](/multi-tenant/2.23/getting-started/installation/cp-system-requirements.md) and [network requirements](/multi-tenant/2.23/getting-started/installation/network-requirements.md) are met, as they can change from time to time.

### Upgrade

To upgrade run the following:

```
helm get values runai-backend -n runai-backend > runai_control_plane_values.yaml
helm upgrade runai-backend -n runai-backend runai-backend/control-plane --version "<VERSION>" -f runai_control_plane_values.yaml --reset-then-reuse-values
```

{% hint style="info" %}
**Note**

To upgrade to a specific version, modify the `--version` flag by specifying the desired `<VERSION>`. You can find all available versions by using the `helm search repo runai-backend/control-plane --versions` command.
{% endhint %}
