# Upgrade VAST Block CSI Driver

## Steps to Upgrade VAST Block CSI Driver

Choose your upgrade path:

- To upgrade from 2.6.3 or later to 2.7.x:
  - Follow the [procedure](/develop/docs/upgrade-vast-block-csi-driver-27#upgrade-helmbased-deployment-of-vast-block-csi-driver) for upgrading a Helm-based deployment.
- To upgrade from 2.6.2 or earlier to 2.7.x:
  1. Delete all storage classes created via Helm in versions prior to 2.6.3 and recreate them via Helm so that the driver applies the `secretName` and `secretNamespace` settings to them (introduced in 2.6.3).
  2. Follow the [procedure](/develop/docs/upgrade-vast-block-csi-driver-27#upgrade-helmbased-deployment-of-vast-block-csi-driver) for upgrading a Helm-based deployment.

## Upgrade Helm-Based Deployment of VAST Block CSI Driver

Complete these steps to upgrade VAST Block CSI Driver:

1. Refresh Helm repository information to see which VAST Block CSI Driver versions are available for deployment:

```
helm repo update
```
2. Update the VAST Block CSI Driver's Helm chart configuration file (`values.yaml`) to specify the target release of the driver:

```
image:
  csiVastPlugin:
    repository: <repo>
    tag: <new release>
    imagePullPolicy: IfNotPresent
```

For example:

```
image:
  csiVastPlugin:
    repository: vastdataorg/csi
    tag: v2.7.0
    imagePullPolicy: IfNotPresent
```
  - `&lt;repo&gt;` is the name of the Helm repository.
  - `&lt;new release&gt;` is the driver release to be upgraded to.
3. Run Helm upgrade:

```
helm upgrade <old release> <repo>/vastblock -f <filename>.yaml
```

Where:
  - `&lt;old release&gt;` is the driver release to be upgraded from.
  - `&lt;repo&gt;` is the name of the Helm repository.
  - `vastblock` is the name of the driver's Helm chart.
  - `&lt;filename&gt;.yaml` is the Helm chart configuration file.
4. Verify the status of the new release:

```
helm ls
```
