# How to Upgrade Buildpacks in App Platform

App Platform is a fully managed Platform-as-a-Service (PaaS) that deploys applications from Git repositories or container images. It automatically builds, deploys, and scales components while handling all underlying infrastructure.

On DigitalOcean, we automatically upgrade all buildpacks to the latest minor version. However, if an upgrade causes errors, you must manually upgrade the app’s buildpacks (including those of its components) to the latest major version.

To upgrade buildpacks, use one of the following methods:

1. Upgrade [each buildpack individually](#upgrade-individually).
2. Upgrade [all buildpacks simultaneously](#upgrade-all).

**Warning**: Upgrading a buildpack may introduce errors in your app, depending on the changes in the new version. If an upgrade causes a deployment error, you can [roll back to a previous deployment](https://docs.digitalocean.com/products/app-platform/how-to/manage-deployments/index.html.md#roll-back-to-a-previous-deployment). For more information, see the [buildpack documentation](https://docs.digitalocean.com/products/app-platform/reference/buildpacks/index.html.md).

### Upgrade Individually

To upgrade buildpacks individually, go to the [**Apps** page](https://cloud.digitalocean.com/apps) and select your app. On the **Overview** page, scroll to the **BUILDPACKS** section.

The **BUILDPACKS** section displays the buildpacks for the app and all its components. Each buildpack shows its status (**Latest** or **Upgrade Available**) and provides a link to its documentation. If an upgrade is available, click **Upgrade to Version X**. Upgrading a buildpack redeploys your app.

### Upgrade All

To upgrade all buildpacks simultaneously, go to the [**Apps** page](https://cloud.digitalocean.com/apps) and select your app. If buildpack upgrades are available, the app’s **Overview** page displays a **BUILDPACK UPGRADES AVAILABLE** section. Click **Deploy Upgrades**. Upgrading buildpacks redeploys your app.
