# Upgrade JSS 22.8 Next.js apps to version 22.9

This topic covers most of the changes you must make to your existing JSS 22.8 applications to take advantage of the new features in version 22.9. However, because of the nature of JavaScript and Next.js application development, this topic doesn't account for all the customization you might have in your existing application.

While upgrading, consider the JSS templates and add-ons you used when creating your Next.js application. You can find them in your `package.json` file. For example, a JSS 22.8 application might use the following templates and add-ons:

- `nextjs`
- `nextjs-styleguide OR nextjs-sxa`
- `nextjs-multisite`

> [!note]
> **Before you begin**
> -   If you haven't already done so, [upgrade your app to JSS 22.8](https://doc.sitecore.com/xp/en/developers/hd/22/sitecore-headless-development/upgrade-jss-22-7-next-js-apps-to-version-22-8.html "Upgrade JSS 22.7 Next.js apps to version 22.8").

> -   Familiarize yourself with the [changelog](https://github.com/Sitecore/jss/blob/6161999333adeef862eb5b84d1e1045b84df35b6/CHANGELOG.md#2290). If your application is heavily customized, the changelog can provide guidance on what additional changes you need that are not covered in this topic.

## Update application dependencies in your existing app

For your upgraded application to work correctly, you will need to update dependencies.

To update your dependencies:

1. In your existing application's `package.json` file:
    - Update every `@sitecore-jss` package to version `~22.9.0`.
    - Update the following dependencies to the specified versions:

        ```json
        "next": "^15.4.6",
        "sharp": "0.34.3",
        ....
        "chokidar": "~4.0.3",
        "cross-env": "~10.0.0",
        "@types/react": "^19.1.7",
        "@types/react-dom": "^19.1.7",
        ...
        ```

2. Install the dependencies with the following command:

    ```shell
    npm install
    ```

## Next steps
