Migrate to the New Version

After installing a new DevExtreme version, update your projects using the instructions in this article.

NOTE
You should uninstall a newer version before downgrading to a previous version.

Upgrade DevExtreme Sources

Depending on how your app receives DevExtreme sources, do the following:

Local Files

Replace older DevExtreme files with the latest version. You can find the new files in the DevExtreme zip archive or DevExtreme folder (C:\Program Files (x86)\DevExpress 18.1\DevExtreme\Sources\Lib by default).

If you customized the old CSS files, you should make the same changes to the new CSS files and only then use them as a replacement.

CDN Services

Replace the version in CDN links. Relevant links are listed in the CDN Services article.

npm Packages

Run the following commands:

npm install devextreme@18.1 --save --save-exact
npm install devextreme-angular@18.1 --save --save-exact // If you use DevExtreme with Angular

ASP.NET MVC Controls Sources

Follow the instructions from the Add or Upgrade the Resources in an Existing Project article.

Upgrade Themes Created in Theme Builder

Follow the steps below to upgrade a theme created in the Theme Builder if you saved the theme's metadata:

  1. Open the Theme Builder.

  2. Click Import and select Import metadata from the drop-down menu.

  4. A warning is displayed that notifies you that the metadata's version does not match the Theme Builder's version. Different versions can cause issues if the Less variables used in the metadata were renamed or removed. Click Yes to continue applying the metadata.

  5. Check that the metadata is applied, perform additional customizations if required, and save the upgraded theme.

Learn What's New

See What's New in v18.1 to learn about the new features, or browse the DevExtreme version history for details on which features any major or minor release implemented and the issues they resolved.

Learn Breaking Changes and Deprecated API

We always do our best to minimize the impact an upgrade has on existing projects. However, it is often necessary to change our tools' UI, API, or behavior to improve them. Take the following into account to ensure that your app works after upgrading:

  • Breaking Changes
    Refer to the breaking changes introduced in v18.1. Follow the instructions given for each change to mitigate its possible impact.

  • Deprecated API
    We recommend replacing depreciated APIs with their relevant counterparts because they can break your app once they are removed. Run the upgraded app and open the browser's console. A notification suggesting replacements is displayed if your code uses a deprecated API. Update your code to use the replacements instead of the deprecated API.

You can submit a ticket to our Support Center if you experience any problems migrating to the new DevExtreme version.
