<blockquote class="warning">

**Deprecated**

The Legacy Wix CLI for Apps is deprecated and no longer receives updates or new features. New projects should use the [Wix CLI for Apps](fallback::https://dev.wix.com/docs/wix-cli/cli-for-apps/about-the-wix-cli-for-apps).

- To find out which structure a project uses, see [Determine Which CLI Your Project Uses](fallback::https://dev.wix.com/docs/build-apps/develop-your-app/develop-an-app-with-the-cli/project-development/determine-which-cli-your-project-uses).
- To migrate an existing app to the new Wix CLI, see [Migrate a Legacy CLI App to the New Wix CLI](fallback::https://dev.wix.com/docs/build-apps/develop-your-app/develop-an-app-with-the-cli/migrate-an-app-to-the-new-cli/migrate-an-app-from-the-legacy-cli/migrate-a-legacy-cli-app-to-the-new-wix-cli).
