# About Legacy CLIs

This section documents earlier project structures, for projects that still use them.

> **Note:** The content in this section applies only to these earlier structures. It doesn't apply to app projects that use the [current structure](fallback::https://dev.wix.com/docs/wix-cli/cli-for-apps/project-structure/about-the-app-project-structure).

## App projects

App projects have used three project structures over time. This section covers the two earlier ones:

- **Astro-based Wix CLI for Apps:** The earlier structure of app projects built with the Wix CLI, based on the Astro web framework. See [About the Astro-based Wix CLI for Apps](fallback::https://dev.wix.com/docs/wix-cli/legacy-clis/astro-based-wix-cli-for-apps/about-the-astro-based-wix-cli-for-apps).
- **Legacy Wix CLI for Apps:** An earlier CLI for app projects. You can no longer create projects with it. See [About the Legacy Wix CLI for Apps](fallback::https://dev.wix.com/docs/wix-cli/legacy-clis/legacy-wix-cli-for-apps/about-the-legacy-wix-cli-for-apps).

To find out which structure an app 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 move an app project to the current structure, see [About Migrating an 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/about-migrating-an-app-to-the-new-wix-cli).
