> Learn how to sync content from a production account to a CMS Developer Sandbox account.

> [accordion] Supported products

Sync content from a production account to a CMS Developer Sandbox account to keep assets in your sandbox environment up to date.

This one-way sync supports a variety of content-related data, from templates and modules, to brand settings and navigation menus, so that you can ensure you're accurately testing and iterating.

## Content types

You can sync the following types of content from your production account to a CMS Developer Sandbox account:

* **Developer assets:**
  * **Themes:** theme files and settings, theme field configurations, and theme CSS and JavaScript.
  * **Templates:** page, blog, email, and system templates.
  * **Modules:** custom modules, module configurations, and module assets (HTML, CSS, and JavaScript).
  * **Global Partials:** header and footer template partials, reusable template sections, and global partial configurations.
* **Content supported assets:**
  * **Developer assets:** all developer assets above.
  * **Website/Landing page content:** images, documents, content embeds, and files used on your pages (including videos and downloadable content).
  * **Navigation menus:** primary and secondary navigation menus, and footer menus.
  * **Brand settings:** colors, fonts, and logos, along with global style settings.
  * **GraphQL-enabled HubDB tables & data:** custom database tables and dynamic content collections.
  * **Global content:** headers and footers, along with global settings and partials.

> [!NOTE]
>
> CMS assets built using developer projects are not supported by the content sync tool.
>
> * If you're syncing content assets (e.g., pages) that use project-built developer assets, such as React modules, you should manually upload the project to the CMS Developer Sandbox account.
> * After uploading a CMS React project to the account, you may need to update references to those developer assets, as their IDs will have changed due to being uploaded as a new project.
