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 logs, 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.
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.
