Drupal 7’s end-of-life (Jan 2025) has left many site owners looking for alternatives. One great option is Backdrop CMS, a Drupal 7 fork designed for small to mid-sized websites. It keeps Drupal 7’s best features while improving performance and ease of use.

If you’re considering migrating from Drupal 7 to Backdrop CMS, here’s a step-by-step guide to ensure a smooth transition.

Why Choose Backdrop CMS?

  • Same Familiar Structure: Built on Drupal 7’s architecture.
  • Lightweight & Faster: Improved performance with a smaller footprint.
  • Lower Maintenance Costs: No complex updates like Drupal 9/10.

Step 1: Backup Your Drupal 7 Site

Before migrating, make sure to backup your database, files, and themes to avoid data loss.

Step 2: Set Up a Backdrop CMS Environment

  • Download and install Backdrop CMS on a staging server.
  • Ensure PHP 7.3+ is installed.
  • Set up a new database.

*Step 3: Migrate Data from Drupal 7
*

  • Backdrop CMS has a built-in upgrade path:
  • Place your Drupal 7 database in your Backdrop site directory.
  • Modify settings.php to use the Drupal 7 database.
  • Run the Backdrop upgrade script (upgrade.php).
  • The system will migrate nodes, users, taxonomy, and menu items automatically.

Step 4: Rebuild Your Site

  • Backdrop CMS has a Layout system instead of Drupal 7’s block system, so you may need to:
  • Reconfigure Views (Backdrop has Views built-in).
  • Adjust Custom Modules (Some D7 modules are now part of the Backdrop core).
  • Test Content & Permissions to ensure everything works as expected.
    **
    Step 5: Test & Go Live**

  • Check for missing features.

  • Enable caching for better performance.

  • Once satisfied, switch your DNS settings and make your Backdrop site live.

Final Thoughts

Backdrop CMS is an excellent choice if you want a Drupal 7-like experience without complex migrations. It’s a cost-effective, long-term solution for small businesses, nonprofits, and organizations that don’t want to rebuild their sites entirely on Drupal 9/10.
