How to Migrate from Drupal 7 to Backdrop CMS

Are you still stuck with Drupal 7? Well, it is high to stop holding to the past and be a part of the future of CMS with Backdrop CMS.?

Drupal 7 does not provide security updates, and while it was a strong candidate for many years, the time has changed. Backdrop CMS is a platform that works like Drupal 7 while also delivering better flexibility, performance, and ease of use. If you are still stuck on migrating from Drupal 7 to Backdrop CMS, this guide will definitely help you with in-depth steps.?

Step By Step Guide On How To Migrate Your Websites

The steps to upgrade Drupal to Backdrop are the same process as upgrading from Drupal 6 to Drupal 7. In short, you have to delete the old code, drop the new one, and run the updated script.?

With any major upgrades, we suggest maintaining a second copy of your site to check it with the old version. We have outlined the process below.?

1. Ensure that a copy of your old Drupal 7 site is web-accessible.??(example: https://drupal-example.com )
2. Set up a new Backdrop codebase which is also web accessible. (Example: https://backdrop-example.com )
3. Download the contributed modules, layouts, and themes for your Backdrop site and place them in the right directories.?
4. Update the custom Drupal modules, and place the Backdrop versions in the modules directory for your backdrop site.?
5. Note: Almost 80% of the code in your custom Drupal modules should be compatible with Backdrop CMS. Key API differences include the configuration management system and the Layout system, while the other changes are minor.?
6. Copy the Drupal 7 files directory into your Backdrop codebase.
7. You can handle it in two different ways:

• Recommended way: Move the files from where Drupal default location to your preferred directory

a. Copy the files directory from Drupal 7 (normally Drupal/sites/default/files ) into the backdrop site (backdrop/files)

b. Make a default directory within backdrop/sites.

c. Make a symlink in your filesystem from sites/default/files to files.

d. After the upgrade, update the “Public file system path setting at admin/config/media/filesystem to files.?

• Alternative way: Place the files in the same location they were in Drupal.

a. Make a default directory within backdrop/sites.

b. Copy the files directory from Drupal 7 (drupal/sites/default/files) into the Backdrop site (backdrop/sites/default/files)

8. Restore the Drupal 7 database backup (backdrop-ready.sql) into the database set up in step

9. Update the Backdrop setting and php file according to step 2 from the installing Backdrop page.

• Connect the new Backdrop site to the old Drupal 7 database.
• Check and also update where configuration files should be stored.
• Set $update_free_access to TRUE.
• Specify the Layout Template to use for block placement at the time of upgrade.?
• DO NOT run the installer. The next step will be to create the required configuration files and update the database.?

10. Open up a browser and visit https://backdrop-example.com/core/update.php to move forward with the update ( change example.com here with the local site or domain alias.

• Note: You are required to be both logged in and have sufficient privileges to run the update. If this is not the case, you can always modify it $settings['update_free_access'] = TRUE; in your setting.php file.?
• Note: until after the update has been run, your site will not function normally. Hence, we recommend you run the update script before visiting any other page on your site.?

11. You will get over 100 pending updates but do not worry. In most cases, it will only take a few seconds to complete.?

12. Once it is completed, click around your Backdrop site to confirm everything is working as expected.?

Final Step: Verify and Test Everything

After successfully migrating from the Drupal 7 site to Backdrop CMS, there are just a few steps that you need to follow.?

1. Ensure that the theme you chose is properly enabled. In case you are using a different theme in Backdrop than you did in Drupal, you should be able to enable the new theme now.?
2. Check layouts and blocks.?

3. Check views?

• Check your views again. Although Backdrop will make an effort to improve your views, some D7 view components, which may appear to have broken or missing handlers and require updating, do not have corresponding equivalents in Backdrop.

4. Check contrib projects?

• Technically, all the control projects should contain upgrade paths from Drupal 7 to Backdrop. However, your site may have a use case that is yet to be thoroughly tested. Test everything and report any problems in the right issue queue.?

Final Thoughts

Migrating to Backdrop CMS from Drupal 7 is a wise decision for those who want to maintain a contemporary, safe, and user-friendly website without any challenging learning curve. All of Drupal 7's functionality is available with Backdrop, but it's easier to manage and performs better.
