How to Update a Theme on Shopify

Updating your Shopify theme ensures you have the latest features, design improvements, and bug fixes. Here’s a step-by-step guide on how to update your theme, while keeping your customizations safe.

1. Check If an Update Is Available

• Go to your Shopify admin.

• Navigate to Online Store > Themes.

• If an update is available for your theme (from the Shopify Theme Store), you’ll see a notification or an option to update.

2. Back Up Your Current Theme

Before making any changes, always back up your existing theme:

• In the Themes section, click Actions > Duplicate to create a copy of your current theme.

• Optionally, download the theme file for extra safety.

3. Add the Updated Theme Version

• Click the update notification or Add to theme library. This will add the new version to your theme library without affecting your live site.

• The new theme will be labeled as Updated copy of [Theme Name].

4. Review and Transfer Customizations

• Theme Editor Changes: Most customizations made using the theme editor (settings, sections, templates, app embeds) are automatically copied to the new version.

• Custom Code Changes: Manual code edits (in the code editor) are not transferred automatically. You’ll need to manually move these changes:

  • Use a code comparison tool (diff checker) to identify changes between your old and new theme files.

  • Copy over necessary code customizations, such as those in Liquid, CSS, or JavaScript files.

  • For settings, copy the contents of settings_data.json from your old theme’s Config folder to the new one if needed.

5. Test the Updated Theme

• Preview the new theme in your theme library.

• Check all customizations, app integrations, and storefront functionality to ensure everything works as expected.

6. Publish the Updated Theme

• Once you’re satisfied, click Actions > Publish on the new theme to make it live.

Additional Tips

• Third-Party Themes: If your theme was purchased outside the Shopify Theme Store, updates may not be available through the admin. You may need to manually install a new version and migrate your settings and customizations.

• Theme Updater Apps: Some developers offer apps (like “Theme Updater” by Out of the Sandbox) to automate the update process and help transfer settings.

• Compatibility: Some apps or customizations may not work with the new theme version. Test thoroughly before publishing.
