Step-by-Step Guide to Migrating Magento Luma to Hyvä Theme

by January 20, 2026

Magento store owners are increasingly switching from the default Luma theme to the Hyvä Magento theme for improved performance, modern frontend architecture, and enhanced user experience. Migrating to Hyvä can significantly boost page speed, Lighthouse scores, and maintainability, but it requires careful planning and execution.

“Migrating to Hyvä is more than a theme upgrade—it’s a transformation for faster, scalable, and future-ready Magento stores.”

This guide provides a step-by-step approach to Magento Hyvä migration, ensuring a smooth transition without disrupting your store operations.

Why Migrate from Luma to Hyvä?

The default Luma theme relies heavily on Knockout.js and legacy frontend structures, leading to:

  • Slower page loads

  • Larger CSS and JavaScript bundles

  • Lower Core Web Vitals and Lighthouse scores

Hyvä addresses these issues with:

  • Alpine.js for reactive, lightweight JS

  • Tailwind CSS for utility-first, minimal styling

  • Simplified frontend architecture for better performance and maintainability

Migration Benefits:

  • Faster page rendering and improved conversion rates

  • Cleaner, modern frontend code

  • Easier maintenance and future upgrades

Step 1: Plan Your Migration

Before starting, assess your current Luma theme:

  • List all customizations and third-party modules

  • Identify frontend dependencies

  • Backup the full store, including database and files

  • Test migration in a staging environment

Pro Tip: Document all Luma customizations to ensure critical features are ported correctly.

Step 2: Set Up a Development Environment

Create a safe development environment to implement Hyvä without affecting your live store:

  • Clone your store to a local or staging server

  • Install the latest Magento 2 version compatible with Hyvä

  • Ensure required PHP, MySQL, and server configurations meet Hyvä requirements

Step 3: Install Hyvä Theme

  • Purchase and download the official Hyvä theme

  • Install via Composer in your Magento project:

composer require hyva-themes/magento2-theme
php bin/magento setup:upgrade
php bin/magento cache:flush

  • Activate Hyvä in the Magento Admin Panel under Content > Design > Configuration

  • Assign the theme to your storefront

Step 4: Migrate Customizations

Hyvä uses a different frontend stack, so direct Luma customizations may not work:

  • Rewrite custom JS using Alpine.js

  • Convert CSS customizations to Tailwind utilities

  • Update templates and layouts for Hyvä’s simplified structure

  • Test each component to ensure functionality

Use Case: Product filters, modals, and custom blocks should be tested thoroughly for responsive behavior.

Step 5: Test Third-Party Modules

Not all Luma-compatible modules are Hyvä-ready. Steps include:

  • Check module documentation for Hyvä support

  • Test functionality in staging environment

  • Consider rewriting templates if required for Hyvä compatibility

Step 6: Performance Optimization

After migration, fine-tune performance for Hyvä:

  • Enable Varnish full-page caching

  • Configure Redis for cache and session storage

  • Optimize images and media for faster load times

  • Check Lighthouse scores and Core Web Vitals

Pro Tip: Hyvä naturally improves performance, but caching and server optimization maximize speed benefits.

Step 7: Go Live

  • Backup production store before deployment

  • Deploy Hyvä theme and customizations to production

  • Clear caches, reindex, and test all functionalities

  • Monitor user experience and performance metrics closely

Step 8: Post-Migration Best Practices

  • Monitor site speed, Lighthouse scores, and error logs

  • Train your team on managing the new Hyvä frontend

  • Plan for regular updates and maintenance to keep performance optimized

Conclusion

Migrating from Luma to Hyvä is a strategic move for Magento stores seeking faster performance, modern design, and maintainable frontend code. Following this step-by-step guide ensures a smooth transition, minimizes downtime, and leverages the full benefits of the Hyvä Magento theme.

“A successful Luma to Hyvä migration isn’t just a theme change—it’s a performance and user experience upgrade for your Magento store.”
