Drupal developer Matt Glaman has unveiled an exciting breakthrough in Drupal migration with his latest blog post, "Retrofit: Running legacy Drupal 7 code on your Drupal 10 site." As the impending end-of-life for Drupal 7 looms, Glaman addresses the challenges organizations face seeking to transition to newer versions of the platform.

The blog post sheds light on the arduous task of upgrading from Drupal 7, citing changes in defining elements such as routes, blocks, and user permissions, as well as the adoption of Symfony and Guzzle packages. While these changes are undoubtedly beneficial, they often require extensive code modifications, leading to a daunting migration process for development teams who must balance delivering new features with bug fixes.

To tackle this head-on, Glaman introduces Retrofit—an innovative solution that provides compatibility layers for running legacy Drupal 7 code on Drupal 10 sites.

Retrofit, available as a Composer package, can significantly simplify the migration process. Rather than rewriting extensive lines of code, developers can now copy and paste their Drupal 7 modules into Drupal 10, potentially reducing the refactoring effort from 98% to a mere 30%.

The concept of Retrofit represents a game-changing approach to Drupal migration, as it aims to bridge the gap between the old and new versions seamlessly. By implementing Retrofit, organizations can leverage their existing Drupal 7 codebase while benefiting from the advancements and improvements offered by Drupal 10.

Glaman's blog post serves as an introduction to Retrofit, highlighting its potential to revolutionize the migration experience. To delve deeper into the concept, Glaman encourages readers to watch an accompanying YouTube video that provides additional insights and demonstrations.

Although the November 1, 2023 deadline for Drupal 7's end-of-life has been extended as announced at the DrupalCon Pittsburgh, the danger still looms as many websites are running on Drupal 7. Now, Retrofit offers a lifeline for organizations seeking a smoother transition. Retrofit paves the way for more efficient Drupal migrations by mitigating the need for extensive code modifications, allowing businesses to maintain and evolve their websites effectively.

Drupal developers and stakeholders worldwide are eagerly anticipating the widespread adoption of Retrofit as a valuable tool in simplifying the challenging process of transitioning from Drupal 7 to Drupal 10. With its promise of reduced code modification and enhanced compatibility, Retrofit represents an exciting breakthrough in the Drupal community.
