01 — THE CHALLENGE

Updating the Theme Without Breaking Customizations

The theme needed to be upgraded while keeping existing custom functionality and the storefront experience intact.

01

The Problem

Theme updates can introduce changes to Liquid templates, CSS, JavaScript, sections, and theme structure. Existing customizations therefore needed to be reviewed carefully.

The Solution

I reviewed the existing custom code, upgraded the theme, validated the affected areas, and performed regression testing before deployment.
