Shopify Plus Migration & Customization for ShopMelissa
Project Overview
ShopMelissa had become a well-known fashion brand, but their success was creating a critical problem. Their eCommerce platform was failing them. The site, built on BigCommerce, couldn’t deliver the premium customer experience needed to compete, and its slow performance was hurting sales. Additionally, significant backend inefficiency was wasting their team's valuable time. They recognized the need for a complete migration to a stronger platform, guided by a Shopify Plus expert, to overcome their growth ceiling and ensure their future.
Challenges
While ShopMelissa was a successful and growing brand, their underlying technology on BigCommerce was creating significant roadblocks that actively prevented them from reaching their full potential. The platform's limitations were causing a cascade of issues that affected everything from customer experience and brand perception to internal team morale and operational efficiency. It became clear that to continue scaling, they needed to overcome these critical technical hurdles that were holding the business back.
- Data Integrity: Ensuring perfect data integrity was the top priority. The transfer carried a big risk of losing years of important order histories and customer account data. Losing this data would have seriously damaged long-term relationships and customer trust.
- SEO Preservation: One of their main goals was to maintain their high search engine rankings. They had invested a lot in SEO and content. A poor migration without a careful 301 redirect plan would have resulted in disastrous 404 errors and could have caused a drop in their hard-earned organic traffic.
- Scalability & Performance: Slow performance from the old site's outdated structure frustrated users and led to higher cart abandonment rates. This issue was especially significant during busy sales periods like Black Friday when the platform struggled to handle the growing traffic.
- Backend Inefficiency: Their internal team was wasting many hours dealing with a slow and complicated backend. The brand struggled to stay agile because simple tasks, like launching a new collection or updating product information, took too long and were overly complex.
- Complex Product Catalog: They managed a large and complicated product catalog filled with many variations, categories, and images. To avoid broken product pages, wrong inventory levels, and a poor customer experience after launch, the entire catalog needed to be transferred with complete accuracy.
- Social Proof Migration: For a fashion brand where consumer approval matters, keeping social proof was essential. This meant successfully transferring thousands of valuable product reviews from their old system to Judge.me on Shopify to maintain customer trust and conversion rates.
Objective
The core objective was to architect a complete digital transformation for ShopMelissa by executing a strategic e-commerce platform migration to Shopify Plus. This wasn't just a technical update; it was a foundational business move designed to achieve three critical goals:
- Unlock Scalability & Performance: Build a high-performance storefront capable of handling massive traffic spikes during sales events and supporting long-term growth without compromising speed or reliability.
- Elevate the Customer Experience: Deliver a premium, mobile-first shopping journey that reflected the quality of the ShopMelissa brand. This included achieving sub-2-second page load times and creating a seamless, intuitive checkout process to reduce cart abandonment.
- Drive Operational Efficiency: Empower the ShopMelissa team by replacing their cumbersome backend with Shopify's streamlined interface. The goal was to reduce time spent on manual tasks, allowing them to manage their complex product catalog with ease and focus on growing the business.
My Role & Responsibilities
My role was comprehensive for this detailed project. As the main technical specialist, I oversaw each key phase of development and migration to ensure a successful outcome.

- SEO Strategist: To protect their organic traffic and ensure a smooth transition for search engines without lowering their rankings, I created and put into action a complete 301 redirect map.
- Integration Expert: To keep the valuable social proof from thousands of product reviews, I managed the seamless integration of all necessary third-party apps, including the migration.
- QA & Launch Lead: Finally, I was responsible for conducting thorough testing on multiple devices to ensure that the new Shopify Plus store launched smoothly and without any bugs.
Process
My proven six-step process ensured this complex migration was handled with precision, eliminating risks and ensuring a seamless transition from BigCommerce to Shopify Plus.
- Discovery & Strategic Planning: I began by thoroughly reviewing their current BigCommerce store. I examined its technical setup, data structures, and app dependencies. This discovery phase was crucial for creating a detailed project roadmap and a consistent timeline for the entire migration.
- Data & SEO Migration:I began by thoroughly reviewing their current BigCommerce store. I examined its technical setup, data structures, and app dependencies. This discovery phase was crucial for creating a detailed project roadmap and a consistent timeline for the entire migration.
- Custom Theme Development: The main focus of this important stage was the safe transfer of all customer accounts, order histories, and the detailed product catalog. To maintain their search rankings, I carefully mapped each old URL to a new one using 301 redirects and implemented an SEO preservation strategy.
- App Integration & Configuration: I built a unique Shopify theme from scratch, using their Figma designs as a reference. I focused on quick performance, developing the entire theme with a mobile-first approach and clear, lightweight code.
- Rigorous QA Testing: I set up and installed their core apps, with a focus on the Judge.me integration. To ensure that all thousands of existing product reviews were transferred and displayed correctly, I followed a detailed and careful process.
- Flawless Launch & Handover: In a staging environment, I conducted a rigorous QA testing process for the new Shopify Plus store. I tested all integrations, simulated user journeys, and confirmed functionality across popular browsers and mobile devices to ensure a smooth experience.
Solutions Implemented
I developed a multifaceted solution that addressed ShopMelissa's issues by focusing on three main areas: strategic integrations, custom front-end development, and a solid platform migration.
- Platform Migration to Shopify Plus: A well-planned migration from BigCommerce to Shopify Plus served as the key fix. I chose Shopify Plus for its excellent scalability, enterprise-level features, and user-friendly backend. This change directly solved problems with performance and backend inefficiency. It provided their team with a stable platform that could handle busy sales events and simplify daily tasks.
- Custom "Figma to Shopify" Theme Development: I created a completely unique theme using their expert Figma designs to tackle the issue of a generic look and strengthen the brand. This solution produced a distinctive, mobile-first, pixel-perfect storefront that accurately represented their luxury fashion brand. The slow performance of their old website was resolved by the custom-coded theme, built with simple, lightweight code.
- Strategic App & Data Integration: I implemented important integrations to protect their valuable assets and improve functionality. The most crucial was the Judge.me integration, which addressed the "social proof" issue by requiring a specific process to safely transfer thousands of product reviews. I also put in place a detailed 301 redirect map as part of the SEO preservation strategy. This was a direct response to the risk of losing organic traffic.
Outcomes
The move to Shopify Plus was a clear success. It changed ShopMelissa's operations and set them up for future growth. The project removed all main challenges from their old platform. This resulted in a fast, scalable, and easy-to-manage eCommerce system that allowed the team to focus on development. Most importantly, the entire transformation maintained 100% data integrity and did not harm their valuable SEO traffic. This ensured the business could continue to thrive without any interruptions.
