Migrating from BigCommerce to Shopify Plus in 2 weeks

When Eartheasy wanted to migrate their store from BigCommerce to Shopify Plus, they had one non-negotiable: they didn’t want to lose momentum. Here’s how Saikai pulled it off in two weeks. 

Eartheasy offers solutions for sustainable living through eco-friendly products and educational content. To migrate their store content from BigCommerce to Shopify Plus, they partnered with Saikai, a Shopify web design and development agency. 

Saikai prefers using Figma as their primary design tool, so they wanted a tool that could bring their designs to life in Shopify. That’s why they used Instant for this project.

“We first started using Instant a year ago, one of our partners suggested it. Since then, it’s become our primary tool for quickly moving Figma designs into live Shopify stores.” — Konstantin Antonov, Founder & Creative Director at Saikai

Here’s how they migrated Eartheasy’s store design: 

Behind the build: Migrating Eartheasy to Shopify Plus

About Saikai 

Saikai is an official Instant Agency partner. The agency was founded by Konstantin Antonov, a specialized Shopify Plus expert. As creative director, he bridges the gap between technical precision and seamless design. He helps brands like Eartheasy to navigate projects like complex website migrations to new startup launches.

The project

This project for Eartheasy involved managing a complex transition: transferring a large catalog with hundreds of SKUs and SEO content from BigCommerce to Shopify Plus. 

“With so much data moving in the background, we needed a design solution that could keep pace and get the storefront live quickly. Instant allowed us to take our Figma sketches and build out the store's visual interface in a fraction of the time it would have taken to code from scratch.” 

Using Instant, they brought their designs from Figma, edited them, and then exported them to Shopify. 

Using this workflow, they built many key store elements, including:  

• Navigation: Mega menu & footer

• A reusable product page template

• Homepage theme sections 

• Store pages: About page, Team page, etc.

Here’s a look at what they built:

The Instant impact

The biggest impact Instant had on this project was eliminating bottlenecks and dramatically cutting build time, two things that matter a lot when a brand is eager to get its storefront live without disrupting sales or search rankings. 

“The biggest impact was the efficiency of the build phase. When you're dealing with a migration of this scale, the design implementation can often become a bottleneck. The ability to create and reuse our own custom sections was a key feature. It allowed us to transfer all of our design layouts and get the site ready in about 2 weeks. For a project involving such a large volume of content, having a tool that simplified the design-to-live process while preserving SEO was essential to meeting our deadline.”

The ability to reuse custom theme sections meant Saikai didn’t have to rebuild from scratch for every page. Instead, they could build once and apply broadly.

Preserving SEO performance was equally critical. Migrations of this size can risk disrupting rankings that have taken years to establish. Using Instant, Saikai could work fast, without cutting any corners that would hurt long-term search visibility. 

The final result

In just two weeks, Saikai delivered a fully functional, polished Shopify Plus storefront to Eartheasy. What could have taken months of custom development was condensed into a two-week sprint, thanks to Saikai’s smart design-to-deployment workflow. 

"Migrating a large catalog from any platform to Shopify is a massive undertaking that takes a lot of time to plan and execute. Instant allowed us to take our Figma designs and move from concept to a live, functional storefront in just 2 weeks, without compromising functionality.” — Konstantin Antonov, Founder & Creative Director at Saikai

For Saikai, Instant has become more than just a design tool. It’s an essential part of the workflow they’ve created that allows them to take on complex projects like this while still hitting aggressive deadlines. And for Eartheasy, it meant getting a brand-new Shopify Plus storefront without the wait.
