Process involved in Big Commerce to Shopify Migration project

Planning and Organizing

First we understand the business objective of the client and then document all the key requirements and identify the key bottle-neck areas in the project. Based on our experience we establish a plan that ensures a smooth migration process and simplify the overall process and shorten the project timeline.

Theme Selection

We use out of box Shopify template that reflects the branded eCommerce experience. We even check for device compatibility. Based on the performance of your store in terms of conversion rates, trust-worthiness and more we customize a mobile-friendly theme for the new Shopify store. We ensure that the organization brand image through the website gets a boost.

Prepare The SEO Plans

As a part of the migration, we ensure SEO juice is retained including URLs, meta tags, meta titles, page titles, etc. For that, we compile a list of all the URLs and then post-migration we check all those URLs are retained and check for any broken URLs and pages. We make sure all the relevant pages are accessible to the search engines.

Data Migration

Actual migration of all the contents including the products, customer details, order details, categories, images, blogs, coupon codes, reviews, etc. are migrated to the new store. This step also involves the refactoring code third party extensions. We ensure that the entire content of the old store is migrated to the new store.

Reviews And Cleanup

Nothing gets delivered to our customers without performing testing at user acceptance and integration levels. This step of migration includes thorough testing of third party API and payment gateway integrations. Test orders are placed and end-to-end workflows are mocked for real-time testing.


After the development and testing activities cease, a final content validation is performed and voila! The final website is ready to go live over the internet.

Success Story

I’m the owner of Forester Beauty in Switzerland and we have been running a webshop under Magento, which was just not up to date anymore. I’ve contacted Dee and he led me through the whole process of migrating our online shop to Shopify, including custom elements to enhance user experience. The whole Project Team at Cartunited has a very professional attitude and provide their support and insights promptly. They go above and beyond to satisfy their customers needs and assisted me even during their off working hours and weekends.

The Result was great, we now have a state of the art onlineshop and did not have any downtime for our customers, sales have been up by 10% in the first month already and we aim to have it a 25% by mid year. I can only recommend to work with Cartunited as they only work with experts in their field and that helps us as clients in the end as they seem to be able to tackle every problem you can think of.
