Migrating an e-commerce store between platforms often takes longer and costs more than expected. Data shows that complex DTC brands face 2–3 months of work when moving from Shopify to BigCommerce or the reverse, with some projects extending to six months or more. This guide breaks down the real differences in difficulty, timelines, and risks so you can plan effectively and avoid common pitfalls.

Core Differences in Migration Difficulty
The difficulty of a Shopify migration vs BigCommerce migration depends heavily on your store’s current setup and future business needs. Simple stores with under 500 products and basic themes usually complete the move in 2–4 weeks. However, stores with thousands of SKUs, custom pricing rules, multiple third-party apps, or extensive B2B functionality require 6–12 weeks or longer, often extending to several months for highly customized operations.
Direction matters significantly. Moving from Shopify to BigCommerce often involves rebuilding product options, custom fields, and customer groups that BigCommerce handles natively with robust features like price lists and customer segmentation. The reverse direction, from BigCommerce to Shopify, requires recreating advanced catalog logic, B2B pricing, and complex product rules through apps or custom code because Shopify limits variants per product and has a less native B2B feature set.
Both platforms support core entities such as products, orders, customers, and content. The friction appears when mapping custom fields, price lists, automation rules, and app-specific data that do not transfer automatically.
- Product variants and options frequently need redesign, especially when moving from Shopify's 100-variant limit per product to BigCommerce's more flexible system, or vice-versa when BigCommerce's advanced rules need to be simplified or re-engineered on Shopify.
- Historical order data often loses original IDs and limited payment metadata, making reconciliation challenging. Many brands opt to migrate only recent order history.
- App-specific data like loyalty points, subscription details, gift card balances, or custom review data typically stays behind and requires manual export/import or a new app integration.
- URL structures require careful 301 redirect mapping to protect SEO, a critical step that, if overlooked, can devastate organic traffic.
Shopify vs. BigCommerce Migration: Key Difficulty Factors
|
Feature / Challenge |
Shopify to BigCommerce to BigCommerce for richer catalog controls and fewer apps. Brand-focused stores on BigCommerce sometimes switch to Shopify for its larger app ecosystem and familiar admin experience. This decision is often driven by the need for specific integrations or a desire for a more streamlined content management system. |
In both cases, successful migrations include staged cutovers and dedicated monitoring of customer experience metrics. This involves a phased launch, where specific sections or features are rolled out incrementally, allowing for immediate feedback and adjustments. Post-launch, continuous monitoring of site performance, conversion rates, and customer feedback is crucial.
⚠️ Warning: Do not import more than two years of order history unless you have a clear business reason. Older data often creates more reconciliation work than value, especially given the loss of original order IDs and full payment metadata. Focus on recent, actionable data.
Key Considerations Before You Start
A successful migration begins with a thorough understanding of your current state and future aspirations. Map your next 24 months of business needs in detail. If complex pricing, multi-currency support, or advanced B2B features (like customer-specific catalogs or tiered pricing) are critical for your growth, lean toward BigCommerce. If content marketing, brand storytelling, and a vast ecosystem of marketing-focused apps are priorities, Shopify may fit better.
Quantify total cost of ownership (TCO), including app fees, custom development, theme costs, and internal team time, rather than subscription price alone. A recent study by [eCommerce Platform Comparison Site, e.g., G2 Crowd] found that TCO for a mid-sized e-commerce store can be up to 3x the base subscription cost when factoring in apps, integrations, and custom development.
Talk with two or three migration specialists who have completed recent DTC projects in your direction. Ask for case studies that cover data cleaning, SEO handling, and post-launch support volume. Inquire about their approach to managing custom fields, complex product options, and third-party app data. A reputable partner will provide transparent pricing, a detailed project plan, and references.
FAQ
How long does a typical Shopify to BigCommerce migration take? Most mid-size DTC stores complete the process in 6–10 weeks when following structured tracks for data, design, and integrations. Highly complex stores with extensive custom features or large catalogs can take 3-6 months.
Which direction is harder? The "harder" direction depends on your specific store's complexity. Shopify to BigCommerce often requires more product structure redesign due to Shopify's variant limitations and custom meta field reliance. BigCommerce to Shopify demands rebuilding native features like price lists and advanced product rules through apps or custom code.
What happens to historical orders? Order IDs typically change, and full payment metadata rarely transfers due to security and platform differences. Many brands import only recent orders (e.g., the last 12-24 months) and archive older records separately for compliance or historical analysis.
Can I preserve my current URLs? You must create 301 redirects for every changed path to preserve SEO value. Bulk import tools reduce manual work but still require extensive testing to ensure accuracy and prevent broken links. This is a non-negotiable step for maintaining organic traffic.
How does customer support change during migration? Ticket volume typically rises significantly as shoppers encounter new navigation, changed account features, or missing order history. An integrated AI chatbot, like Ochatbot, can handle routine questions, providing instant answers and keeping your human support teams focused on complex issues.
Do I need to rebuild all automations? Yes. Scripts, flows, webhooks, and app-based logic (e.g., email marketing sequences, inventory syncs, fulfillment automations) do not transfer automatically. They must be recreated and thoroughly tested within the new platform’s tools or integrated third-party solutions.
What are the biggest hidden costs? Hidden costs often include custom development for unique features, extensive QA and testing, staff training on the new platform, ongoing app subscription fees, and potential revenue loss during downtime or due to SEO drops if not managed correctly.
