Key Takeaways

»Complex catalogs and B2B pricing strain BigCommerce at scale, and ERP and PIM connections add pressure.
»Adobe Commerce handles B2B pricing, approval workflows, and multi-store management natively.
»Your data migrates over, but the storefront, apps, and checkout need rebuilding.
»Four steps carry the project: catalog, integrations, data validation, and SEO redirects.
»Waiting makes the project bigger, so an early start gives you room to plan.

BigCommerce is an excellent solution for growing brands, offering a strong starting point for early-stage and mid-market businesses building their online presence. However, when SKUs increase, when pricing rules get more advanced across segments, and when the need for ERP and PIM integrations increases, BigCommerce becomes more of a constraint. This is when many brands start thinking about eCommerce replatforming.

If your store has a deep catalog and customer-specific B2B pricing, a BigCommerce to Adobe Commerce (Magento) migration is usually the right move. Adobe Commerce handles this complexity natively, so you don’t have to spend time on fixes.

Signs You've Outgrown BigCommerce

A few patterns show up before a BigCommerce to Adobe Commerce (Magento) migration decision gets made.

Catalog workarounds become routine: BigCommerce's data model struggles with highly configurable products and deep attribute sets.

Dev requests keep hitting native limits: BigCommerce works well with its built-in features. When an idea falls outside them, developers have to build a workaround, and those may slow every request that follows.

Multi-store operations get expensive: Running separate storefronts for different markets, each with its own pricing and localization logic, drains resources inside a rigid system.

ERP and PIM integrations keep breaking: When ERP and PIM connections keep failing, the cause usually sits in the architecture under the storefront, so patching the integration only treats the symptom.

BigCommerce's B2B Edition hits a ceiling: Customer-specific pricing, approval chains, and account-based purchasing are core B2B eCommerce requirements. BigCommerce's B2B Edition covers the basics, but complex versions of these workflows often require paid third-party apps to function.

Growth keeps adding work: When scaling the business means stacking more workarounds, the platform and the business are no longer aligned.

Why Adobe Commerce (Magento) Fits the Next Stage

Scaling brands want every client to have a great experience, and those selling B2B feel that pressure most. A large buyer logs in expecting to see their own negotiated pricing and to send an order through their company’s approval process.

Your website should handle that smoothly, from the first click.

Adobe Commerce (Magento) makes that possible. Customer-specific pricing and approval workflows are native, so buyers get the right prices and the right process from day one. Your team can customize down to backend workflows, and a new market gets set up inside one centralized system, with no duplicate store to maintain. Large, highly configurable catalogs also stay manageable without the structural ceilings that show up on SaaS platforms.

Even if B2B is only part of your sales today, it tends to grow with the business. Choosing a platform that already supports it means you won’t need another migration to get there.

Which Parts of Your Store Move to Adobe Commerce (Magento)

When migrating from BigCommerce to Adobe Commerce (Magento), your data moves across with careful mapping. The storefront and the apps behind it are rebuilt on the new platform.

Transfers with mapping

Products and SKUs, including pricing and inventory
Customer records and order history (usually a recent window)
Categories and catalog structure
SEO metadata, where mapped correctly

Gets rebuilt

Storefront theme and design (BigCommerce themes can’t be carried over)
Apps and app-based logic (each needs a native Adobe Commerce (Magento) feature or a custom-built equivalent)
Checkout and payment configuration, along with tax rules
Customer passwords (hashed differently between platforms, so customers typically reset them on first login)

BigCommerce to Adobe Commerce (Magento) Migration Process

BigCommerce to Adobe Commerce migration tends to run in four steps, and each one shapes the next.

1. Update your catalogs according to your new site structure

How products are modeled in BigCommerce and Adobe Commerce (Magento) is fairly different. For variants and configurable options, Adobe Commerce (Magento) uses a flexible system, thus, attribute sets and categories need to be mapped and restructured.

2. Integrate ERP and PIM

At this point in the migration, many stores connect their ERP or PIM (or both). These integrations are rarely done as-is. Codilar audits them and builds them again according to the Adobe Commerce (Magento) API.

3. Migrate and validate data

After the API is built and integrated, the next step is to migrate the data. Validations are then run to check if the data import was done correctly.

4. Add SEO mapping and migration

URL structures are different on the two platforms. Every live URL must be mapped to its new location on Adobe Commerce (Magento) and a 301 redirect implemented to ensure SEO is not broken.

Migration Timeline

Timelines depend mostly on catalog size and integration complexity.

Small catalog, simple logic: roughly 6 to 8 weeks
Mid-sized brand: roughly 8 to 12 weeks
Enterprise or B2B: roughly 12 to 20+ weeks

Mapping your existing integrations and data structures before development starts sets a realistic schedule early and keeps the project on track through go-live.

Why Waiting Too Long Costs More

When you don’t switch to a better solution that matches your needs when available, you’ll continue to accumulate issues that become harder to address. Custom integrations for ERP quickly break, and B2B buyers who want personalized pricing are left unfulfilled. A more flexible competitor may win that order.

The migration also gets bigger the longer you wait. More data and more custom logic mean more to map and test, which stretches the timeline above. Starting early gives you room to plan. You can clean up old data and pick a launch date outside your peak season.

Every fix you add now is one more thing to rebuild later. Contact Codilar today to discuss your migration and get pricing details for your store.

FAQs

Brands migrate when they need deeper catalog customization and native B2B features than BigCommerce’s plan-based model can support.

Roughly 6 to 8 weeks for a small catalog, 8 to 12 weeks for a mid-sized brand, and 12 to 20+ weeks for enterprise or B2B stores. Catalog size and integration complexity drive most of the difference.

Rankings are at risk mainly when the redirect map is incomplete. Mapping every live URL to a 301 redirect and carrying over page titles and meta descriptions helps protect them.

Your catalog and customer data move across with careful mapping, along with a recent window of order history and your SEO metadata. The storefront and apps are rebuilt on Adobe Commerce, and so are checkout and payment setup.

In most cases, yes. The two platforms model data differently, so catalog structure, integrations, and redirects all need an experienced hand. Errors in any of them tend to surface after launch, when they cost more to fix.
