Where a BigCommerce migration can go wrong
The platform switch itself is rarely the hard part, but many projects fail on the things that only show up once real customer data and search traffic hit the new store.
Traffic drop at launch
Old category URLs return 404s because the redirect map was written after launch, and months of organic traffic go with them.
Incomplete data
Product and customer data ends up in a format BigCommerce cannot read, and your team spends weeks fixing it by hand.
Broken ERP connection
The new integration gets built without checking how the old one actually sent data, so orders go missing between store and ERP.
What a BigCommerce migration covers
Scope is agreed against your current store. A full replatform covers six areas, and each is estimated separately.
Catalog and data migration
We transfer products, variants, categories, customers and order history, then reconcile every record against the source platform.
Redirect and SEO mapping
Every indexed URL gets crawled and matched to a BigCommerce destination, with the whole map tested on staging before the DNS change.
Theme and storefront build
A BigCommerce theme built to your brand, using native platform features wherever they replace something custom you were maintaining.
ERP and back-office connections
Order and inventory flows to your ERP get rebuilt for BigCommerce, then operate in parallel with the old system until numbers reconcile.
Payments, shipping and tax
Gateways, carrier accounts and tax rules need reconfiguring for BigCommerce, and each is tested against real transactions on staging.
Launch and post-launch support
Going live is scheduled for a quiet window and stays reversible, with the team on hand through the first weeks while search engines recrawl.
Platforms we migrate to BigCommerce
Magento and Adobe Commerce
The most common source, and the one with the most data to untangle. scandiweb is the most certified Adobe Commerce agency in the world, so the audit starts from real knowledge of what you are leaving.
Shopify and Shopify Plus
Metafields, app-driven functionality and Liquid templates need translating into BigCommerce equivalents. Some apps have no counterpart and the workflow gets rebuilt, which we identify during the audit before the build starts.

WooCommerce and WordPress
Content and commerce usually need separating. Products migrate to BigCommerce while editorial pages are mapped, redirected and rebuilt so the blog equity you have earned keeps pointing somewhere valid.
Legacy and custom platforms
Older or in-house systems rarely have a clean export, so we work from the database directly, define the data contract, and reconcile the migrated records against the source before anything is signed off.
How a BigCommerce migration is delivered
Every migration follows the same four stages. The audit comes first because the quote depends on your current platform.
Audit the source platform
We crawl the live site, review the database, and list what migrates cleanly, what needs rebuilding, and what should be retired. The estimate follows from that list.
Build and map in parallel
The BigCommerce store is built while the redirect map is written against the crawl, so the two are finished together and can be tested as one thing.
Migrate, reconcile and test
Data is transferred to staging, reconciled against the source, and the integrations operate in parallel until order and inventory numbers match on both sides.
Go-live and monitor
Launch is scheduled for low traffic and stays reversible. We watch crawl errors, rankings, and order flow daily during the weeks that follow.

Frequently asked questions about BigCommerce migration
Will we lose organic traffic migrating to BigCommerce?
Not if the redirect map is built before launch. We crawl every indexed URL on your current store, match each to a BigCommerce destination and test the mapping on staging. Rankings usually dip for a few weeks while search engines recrawl, then recover. The permanent losses happen when redirects are written after go-live.
How long does a BigCommerce migration take?
Most projects need three to five months, driven by catalog size, how many integrations exist and how much custom functionality needs rebuilding as native BigCommerce features. The audit produces a dated plan before you commit, so the timeline is based on your actual store and not an industry average.
Will the store stay online during the migration?
Yes. The BigCommerce store is built and populated on staging while your current store keeps trading. The only interruption is the DNS switch at cutover, which we schedule for your lowest traffic window and keep reversible for the first days after launch.
Which platforms can you migrate to BigCommerce from?
Magento and Adobe Commerce, Shopify and Shopify Plus, WooCommerce, and legacy or in-house systems. Magento is the most common source and the most complex, because attribute sets and custom modules rarely map one to one. For systems with no clean export we work from the database directly.
What happens to our ERP and integrations?
They are rebuilt against BigCommerce and operate in parallel with the old system until order, inventory and customer numbers reconcile on both sides. Nature's One kept a Deacom ERP connection through middleware built during their replatform. Integrations are the most common cause of a delayed cutover, so they are scoped first.
Is scandiweb a certified BigCommerce partner?
Yes. Our developers hold BigCommerce certification and the firm appears in the official BigCommerce partner directory. We also hold Adobe Commerce and Hyvä platinum partnerships, which is what makes the audit of a Magento source store more useful than a destination-only view.
