The storefront is the easy part. The data is where replatforms break.
We move B2B stores to and from Sana Commerce, BigCommerce, DynamicWeb, and Adobe Commerce (Magento). A studio building commerce since 2004, we have learned that a migration succeeds or fails on the customer master, the pricing rules, and the order history, not on how the new homepage looks.
Why B2B replatforms fail.
A B2C site can replatform on visuals and a checkout. A B2B store carries years of accumulated business logic, and that logic is what hurts when it is moved carelessly. Four risks cause most of the damage we get called in to fix.
Data quality
- The customer master is usually older and messier than anyone admits: duplicates, dead accounts, broken hierarchies.
- Migrating that as-is carries the mess forward and often surfaces it as visible bugs on the new store.
- We clean and reconcile first. See our note on customer master cleanup before a replatform.
Pricing logic
- B2B pricing is rarely a single list. It is customer groups, contracts, volume breaks, and regional terms layered together.
- If that logic is mapped loosely, a buyer can see the wrong price on day one, which erodes trust fast.
- We map pricing rules explicitly and test them against known historical orders before cutover.
SEO and redirects
- A new URL structure without a redirect map sheds rankings and breaks inbound links from buyers and partners.
- Indexed category, product, and content URLs all need a deliberate destination.
- We treat the redirect map as a deliverable, not a launch-day scramble.
Integration cutover
- The store rarely stands alone. ERP, tax, payment, shipping, and PIM systems all connect to it.
- A flip-the-switch cutover means every integration has to be perfect at the same moment, which is how outages happen.
- We sequence integrations and validate each one against real data before it carries live traffic.
How we replatform a B2B store.
The same sequence applies whether you are moving onto a platform or off one. Each phase exists to retire risk before it reaches your buyers.
Data audit and customer-master cleanup.
We profile the customer master, catalog, and order history first: duplicates, dead accounts, broken hierarchies, and gaps. This audit, not page count, is what sets the real timeline.
Pricing and catalog mapping.
We map customer groups, contracts, volume breaks, and regional terms onto the new platform, then validate them against known historical orders so prices match what buyers expect.
Parallel build.
We stand up the new platform alongside the old store rather than on top of it, so the live store keeps running while the replacement is built and proven.
SEO and redirect preservation.
We crawl the existing store, map every indexed URL to a 301 destination, and carry forward titles, descriptions, and structured data so rankings hold through the move.
Phased cutover.
We cut over in stages, often by customer segment or region, with the old store as a fallback. The blast radius of any problem stays small and reversible.
Post-launch hardening.
After traffic moves, we watch pricing, stock, checkout, and integration health, fix the edge cases real B2B traffic surfaces, and tune performance under genuine basket sizes.
To and from the platforms we actually build.
We are not tied to selling one destination. Because we build on several B2B platforms, we can recommend the move that fits your ERP, catalog, and buyers rather than the one we happen to resell.
Sana Commerce
- We move stores onto Sana Commerce Cloud when the ERP (SAP or Microsoft Dynamics) should be the live source of truth for pricing and stock.
- We also move off Sana when a business outgrows an ERP-first model and needs more storefront flexibility.
BigCommerce
- We move stores onto BigCommerce when storefront flexibility, a blended B2B and B2C model, or headless on Catalyst is the priority.
- We migrate from legacy carts where ERP data can flow through middleware rather than living inside the store.
DynamicWeb
- We build and migrate on DynamicWeb where content, commerce, and PIM benefit from living in one connected platform.
- We map its catalog and customer models carefully so the move preserves existing B2B pricing behavior.
Adobe Commerce (Magento)
- Aging or costly Magento builds are a common starting point for the replatforms we run.
- We extract the customer master, catalog, and order history cleanly, then map them to the destination without carrying the old debt forward.

Replatforming deliverables.
B2B replatforming, answered.
How long does a B2B replatform take?
It depends far more on data and integration complexity than on the storefront. A focused B2B store with a clean customer master and one ERP integration can move in a few months. A large catalog with messy customer records, layered pricing contracts, and several integrations can take longer. We scope after a data audit, because the audit is what tells us the real timeline rather than a guess based on page count.
Will we lose SEO rankings when we replatform?
You can hold rankings if redirects are treated as a first-class deliverable, not an afterthought. We crawl the live store, map every indexed URL to its new destination with 301 redirects, preserve titles, descriptions, and structured data, and keep canonical signals consistent. Rankings tend to slip when teams launch a new URL structure without a redirect map. That is the avoidable mistake we plan around from day one.
How do you handle customer and pricing data during a migration?
We treat the customer master and pricing rules as the highest-risk part of the project. We audit duplicates, dead accounts, and inconsistent hierarchies, then clean and map them before any build work. Pricing logic (customer groups, contracts, volume breaks, regional terms) is mapped explicitly to the new platform and tested against known orders, so a buyer sees the same price after cutover that they saw before. More on this in our note on customer master cleanup before a replatform.
Can you run the old and new store in parallel?
Yes, and we usually recommend it. We stand up the new platform alongside the old one and validate pricing, stock, and order flows against real data before sending any traffic. Cutover happens in phases, often by customer segment or region, so the old store keeps serving buyers until the new one is proven. If something is wrong, the blast radius is small and reversible.
