Ecommerce Migration Services That Move The Store Without Losing Traffic
A replatform is a data project wearing a design project's clothes. Orders, customers, SKUs and every indexed URL have to arrive intact, on a date you chose, with a way back if they do not. Stallyons is a Delaware-registered US company, and we rehearse the move before we run it.

What Ecommerce Migration Services Really Cover
An ecommerce migration moves a live, trading store from one platform to another without breaking what it already earns. That is four jobs, not one: getting the data across without losing history, remodelling a catalogue that grew organically for years, mapping every indexed URL to its new address, and re-pointing the systems that quietly depend on the old store. The build is the visible part. The other three decide whether the move is survivable.
Stallyons is registered in Delaware as a US company, and our engineers work inside a time-zone window agreed before the project starts, with four-plus hours of daily overlap. You sign a US contract, run diligence on a US entity and pay one US invoice. Behind the work sits twelve-plus years of delivery across six continents and around thirty-five engineers, averaging four-plus years of production experience. Merchants, heads of ecommerce and CTOs across North America, the UK, Europe, the Middle East and Asia-Pacific bring us the move.
What An Ecommerce Move Covers
Data that arrives whole: products, variants, media, customers, addresses and the full order history, migrated with a reconciliation report you can read, so the counts on the new platform match the counts on the old one.
Search visibility carried across: every indexed URL mapped to a destination, 301s written before launch, canonicals, metadata and sitemaps rebuilt, so the equity you spent years earning does not reset on switch day.
A catalogue remodelled rather than copied: taxonomy, attributes and option sets redesigned for the new platform, because carrying fifteen years of accumulated mess across is how a fresh start stops feeling fresh.
Integrations re-pointed, not rediscovered: ERP, PIM, payments, tax, shipping, email and analytics all identified during the audit and reconnected in staging before anyone touches production.
A cutover you rehearse: the whole sequence run against a staging copy first, timed, written down and approved, so go-live is a checklist being followed rather than a decision being made.
A rollback that actually exists: snapshots taken, an abort point agreed in advance, and the old platform kept warm until the new one has proved itself against live orders and live crawlers.
Why Merchants Choose Our Ecommerce Migration Services
- Ask to see the URL map before contracting. If nobody has counted your indexed pages yet, nobody can tell you what the move will cost you in traffic.
- Ask what happens to order history. Plenty of migrations bring customers across but not their past orders, and support finds out the week after go-live.
- Get the rollback in writing: what triggers it, who calls it, how long the old platform stays available, and what state the data is in afterwards.
- Ask which integrations were found in the audit. The one nobody listed is usually the one finance depends on, and it surfaces at the first month-end after the switch.
- Check that the cutover is rehearsed, not just planned. A sequence that has been run against a staging copy has real timings; one that has not has estimates.
- Insist on post-launch monitoring being in scope. Crawl errors, broken redirects and failed orders show up in the first fortnight, not on handover day.
How An Ecommerce Migration Starts With Us
Every project starts with a free 45-minute assessment. No slide deck, no sales script. You bring the current platform, the catalogue and the constraints; you leave with a recommended migration path, a scope and a timeline.
We are selective about new projects and cap how many we run at once, because the audit is the product. If your current platform is worth keeping and fixing instead, we will say so on that first call.

Common Challenges
Why Do Replatforming Projects Fail?
Six patterns behind almost every migration that cost more than the quote. None of them are the new platform's fault.
Data Left Behind
01
Products and customers come across; order history, saved addresses, store credit and review content do not. Nobody notices until a customer asks for an invoice from last year and support has no answer.
Redirect Map Missing
02
The new URL structure is prettier and completely different. Thousands of indexed pages land on a 404, and the traffic chart explains it about three weeks later.
One Big-Bang Cutover
03
Everything switches on one evening with no rehearsal. The first time the sequence runs end to end is the time it has to work, on a store taking orders.
No Rollback Plan
04
Once the DNS has moved and orders are landing in the new system, going back means losing them. Without a snapshot and an agreed abort point, the only option is forward.
Integrations Forgotten
05
The ERP feed, the tax service and the warehouse export were never in the scope because nobody remembered them. Each one surfaces separately, as an emergency, after go-live.
Catalogue Copied As-Is
06
Fifteen years of duplicate attributes and dead options move across untouched. The new platform inherits the old mess, and merchandising is no easier.
Recognise the pattern? Let's plan the move.
Migration Services
Our Six Ecommerce Migration Services
Six ways to buy a platform move from one accountable vendor. Run one, or run several in parallel under a single contract.
End-To-End Platform Migration
01
The whole move end to end: audit, data mapping, catalogue remodelling, redirects, build, rehearsal and cutover, with a written plan you approve before anything is migrated.
Data Migration Only
02
Someone else is building the new store and you need the data moved properly: products, customers, orders and media, with mapping rules agreed and a reconciliation report at the end.
SEO Migration Planning
03
A full crawl of the current site, every URL mapped to a destination, 301 rules written and tested, and metadata and sitemaps rebuilt before launch.
Catalogue Restructuring
04
Taxonomy, attributes and option sets redesigned for the destination platform, so merchandising gets easier after the move instead of inheriting the old mess.
Integration Re-Pointing
05
ERP, PIM, payments, tax, shipping and analytics identified in the audit and reconnected against the new store in staging, then verified before cutover.
Post-Migration Monitoring
06
Crawl errors, redirect health, index coverage and order flow watched daily through the weeks that matter, with fixes shipped rather than added to a report.
Not sure which migration path fits? Let's scope it together.
Why Choose Us
What Makes Our Ecommerce Migration Services Different
The details that decide whether a replatform is remembered as a project or as an incident.
A US Legal Entity
01
Stallyons is registered in Delaware. Your contract, your invoice and your legal recourse sit with a US company, not an unknown one.
Nothing Lost In Transit
02
Every migration ends with a reconciliation report: counts, totals and spot checks on both platforms, so "it worked" is a number, not a feeling.
Overlap You Set
03
You choose the hours we share with your working day, and stand-ups, reviews and escalations all happen inside that window.
Rollback Always Ready
04
The abort point is agreed during scoping, snapshots are taken before the switch, and the old platform stays available until the new one has proved itself.
Reviewed Code
05
Every merge is reviewed against an agreed definition of done, on your board, where you can read it yourself.
One Contract
06
One contract covers the engagement, so procurement, legal and finance each deal with a single named counterparty.

Clutch Rating
"We came to Stallyons after burning two years and four vendors on a multi-platform launch that kept slipping. They scoped it end-to-end — web app, iOS, Android, an AI summarization layer, and a Shopify integration — and shipped it in 22 weeks. One team, one budget, one quality bar. We've handed them three more engagements since."

"Stallyons rebuilt our customer-facing portal, integrated three legacy systems, shipped an AI document analysis pipeline, and brought our compliance posture to SOC 2 — all under one engagement. The senior engineers on the team have shipped at companies five times our size. It's the best vendor decision we've made in a decade."

FAQ
Frequently Asked Ecommerce Migration Questions
Ecommerce migration services move a trading store from one platform to another without losing its data or its search visibility. The work covers auditing the current store, mapping products, customers and order history, remodelling the catalogue for the destination, writing redirects for every indexed URL, re-pointing integrations, rehearsing the cutover and monitoring afterwards.
In practice the words are used interchangeably, but they emphasise different halves of the same job. Migration describes moving the data: products, customers, orders and content arriving intact on the new system. Replatforming describes the decision to change platform at all, and everything that follows from it, including the catalogue redesign, the integration rework and the storefront build. A real project is always both.
Cost follows catalogue size, data quality and integration count, so anyone quoting a figure before the audit is guessing. What moves it most is how many indexed URLs need mapping, how much the catalogue has to be restructured, and how many systems talk to the current store. We audit first, then price it, and itemise what each phase covers.
It depends on the scope, and we put a timeline in writing before contracting rather than quoting a stock number. What changes the answer most is catalogue complexity, the number of integrations and how much cleanup the data needs first. We work in phases against milestones you sign off, and we schedule cutover away from your trading peaks.
Not if the mapping is done properly. We crawl the current site, map every indexed URL to a destination, write and test the 301 rules before launch, and rebuild canonicals, metadata and sitemaps. Some movement in the first weeks is normal while search engines recrawl, which is why we monitor daily.
Yes, and it is one of the routes we see most often. The awkward parts are usually the attribute model, customer groups and tier pricing, none of which map one to one. We agree those rules during the audit and show you the mapping before anything is moved, so nothing gets silently flattened on the way across.
It comes with you. Customers, addresses, order history, refunds and store credit are migrated with agreed mapping rules, then reconciled: counts and totals are compared on both platforms and spot-checked by hand. Anything the destination cannot represent natively is flagged in the audit, before you commit.
You go back. The abort point is agreed in advance, snapshots are taken before the switch, and the old platform stays available until the new one has handled live orders and live crawlers. Because the sequence is rehearsed against a staging copy first, most problems are found in the rehearsal rather than on the night.
