Source and target data audit
Record counts, custom fields, and data quality problems found in your old and new platforms first.
The Problem
One Rushed Import Can Cost You Orders, Data, and Rankings
It shows up on the switch weekend, when data, integrations, and DNS all change at once and nobody owns the order of events.
01 · Store downtime
The store can't go dark while 40,000 orders move.
A planned cutover keeps you selling while systems change hands.
02 · Integrations
Your ERP expects its own order format.
ERP, 3PL, tax, and email tools switch over in the same window.
03 · Rushed imports
A one-shot Friday import can cost a weekend of orders.
A full dry run gets reconciled record by record before the real move.
04 · Marketing timing
An email campaign goes out Monday, mid-move.
A written runbook sets freeze times, DNS changes, and rollback points.
Your new platform is signed. Now someone has to move 40,000 orders, 12,000 customers, and 800 active subscriptions without the store going dark. Your ERP expects orders in one format, and your payment gateway holds the saved cards. Marketing has an email going out Monday. A one-shot import on Friday night is how stores lose a weekend, and sometimes their customers.
We run the move as a managed project. First comes a full dry run into the new platform, reconciled record by record. Then a planned cutover: a catalog freeze, a final import of orders placed since that rehearsal, DNS switched in a quiet hour, and integrations pointed at the new store. You keep selling while systems change hands, instead of posting a back-soon page.
A rehearsal first
Every record moves once in a test pass, so the live migration repeats a proven process.
A written cutover runbook
Freeze times, delta imports, DNS changes, and rollback points, each with an owner and a time.
Integrations switched together
ERP, 3PL, tax, and email tools move to the new store in the same window as the data.
Our Migration Process
From Scoping Call to Cutover in Five Clear Steps
You approve the data map and the cutover runbook before the rehearsal, then review its results before anything goes live.
We review your current and target platforms, data volumes, subscriptions, and every connected system. You get a list of risks and a cutover approach. If a self-serve migration tool fits your data, we'll tell you before we quote.
What's Included
What You Get With Our Ecommerce Data Migration Services

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built and relaunched ecommerce stores for.
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture
Why Store Owners Trust Us With Their Platform Switch
Switching platforms puts data, payments, and integrations in motion at once. These habits come with our ecommerce platform and data migration services.
Dry run before the real run
Every migration starts with a full rehearsal into the new platform. You review real records there, so the live move holds no first attempts.
Runbooks, not guesswork
Cutover steps are written down with owners, times, and rollback points. Everyone knows what happens in the launch hour, including you.
Saved cards stay with processors
Your subscribers' saved cards move between payment providers through token migration. Card numbers stay with them, so renewals keep running without re-entered details.
Every system gets a first order
Before cutover, each connected system receives a test order from the new platform. Your warehouse and accounting see the switch before customers do.
Straight advice on platforms
We recommend a target platform from your data and costs, not our preferences. If staying put is cheaper, we'll say so.
You own the data map
The data map, scripts, and reconciliation reports are yours at handover. Your team can audit or rerun the migration without us.
Overview

Good fit
Stores leaving Magento for BigCommerce
Your team chose BigCommerce, and you need Magento data moved by someone who isn't also selling you a platform.
WooCommerce stores with subscriptions
Your WooCommerce store bills hundreds of subscribers every month, and renewals can't stop while you switch platforms.
Brands with ERP and 3PL links
Your orders flow to an ERP and a 3PL, and both need to pick up the new store's orders on day one.
Teams comparing managed options
You're comparing ecommerce store migration services and want one team accountable for data, integrations, and launch.
Agencies with a platform switch
Your agency is moving a client to Shopify, and you need the data and cutover handled while you run the design.
Not a fit
Common move to Shopify
You're moving to Shopify from one common platform. Our Shopify migration hub, linked below, and its platform pages have set prices for that move.
Platform not chosen yet
You haven't decided whether to switch platforms at all. Our Ecommerce Replatforming Services page starts with that decision.
Rankings only
You only need rankings protected while another team moves your data. Our SEO Migration Services page covers that layer on its own.
Under 100 products
Your budget is under $700, or your store has fewer than 100 products. A self-serve migration tool and a CSV import will do the job.

Your migration costs $700, $2,600, or $6,200 with us, depending on your data volume, integrations, and how many systems feed your new store. The $700 plan moves data into a store your team has built. The $2,600 plan runs the full platform move with cutover. The $6,200 plan merges several sources and rebuilds more integrations.
Most platform moves take 2 to 12 weeks. A data-only move into a finished store takes about 2 weeks. Full moves with integrations take 4 to 8 weeks, and multi-system merges run toward 12. The rehearsal and your review of it take the most time.
Our ecommerce platform migration services cover moves between Shopify, BigCommerce, WooCommerce, and Magento, in either direction. If you're moving to Shopify, those moves have their own pages with set prices. For other pairs, we check both platforms' limits during scoping, such as Shopify's 3 options per product.
Your data moves in dependency order, and every batch is reconciled against the source. Products load first, then customers, then orders linked to them, then subscriptions with their billing dates. Saved cards move through your payment provider's token migration, so raw card numbers stay with the providers. Passwords don't transfer between platforms, so customers set a new one or use a one-time code where offered.
We avoid downtime by keeping your old store live until your new one holds every record and has passed its checks. At cutover we freeze catalog edits, import orders placed since the rehearsal, and switch DNS in your slowest hour. Orders that land on the old store while DNS updates get imported afterward.
We protect your SEO by redirecting every old URL to its closest new page with a 301 and carrying titles, descriptions, and canonical tags across. Google warns against pointing many old URLs at the home page, so each redirect gets a real match. Each redirect is then checked with a crawl before your domain moves.
Our plan has five stages: scoping, data map and runbook, dry run, integrations, and cutover with 30 days of monitoring. The runbook lists every task in order, with an owner, a time, and a rollback point. You approve it before any data moves, so launch day runs to a script.
We reconnect them to the new platform and test each with real orders before cutover. ERP, 3PL, tax, and email tools usually have connectors for the target platform, and the rest get small custom connections. Gateways move when the new platform supports your provider, and saved cards follow through token migration where it's offered.
Use a self-serve migration tool when your data is standard: products, customers, and orders without subscriptions, custom fields, or integrations. Tools are cheaper and fast for that job. A managed team earns its fee when saved cards, custom fields, connected systems, or a tightly timed cutover are involved.
Every plan includes 30 days of support after cutover. We watch integration logs, order flow, 404s, and rankings daily in the first week, and fix anything that surfaces. You also keep the final data map, the reconciliation report, and the runbook as a record of what moved.
