eCommerce Migration & Replatforming
Migrate Your eCommerce Store With Zero Downtime and SEO Preserved
Move from Shopify, BigCommerce, Magento, WooCommerce, Shift4Shop or PrestaShop with full data integrity, mapped 301 redirects, and post-launch support – across 1,000+ migrations in North America.
eCommerce migration is the process of moving an online store from one platform to another such as Magento to Shopify Plus, Shopify to BigCommerce, or WooCommerce to BigCommerce – while preserving products, customers, orders, SEO metadata, and 301 redirects without breaking organic traffic or losing customer accounts. The work includes data extraction, platform configuration, theme rebuilds, custom-code recreation, SEO preservation, ERP and integration validation, and post-launch QA. Replatforming is one of the highest-stakes projects an eCommerce business will undertake. Done wrong, it can erase years of rankings, disrupt customer access, and damage revenue while teams rebuild what should never have broken. Done properly, the new platform unlocks faster performance, stronger B2B functionality, better ERP integration, and international scalability that the previous system could not support. WebDesk Solution has delivered eCommerce migration services across major platform combinations including Magento to Shopify Plus, Shopify to BigCommerce B2B, WooCommerce to BigCommerce, and PrestaShop to Shopify with SEO fully preserved. We validate customer and order data, protect search visibility, recreate critical functionality, and launch stores without the chaos that usually follows a replatforming project.

SIGNALS
How do you know it’s time to migrate?
Most brands don’t replatform until they have to. By then, the cost of staying on the old platform – in lost conversions, plugin fees, dev time, and missed sales – already exceeds the migration cost. Below are the seven signals we see in nearly every store that finally pulls the trigger on B2B eCommerce replatforming or a full platform move.
Page speed has dropped below 3 seconds
Mobile LCP is the number-one conversion killer. If your old platform’s stack can’t deliver sub-2.5-second load, you’re losing 30%+ of mobile buyers before the cart loads.
You can’t add B2B features without custom dev
Tiered pricing, NET-30 invoicing, customer-specific catalogs – if your platform fights you on the basics, you’ve outgrown it.
Plugin and extension fees exceed your platform fee
When the apps cost more than the platform itself, you’re patching what should be native. A modern stack consolidates.
You can’t integrate with ERP, OMS, or PIM
Mid-market growth needs real integrations, not Zapier. Adobe Commerce, BigCommerce, and Shopify Plus all support this; legacy platforms typically don’t.
Your team is fixing recurring issues every week
Maintenance debt eats roadmap. If devs spend 30%+ of sprints on platform bugs, you’re paying replatform cost without the upside.
Headless or composable architecture is on your roadmap
Some platforms are headless-native (BigCommerce, Shopify Plus, Adobe Commerce); others can’t decouple. If headless is the future, plan the move now.
Your peak season broke last year
Black Friday revealing capacity ceilings is a forced replatform timeline. Plan now to ship before the next peak.
If two or more of these describe your store, talk to us before you spec the project – we’ll tell you whether replatform or refactor is the right call.
PLATFORMS
Which platform are you migrating to? Or away from?
We work across every major eCommerce platform – and most of the less-common ones. Pick your destination platform below. Each card opens our deep dive on that platform’s eCommerce platform migration services, common pitfalls, and what to expect. For brands evaluating eCommerce replatforming solutions across two or more platforms, we’ll help you choose.
DATA INTEGRITY
What gets migrated, exactly?
Every migration is a data project before it’s anything else. Below is everything our eCommerce data migration services transfer – grouped by category – and how we validate that nothing is lost in the move.
Products with full attributes, variants, and SKUs · Categories and collections · Brand and manufacturer data · Media (images, videos, downloadable files) · Inventory levels and locations
Customer accounts and credentials · Order history and order status · Wishlists and saved carts · Saved addresses and payment tokens (where the destination platform supports them) · Customer groups and segments
Coupons, discount rules, and gift cards · Reviews, ratings, and Q&A · Email subscriber lists · SEO metadata (title tags, meta descriptions, H1s) · 301 redirect mapping for every changed URL · Schema markup migration · Blog content with author attribution
Custom fields and metafields · CMS pages and editorial content · Third-party app data and configurations · ERP, OMS, and PIM connections · Payment gateway integrations · Shipping logic and rate tables
Need data migrated that isn’t on this list? We custom-map it. Talk to a migration specialist about your specific data model.
SEO PRESERVATION
How We Preserve SEO and Protect Rankings
Pre-migration SEO audit
Before any data moves, we crawl the existing site, document every indexed URL, capture current keyword rankings, save title and meta tags, and inventory schema markup. This is the baseline. Without it, the migration team is flying blind.
URL mapping and 301 redirect plan
Every old URL gets either a direct equivalent on the new platform or a 301 redirect to the closest match. We document the mapping in a spreadsheet your SEO team can audit. No URL gets lost without a destination – that’s the rule of eCommerce site migration done correctly.
Metadata and schema preservation
Title tags, meta descriptions, H1s, and schema markup (Product, Offer, BreadcrumbList, FAQPage, Article) all transfer. The new platform’s defaults are overridden where they would otherwise replace your hand-tuned versions.
Parallel-launch crawl and validation
Before DNS cuts over, we crawl the staging environment with Screaming Frog or equivalent and validate every redirect, every meta tag, every schema block. The goal: zero broken links in the first Google crawl after launch.
Post-launch monitoring (first 30 / 60 / 90 days)
We watch Google Search Console daily for the first 30 days, weekly to day 60, and monthly to day 90. Any ranking drop triggers immediate diagnosis. Most issues surface in week 2 or 3 – and by then the team is already on it.

PATHS
What’s the right way to migrate? Agency, tool, freelancer, or in-house?
There’s no universal answer – it depends on your store’s complexity and your team’s bandwidth. Here’s an honest comparison of the four common paths for eCommerce migration agency engagements, including when each one is the right call. We’ll tell you when an eCommerce replatforming consultant or freelance route is the better fit, even when it isn’t us.
| Agency (WebDesk Solution) | DIY tool (LitExtension) | Freelancer | In-house team | |
|---|---|---|---|---|
| Best for | Mid-market & enterprise ($1M–$50M+ GMV) | Small stores, simple catalogs, no custom code | Mid-budget stores with clear scope | Enterprise with mature dev team |
| Data integrity | Validated, custom-mapped, manually spot-checked | Automated, may miss custom fields | Depends on freelancer | Depends on team experience |
| SEO preservation | Full plan: audit, mapping, 301s, schema, validation | URL mapping only | Variable | Variable |
| Custom code rebuild | Yes – custom integrations, ERP, bespoke checkout | No | Limited | Full capability |
| Post-launch support | 30–90 day monitoring + triage | Email support | Hourly | Internal |
| Typical timeline | 8–14 weeks (mid), 14–24 weeks (ent) | 1–2 weeks data only | 6–16 weeks | 12–32 weeks |
| Typical cost (USD) | $25K–$200K+ depending on scope | $300–$2,000 | $5K–$30K | $50K–$500K loaded cost |
| Risk level | Lowest – accountable team | Medium – limited scope | Variable | Medium-high – context-switching |
If your store does $1M–$50M GMV, has B2B requirements, custom checkout, ERP integration, or 1,000+ SKUs – agency is almost always the right call. We’re happy to tell you when it’s not.
