In-house team

Conversion is a Shopify migration agency headquartered in San Francisco. We've replatformed 80+ stores to Shopify and Shopify Plus from Magento 1 & 2, WooCommerce, BigCommerce, Salesforce Commerce Cloud (Demandware), Shopware, and custom builds — for DTC and B2B brands across the US, Canada, UK, and Australia.

A migration isn't a rebuild with extra steps — it's a revenue-protection project. The organic traffic, customer accounts, and order history your store has accumulated are assets, and most failed migrations destroy them through skipped redirect mapping and sloppy data work. Our process treats SEO equity and data integrity as the deliverables, with the new storefront as the vehicle.

Why migrations go wrong

The three ways replatforming destroys revenue

We're regularly hired to rescue migrations gone wrong. The damage traces to the same three mistakes every time.

Blanket redirects instead of 301 mapping

Redirecting every old URL to the homepage tells Google your content is gone. Rankings collapse in 2–6 weeks and take a year to rebuild. We map every URL one-to-one — products, collections, blog posts, and the long tail — before cutover.

Data migrated once, validated never

Single-pass CSV imports silently drop variants, metafields, and order line items. We run staged dry runs with count validation and record spot-checks until the delta is zero — then a final freeze-and-sync at cutover.

Integrations discovered broken after launch

ERP sync, email flows, review widgets, and 3PL feeds fail on day one because nobody inventoried them. Our discovery phase maps every integration to its Shopify equivalent before we quote — so nothing is a surprise.

Migration services

Every platform, every data object

Our migration process

Five phases, zero surprises

Audit & redirect map

Full crawl and URL inventory, Search Console export, integration map, and data-object census. The one-to-one 301 map is built before any development starts — it's the project's foundation, not an afterthought.

Parallel build

The Shopify store is built on a preview domain while your current store keeps trading. Conversion-led templates, native structured data, and every integration connected and tested.

Data dry runs

Staged migration passes for catalog, customers, and orders — validated by counts and spot-checks after each pass until the delta is zero.

Cutover

Data freeze, final delta sync, 301 deployment, DNS switch in your lowest-traffic window. Typical downtime: zero.

90-day watch

Sitemap resubmission, redirect verification at scale, and weekly Search Console monitoring for 90 days. Any ranking decay gets diagnosed and fixed the week it appears.

Migration case studies

Replatformed without the horror story

Magento 2 → Shopify Plus — Home goods

ranking loss

14-week enterprise migration, organic traffic up 9% post-launch

“Every agency promised zero SEO impact. Conversion was the only one that showed us the redirect map before we signed. Organic traffic was up within 60 days of cutover.”

SFCC → Shopify Plus — Apparel

−52%

platform TCO

Off Demandware in 16 weeks, checkout conversion up 18%

“We cut our platform spend in half and our checkout converts better than it ever did on Commerce Cloud. Should have done this two years earlier.”

WooCommerce → Shopify — Supplements

74%

accounts reactivated

40K customers and 6 years of order history moved intact

“Our biggest fear was losing customer accounts and subscription revenue. The reactivation campaign brought back three-quarters of active customers in the first month.”

Why Conversion

The migration partner that shows its work

The redirect map before the contract

We build the URL inventory and 301 strategy during scoping — you see the SEO-protection plan before you sign, not after something breaks.

80+ migrations, every major platform

Magento, WooCommerce, BigCommerce, SFCC, Shopware, and custom builds. Platform-specific playbooks, not a generic import checklist.

Zero ranking loss as a reported metric

We report rankings and organic traffic weekly for 90 days post-launch against the pre-migration baseline. The bar is zero loss — and it's in the engagement.

Data validated, not just imported

Staged dry runs with count validation and record spot-checks. Variants, metafields, and order line items don't silently vanish on our migrations.

Fixed scope, 48-hour quote

A fixed-price quote within 48 hours of discovery, with the integration map and week-by-week roadmap included. No hourly-billing surprises mid-project.

A growth partner after cutover

Most clients move into CRO and SEO programs post-launch — on a pay-on-results basis. The migration is the start of the engagement, not the end.

Frequently asked

Shopify migration questions

How much does it cost to migrate to Shopify?

A focused migration to Shopify typically runs $15K–$60K; complex Shopify Plus migrations with ERP re-integration, large catalogs, and B2B data run $40K–$120K+. The main cost drivers are catalog size and complexity (variants, metafields), customer and order history volume, custom functionality to rebuild, integration count, and content migration. We deliver a fixed-scope quote within 48 hours of a 30-minute discovery call.

Will I lose SEO rankings when migrating to Shopify?

Not if the migration is done properly. We've completed 80+ migrations with zero ranking loss as the bar. That takes a full URL inventory before cutover, one-to-one 301 redirect mapping (not blanket redirects to the homepage), structured data preservation, internal link updates, XML sitemap resubmission, and 90 days of post-launch Search Console monitoring with a weekly ranking report. Traffic dips almost always trace to skipped redirect mapping — the single most common replatforming mistake.

How long does a Magento to Shopify migration take?

Most Magento 1 and Magento 2 to Shopify migrations run 8–14 weeks: 1–2 weeks for data audit and mapping, 4–8 weeks for build and data migration dry runs, and 2–3 weeks for QA, redirect verification, and cutover. Catalog size, custom module count, and ERP integrations are the main variables. We publish a week-by-week roadmap on day one.

Can you migrate my customer accounts and order history to Shopify?

Yes. We migrate customers (with account-activation flows so nobody loses access), full order history, product catalogs with variants and metafields, reviews, gift cards, discount codes, and blog/CMS content. Passwords can't be migrated between platforms for security reasons, so we run a branded reactivation campaign that typically recovers 60–80% of active accounts in the first month.

Should I migrate from WooCommerce to Shopify?

If you're spending more time maintaining WordPress plugins, PHP versions, and hosting than growing the store — yes. Shopify removes server maintenance, security patching, and plugin conflicts, and delivers a faster checkout out of the box. The trade-offs are platform transaction fees and less database-level control. We'll give you an honest total-cost-of-ownership comparison on the first call; for some content-heavy stores, staying on WooCommerce is the right answer and we'll say so.

Do you migrate from Salesforce Commerce Cloud (Demandware) to Shopify?

Yes. SFCC to Shopify Plus is one of our most common enterprise migrations. We map ISML templates and controllers to Shopify equivalents, rebuild business-manager workflows in Flow and Launchpad, migrate the catalog and customer data, and re-integrate ERP/OMS systems. Most brands cut their platform TCO 40–60% while gaining checkout conversion.

What happens to my integrations when I move to Shopify?

Every integration gets inventoried and mapped in the discovery phase: ERP, PIM, 3PL/WMS, email (Klaviyo), reviews, loyalty, subscriptions, and analytics. Most have native Shopify equivalents or official apps; the rest we rebuild as custom middleware or private apps. Nothing gets discovered broken after cutover — the integration map is part of your fixed-scope quote.

Can we migrate to Shopify without downtime?

Yes. We build and QA the new store on a preview domain while your current store keeps trading, freeze data at cutover, run a final delta sync of orders and customers, and switch DNS during your lowest-traffic window. Typical downtime is zero; checkout interruption is minutes, not days.
