About our migration practice

Replatforming is a revenue-protection project

  • San Francisco, USA

    In-house team

Conversion is a Shopify migration agency headquartered in San Francisco. Our Shopify migration services replatform 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. If you are still weighing the move, our WooCommerce vs Shopify and BigCommerce vs Shopify comparisons cover the trade-offs.

We run every migration as 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: one-to-one 301 mapping that hands over cleanly to a Shopify SEO program, conversion-led templates from our Shopify development team, and price lists and customer groups rebuilt with Shopify B2B when a wholesale operation is moving too.

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 to 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

Platform-specific migration playbooks refined across 80+ replatforms, in place of a generic import checklist.

  • Magento to Shopify

    Magento 1 (EOL) and Magento 2 migrations to Shopify and Plus. Attribute sets and configurable products mapped to Shopify variants and metafields, custom modules rebuilt as apps or Functions, and 40 to 60% lower total cost of ownership.

    • M1 + M2 → Shopify / Plus
    • Attribute → metafield mapping
    • Custom module rebuilds
    • ERP re-integration

  • WooCommerce to Shopify

    Off WordPress hosting, plugin conflicts, and PHP maintenance. Products, customers, orders, and blog content migrated; SEO plugins' structured data re-implemented natively; WordPress blog optionally retained or moved.

    • Products + orders + customers
    • Blog / content migration
    • Yoast data re-implementation
    • Hosting decommission plan

  • BigCommerce to Shopify

    Catalog, customer groups, and order history moved; BigCommerce-specific features (price lists, customer groups) rebuilt with Shopify B2B or apps; theme rebuilt conversion-first instead of ported.

    • Catalog + customer groups
    • Price list → B2B mapping
    • Conversion-led theme rebuild
    • Zero-downtime cutover

  • Salesforce Commerce Cloud to Shopify Plus

    Enterprise SFCC (Demandware) replatforms. ISML templates and controllers mapped to Shopify equivalents, Business Manager workflows rebuilt in Flow and Launchpad, and OMS/ERP integrations re-architected.

    • SFCC → Shopify Plus
    • Workflow rebuild in Flow
    • OMS / ERP re-architecture
    • 40 to 60% TCO reduction

  • SEO Preservation & 301 Strategy

    Full URL inventory, one-to-one 301 redirect mapping, structured data preservation, internal link rewrites, sitemap strategy, and 90 days of post-launch Search Console monitoring with weekly reports.

    • One-to-one 301 mapping
    • Structured data parity
    • Canonical + sitemap strategy
    • 90-day GSC monitoring

  • Data Migration & Validation

    Products, variants, metafields, customers, order history, reviews, gift cards, and discounts, migrated in staged dry runs with count validation, then a freeze-and-delta-sync at cutover.

    • Staged dry runs
    • Count + record validation
    • Customer reactivation flows
    • Order history preservation

  • Integration Mapping & Rebuilds

    ERP, PIM, 3PL/WMS, email (Klaviyo), reviews, loyalty, subscriptions, and analytics inventoried and mapped in discovery. Most have native Shopify equivalents or official apps; the rest we rebuild as custom middleware or private apps.

    • Integration map in the quote
    • ERP + PIM + 3PL/WMS
    • Klaviyo, reviews, loyalty
    • Custom middleware + private apps

  • Zero-Downtime Cutover

    The new store is built and QA'd on a preview domain while your current store keeps trading. At cutover we freeze data, run a final delta sync of orders and customers, deploy the 301 map, and switch DNS during your lowest-traffic window.

    • Preview-domain build + QA
    • Data freeze + delta sync
    • 301 deployment
    • Low-traffic DNS switch

  1. Platform, catalog and integration audit

    We audit your current platform and size the data and integration surface, including the custom functionality that would need rebuilding.

  2. The SEO-protection plan

    We build the URL inventory and 301 strategy during scoping, so you see the plan before you sign.

  3. A fixed-scope quote within 48 hours

  4. A straight answer on whether to move

    For WooCommerce stores we give a total-cost-of-ownership comparison on the first call. For some content-heavy stores, staying put is the right answer and we'll say so.

Our migration process

Five phases, zero surprises

  1. Step 01

    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, because it is the project's foundation.

  2. Step 02

    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.

  3. Step 03

    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.

  4. Step 04

    Cutover

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

  5. Step 05

    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.

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, so you see the SEO-protection plan before you sign.

  • Every major platform, one process

    Magento, WooCommerce, BigCommerce, SFCC, Shopware, and custom builds, each with a platform-specific playbook.

  • 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 at every pass

    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, so the migration is the start of the engagement.

Frequently asked

Shopify migration questions

What does a Shopify migration agency do?
A Shopify migration agency replatforms stores to Shopify and Shopify Plus from Magento 1 & 2, WooCommerce, BigCommerce, Salesforce Commerce Cloud (Demandware), Shopware, and custom builds. The work covers the catalog, customers, order history, integrations, and SEO equity: a full URL inventory, one-to-one 301 redirect mapping, staged data migration with validation, and post-launch monitoring, with the new storefront built conversion-first.
How much does it cost to migrate to Shopify?
A focused migration to Shopify typically runs $15K to $60K; complex Shopify Plus migrations with ERP re-integration, large catalogs, and B2B data run $40K to $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. Zero ranking loss is the bar on every migration we run. That takes a full URL inventory before cutover, one-to-one 301 redirect mapping (no 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 to 14 weeks: 1 to 2 weeks for data audit and mapping, 4 to 8 weeks for build and data migration dry runs, and 2 to 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.
How does the Shopify migration process work?
In five phases. We audit the current platform and build the one-to-one 301 redirect map, build the Shopify store on a preview domain while your current store keeps trading, migrate data in staged dry runs until the delta is zero, cut over with a data freeze and final delta sync in your lowest-traffic window, then monitor Search Console weekly for 90 days.
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 to 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 to 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. The integration map is part of your fixed-scope quote, so nothing gets discovered broken after cutover.
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, and any checkout interruption lasts minutes.
