Why 2026 is the year the fence-sitters moved

Most Magento merchants didn't wake up wanting a migration. The calendar and the invoice made the decision, and the data shows both at work.

• 01
  The support clocks ran out this year. Adobe Commerce 2.4.4 support ended April 2026; 2.4.5 ends August 2026. Merchants on either face a mandatory upgrade project (billable dev work on Magento) or accumulating PCI compliance risk. The ~14% of Magento stores still on end-of-life Magento 1 have been carrying that risk since June 2020.
• 02
  The operating cost gap widened. A comparable self-hosted Magento setup runs $4,000–$15,000+/month once hosting ($1,500–$5,000/mo), security patching, and dev resources are counted, against Shopify Plus at $2,300–$2,500/month on a multi-year term. For merchants under roughly $25M in annual revenue, that gap alone frequently tips the decision.
• 03
  The developer market keeps tilting. Magento-certified developers are scarce and day rates keep climbing as the pool shrinks; Shopify's developer pool is an estimated 5–10x larger at lower average rates. One agency's field note: Magento teams routinely spent six days per two-week sprint on upgrades, patches, and infrastructure alone.
• 04
  Adobe's own moves accelerated exits. The 2025 launch of ACCS (Adobe Commerce as a Cloud Service) came with a licensing push that sent mid-market Magento Open Source merchants — previously license-free — to evaluate their options. Adobe Commerce live stores fell 15% year over year to 114,607 in Q1 2026.
• 05
  The scale of individual moves is growing. March 2026 tracking recorded a single Magento-to-Shopify transfer of 267,626 data entities in one month. These aren't small stores cleaning house; established brands with a decade of data are running the route. Track how the flow develops in ECM Insights.
• 06
  The honest counterweight: some stores should stay. Catalogs past 100K SKUs with deep EAV logic, B2B motions built on negotiated quotes and approval chains, and teams with certified Magento devs running stable builds have a defensible case for staying — the full analysis is in the ECM Adobe Commerce vs Shopify guide. This article is for everyone else.

What the move costs, by Magento edition

Magento migrations price by architecture, not SKU count. The edition you're leaving and the custom logic you're carrying set the budget.

The budget ranges

• →
  Magento Open Source: $5,000–$40,000 over 6–12 weeks. Standard catalogs, limited custom modules, and a straightforward destination on core Shopify or entry Plus. Tooling (Matrixify, LitExtension, Cart2Cart) covers the data for $150–$500; the budget goes to theme rebuild, redirects, and QA.
• →
  Adobe Commerce: $25,000–$150,000+ over 3–6 months, and typically a Shopify Plus destination. UK agency benchmarks put a clean mid-market cutover at £30,000–£120,000 across 8–16 weeks. B2B, multi-store, and ERP-integrated builds stretch past $250,000; the integrations, not the products, drive the number.
• →
  Add the standard 25–40% contingency. The cross-industry base rate — 83% of data migration projects failing or overrunning — applies here with extra force, because EAV mapping surprises are the classic late-discovered scope. A documented failure costs $50,000–$500,000 in transition revenue, per post-mortems across 200+ DTC migrations.
• →
  The other side of the ledger is well documented: Bombas saved $108K in year-one platform costs; migrated brands report 2–4x lower three-year TCO, 10–20% checkout conversion lifts, and release cycles in weeks instead of quarters. Model your own three-year numbers in the ECM platform calculator before an agency proposal models them for you.

Timing the project

• →
  If you're on 2.4.5, the August 2026 support cutoff is your deadline, but a rushed migration into Q4 is worse than a patched limp through it. The clean paths are launch-by-early-October or start-in-January.
• →
  Budget the timeline by complexity: 6–12 weeks for Open Source, 8–16 weeks for standard Adobe Commerce, 3–6 months when ERP, B2B, or multi-store is in scope. The data transfer is days; the mapping, rebuild, and validation are the months.
• →
  One de-risking pattern from agency practice worth stealing: a canary cutover. One documented launch routed 10% of traffic to Shopify Plus on day one, caught a variant-bundle SKU mapping error in the ERP sync within hours, and fixed it while 90% of customers never saw it. Zero lost revenue.

EAV to metafields: the mapping that sets your real budget

Magento's flexibility is exactly what makes leaving it hard. Every structure below needs an explicit destination decision before any tool runs, and these decisions — not the transfer — are where projects burn time.

• 01
  Custom EAV attributes map to metafields, variants, or tags — and the relationship is rarely one-to-one. Shopify's metafields and metaobjects can absorb most relational attribute data, but deciding which attributes become which, deliberately and on paper, is the highest-leverage planning session in the project. Agencies consistently identify this as where Magento migrations either stay on budget or don't.
• 02
  Configurable products meet the 3-option, 100-variant ceiling. Magento configurables with four or more attributes must be restructured before import or Shopify drops the excess options silently. Complex bundles carry a second trap: variant-bundle SKU logic can trigger timeouts in Shopify Functions, so the working pattern is splitting bundles downstream in the ERP rather than recreating them in checkout logic.
• 03
  Customer groups become B2B catalogs and price lists. Since April 2026, core B2B (company accounts, catalogs, net terms) ships on every Shopify plan, which removed the old Plus-only barrier for simple wholesale. Map each Magento customer group to a catalog with price-list parity, and verify a sample of accounts sees the right prices before launch — this is the classic silent B2B migration failure.
• 04
  Multi-store views become Shopify Markets or expansion stores. Collapsing Magento store views carelessly into a single storefront is a documented failure mode; the decision between Markets (one store, localized) and Plus expansion stores (up to 10 storefronts) should be made on tax, catalog, and fulfillment differences, not convenience.
• 05
  Order history imports as read-only archives. Lifetime value, cohort reporting, and reorder attribution survive; the ability to modify or refund old orders doesn't. Brief the support team before launch. Customer passwords never transfer — the reset email is a comms project with a retention cost, so write it carefully.
• 06
  Every Magento extension needs a mapped equivalent, audited rather than assumed. List each module against the Shopify App Store and don't assume feature parity — the gaps you find here are your custom development scope. Run the inventory against a structured tech stack audit so nothing surfaces in week ten.

The redirect work, and what the case studies actually did

Magento migrations carry the highest SEO stakes in replatforming: years of accumulated URL equity meeting Shopify's fixed URL structure. The documented recoveries all ran the same sequence.

• 01
  Every URL changes, so every URL gets a 301. Shopify enforces /products/ and /collections/ paths that never match Magento's structure. Build the map from a full pre-migration crawl, rank pages by the traffic and revenue they carry, and decide the destination for every one — the practice the strongest migration agencies run before any design conversation happens.
• 02
  Done right, the equity survives almost entirely: roughly 98% of backlink value preserved with correct redirects. Done wrong, 30%+ of organic traffic disappears for months. An Ahrefs study's harder number looms over the whole exercise: 60% of pages that lose rankings in a migration never fully recover them.
• 03
  The recoveries are documented and repeatable. Eastside Co's Magento-to-Shopify project recovered rankings a botched Magento 1-to-2 upgrade had destroyed, then added 139,000 monthly organic sessions and 22,000 new keywords. Inflow's checklist-driven migration for Simms Fishing produced a 126% organic traffic increase. Both treated the migration as an SEO project with a commerce payload — the same discipline the platform-agnostic ECM migration checklist phases out step by step.
• 04
  Watch Magento's metadata specifically. Custom meta titles and descriptions stored in Magento attributes are the fields that most often arrive lost, truncated, or replaced with Shopify defaults. Verify your top collection, product, and blog pages against the pre-migration export, and restore anything that didn't carry.
• 05
  Validate before cutover, not after. Crawl the redirect map against staging, confirm your highest-traffic pages resolve correctly, and fix failures before DNS switches — cleanup during active recrawling is measurably harder. If organic drives meaningful revenue, a migration-experienced SEO specialist on this phase is the cheapest insurance in the project.

The migration sequence that produced the case numbers

Compressed from the agencies that run this route weekly. Five stages, in order, with the checks that matter.

• 01
  1. Discovery and audit (weeks 1–3): full catalog export to expose custom attributes, EAV complexity count, complete URL crawl, extension-to-app mapping, integration map (ERP, 3PL, ESP, loyalty), and a documented rollback plan. Pull baseline numbers — checkout conversion, organic sessions, page speed — from your core KPIs; the 90-day review is measured against this snapshot, not argued about.
• 02
  2. Mapping and build (weeks 3–10): the EAV-to-metafield decisions on paper first, then theme build (Liquid for most; headless Hydrogen only with a specific reason), B2B catalog configuration with price-list parity, and integrations rebuilt in staging. Performance targets from current agency practice: INP under 200ms, LCP under 2.5 seconds on mid-tier mobile.
• 03
  3. Data migration and validation (weeks 8–12): demo migration first, audited like an inspection — random products checked for variants and pricing, customers verified with order history attached, B2B accounts spot-checked for correct catalogs. Matrixify handles the Shopify side for most catalogs; the Admin GraphQL API covers anything custom.
• 04
  4. Cutover (launch week): redirect map validated against staging, content formatting hand-checked, a freeze window at your lowest-traffic hour with a final delta import, then DNS. If the store is large enough to justify it, the canary pattern — a traffic percentage routed to Shopify first — turns launch-day surprises into contained incidents.
• 05
  5. The 90-day close-out: Search Console monitored daily for two weeks, the organic dip held with nerve if the map was validated (the documented pattern: roughly 15% down in month one, recovered by month three), legacy hosting and licenses cancelled at day 30, and the review run against the Phase 1 baseline. Bombas' $108K year-one saving only counts because someone measured it.
