Adobe Commerce End of Support 2026 (What Merchants Must Do)

Adobe Commerce 2.4.4 support ended April 2026. Version 2.4.5 support ends August 2026. Shopify Scripts died June 30, 2026. Every legacy ecommerce platform is forcing merchants to make expensive decisions this year. Self-hosted Magento now costs 2 to 5 times Shopify Plus for the same operational scope. Manufacturers, distributors, and wholesalers on old stacks are being pushed off. This is the honest picture for legacy merchants in 2026.

What just happened in the legacy ecommerce market

Three deprecations in 2026 have compressed the legacy ecommerce migration timeline into a single 12 to 24 month window.

Adobe Commerce 2.4.4 end of life: April 2026. No more security patches, no more feature updates, no more official support. Merchants running 2.4.4 are one CVE away from a PR disaster.

Adobe Commerce 2.4.5 end of life: August 2026. The next tier of merchants faces the same cutoff four months later. Combined with 2.4.4, this represents the majority of self-hosted Adobe Commerce installations globally.

Shopify Scripts retirement: June 30, 2026. Any Shopify Plus merchant still running Scripts had to migrate to Functions by mid-year. Our Scripts post-mortem covers what actually happened.

The result: every serious ecommerce buyer with a legacy stack is being forced to plan migration in 2026. This is not a marketing narrative. This is a technical reality driven by platform vendors.

Who is being pushed off legacy platforms right now

The forced migration wave is hitting four specific segments hardest.

Manufacturers running Adobe Commerce. Typically B2B with catalog complexity, custom pricing per customer, and ERP integration. Their Adobe Commerce implementations were built over 3 to 8 years. Migration is not a weekend project.

Regional distributors on Magento or CS-Cart. Multi-location inventory, tiered pricing, warehouse-specific catalogs. Custom code accumulated over years. Every migration inherits this complexity.

Traditional wholesalers with custom quote workflows. Quote-to-order, credit terms, custom approval flows. Often built on Magento or a fully custom platform. Migration is the biggest technical decision they will make this decade.

Mid-market DTC brands on Magento Community or Open Source. Cost-optimized in 2018 to 2022 by picking free platforms. Now paying the compounding cost of self-hosted infrastructure. Migration is a cost reduction as much as a technology upgrade.

The real cost gap between self-hosted Magento and Shopify Plus

The pricing conversation is where most legacy merchants get their reality check.

Self-hosted Adobe Commerce or Magento total cost of ownership in 2026:

• Hosting infrastructure (AWS, Google Cloud, or dedicated): USD 1,500 to 4,000 per month
• Adobe Commerce licensing (if on the paid tier): USD 2,000 to 6,000 per month depending on revenue
• Security patches, updates, and DevOps: USD 500 to 2,500 per month
• PCI compliance and payment infrastructure: USD 200 to 800 per month
• Ongoing developer retainer for feature work: USD 3,000 to 8,000 per month

Total self-hosted Magento TCO: USD 4,000 to 15,000+ per month. Some enterprise Magento deployments hit USD 25,000+ per month all-in.

Shopify Plus TCO for equivalent scope in 2026:

• Shopify Plus subscription: USD 2,500 to 5,000 per month depending on GMV
• Apps for B2B, subscriptions, retention: USD 500 to 2,000 per month
• Ongoing development retainer (much smaller scope because Shopify handles infrastructure): USD 1,000 to 4,000 per month

Total Shopify Plus TCO: USD 4,000 to 11,000 per month. Materially cheaper at every scale.

The self-hosted Magento cost premium exists because merchants pay for infrastructure, security, and platform maintenance that Shopify absorbs into its subscription. That premium made sense when Shopify was retail-only. In 2026 with mature B2B and Plus features, the premium buys you nothing except operational risk. Our Plus pricing breakdown covers the full picture for Indian merchants specifically.

Why staying on unsupported Magento is dangerous

Six real risks facing merchants who choose to stay on unsupported Adobe Commerce past end of life.

1. Security vulnerabilities. No more security patches means every disclosed CVE stays open on your store. Attackers scan for known vulnerabilities. A single compromised checkout costs months of remediation plus lost customer trust.

2. PCI compliance failures. Your payment processor requires PCI-DSS compliance. Running an unsupported platform makes annual PCI audits harder and can trigger payment provider withdrawal.

3. Insurance implications. Cyber insurance policies typically exclude coverage for known vulnerabilities. Running unsupported software often voids the policy entirely.

4. Developer talent shortage. Shopify developers have been the growth market for a decade. Magento developers are increasingly hard to find, and the ones remaining charge premium rates. Your maintenance costs will rise even if you do nothing.

5. Extension deprecation cascade. Third-party Magento extensions follow the platform. As Adobe deprecates versions, extension vendors deprecate their support. Merchants find themselves patching modules by hand.

6. Compounding technical debt. Every year on an unsupported platform means another year of accumulated custom patches, workarounds, and undocumented fixes. Migration gets harder every quarter you delay.

CS-Cart merchants face similar pressure

Adobe Commerce is not the only legacy platform under pressure in 2026.

CS-Cart remains a functional platform but has minimal ecosystem growth. Merchants report increasing difficulty finding developers, extensions falling behind modern web standards, and hosting costs rising as PHP application requirements grow.

PrestaShop similar story. Open-source, functional, but developer talent pool shrinking. Custom modifications compound over years.

OpenCart aging platform with limited enterprise B2B features. Merchants who grew beyond simple retail typically outgrow it.

Fully custom ecommerce platforms built in 2015 to 2020 are the highest-risk category. Original developers have moved on. Documentation is thin. Every feature change costs 5 to 10 times what it would on a managed platform.

All four categories face the same forced migration pressure as Adobe Commerce, just without a specific end-of-life date driving the timeline.

The migration options - what to actually move to

Merchants considering migration in 2026 have four realistic destinations.

Shopify Plus. The dominant modern option. Managed infrastructure, deep B2B features (as of 2024 onwards), largest app ecosystem, best developer talent pool. Total cost typically 30 to 60 percent lower than self-hosted Magento for equivalent scope.

Adobe Commerce Cloud. Adobe's managed hosting version of Commerce. Solves the infrastructure problem but keeps the platform complexity and cost structure. Typically 20 to 40 percent more expensive than self-hosted Adobe Commerce plus Shopify Plus alternative. Right choice for merchants with heavy Adobe Experience Cloud integration.

BigCommerce Enterprise. Similar managed model to Shopify Plus. Smaller ecosystem, comparable pricing. Best fit for merchants with specific BigCommerce feature requirements or existing BigCommerce integrations.

Custom headless build. Highest cost, highest flexibility. Right choice only for merchants with unique requirements no managed platform can serve. Most B2B and wholesale operations do not fit this category.

For 80 percent of legacy Magento migrations in 2026, Shopify Plus is the correct destination. The remaining 20 percent split across Adobe Commerce Cloud, BigCommerce, and custom builds based on specific requirements.

Why Shopify Plus specifically for B2B and wholesale

Shopify B2B has matured significantly since 2023. Native features in 2026 include company profiles, catalog-level pricing, volume pricing tiers, configurable net payment terms, purchase order checkout, quick order forms, one-click reorder workflows, and company-level buyer permissions. Our earlier Shopify B2B guide covers what is built in versus what still requires custom apps.

For manufacturers and wholesalers migrating from Adobe Commerce, the Shopify Plus B2B feature set now covers 70 to 85 percent of what Adobe Commerce delivered natively. The remaining 15 to 30 percent typically requires custom apps or workflow adjustments. Total migration cost is materially lower than staying on Adobe Commerce for another 3 years.

Where Shopify Plus B2B still falls short of Adobe Commerce: multi-step approval workflows, complex contract pricing with annual commitment terms, and industrial B2B configurators. Merchants with these specific requirements should plan for custom app development alongside the migration.

The 12 to 24 month window - why urgency matters

The forced migration wave hitting the market in 2026 has a specific shelf life.

Migration agencies are booking up. Every Shopify Plus Partner in India, the US, and Europe is seeing spike inquiries for Magento migrations. Booking a quality agency in Q3 2026 for a Q1 2027 kickoff is realistic. Booking in Q1 2027 for a Q4 2027 kickoff means you launch on Shopify Plus in Q2 2028 - two years from now.

Adobe Commerce security exposure compounds. Every month past end of life adds vulnerability count. Merchants who wait until 2028 to migrate operate for two years on genuinely exposed infrastructure.

Developer talent gets scarcer. Magento developer supply shrinks as demand for Magento maintenance drops. Merchants who wait pay premium rates for scarce talent to keep aging systems running.

Migration costs rise year over year. Custom code accumulated between now and migration date is code that must be recreated or replicated. Every year of delay adds 10 to 20 percent to the eventual migration cost.

The merchants who complete migration in 2026 or early 2027 have a real cost advantage over merchants who wait. The demand spike is real. The window is finite.

What Magento to Shopify migration actually looks like

A realistic Magento to Shopify Plus migration for a mid-market merchant follows this pattern.

Phase 1: Discovery and scope (2 to 4 weeks). Full audit of current Magento setup. Custom modules, extensions, data model, integrations. Document every business rule currently implemented. Produce a signed scope document with fixed pricing.

Phase 2: Data migration setup (4 to 8 weeks). Products, customers, orders, historical data mapping. Custom scripts to transform Magento data schema into Shopify Plus data schema. Test migration on staging environment.

Phase 3: Theme and storefront build (8 to 16 weeks). New Shopify Plus theme built from scratch or adapted from existing brand design. Custom sections for B2B, quote workflows, and catalog features.

Phase 4: B2B and Functions configuration (4 to 12 weeks). Company accounts, catalog pricing, payment terms, custom Functions for discount logic. Testing with pilot customers.

Phase 5: Integration work (4 to 12 weeks). ERP integration, 3PL integration, accounting integration, PIM if applicable. Each integration is a subproject with its own timeline.

Phase 6: QA and cutover (4 to 8 weeks). End-to-end testing, load testing, parallel running with old Magento for 2 to 4 weeks, DNS cutover.

Total realistic timeline: 6 to 12 months for mid-market Magento migration. Enterprise migrations with heavy ERP integration can run 12 to 24 months. Our 8-week Plus migration timeline covers Shopify-to-Plus migrations specifically (much shorter).

What happens if I stay on unsupported Adobe Commerce past end of life?

Six specific risks compound over time. Security vulnerabilities accumulate as no patches release. PCI compliance audits get harder and payment providers may withdraw processing agreements. Cyber insurance policies typically exclude coverage for known vulnerabilities on unsupported software. Magento developer talent supply shrinks year over year, driving up maintenance costs. Third-party Magento extensions deprecate along with the platform, requiring hand-patching. Technical debt from workarounds compounds, making eventual migration harder and more expensive. Merchants who stay on unsupported Adobe Commerce for 12 months typically report meaningful security incidents or compliance headaches. Merchants who stay for 24 months typically have accumulated technical debt that costs 30 to 50 percent more to migrate away from later than migrating today. Adobe Commerce end of life is not a soft deadline. It is a hard deadline with compounding consequences.

How much does Adobe Commerce actually cost per month in 2026?

Self-hosted Adobe Commerce or Magento total cost of ownership in 2026 typically runs USD 4,000 to 15,000 per month for mid-market implementations. The breakdown covers hosting infrastructure (USD 1,500 to 4,000), Adobe Commerce paid licensing if applicable (USD 2,000 to 6,000), security patching and DevOps (USD 500 to 2,500), PCI compliance and payment infrastructure (USD 200 to 800), and ongoing developer retainer (USD 3,000 to 8,000). Enterprise Magento deployments with heavy customization can exceed USD 25,000 per month all-in. Shopify Plus TCO for equivalent operational scope typically runs USD 4,000 to 11,000 per month. The cost gap is materially real and grows as merchants scale, because Shopify infrastructure costs are fixed while Magento infrastructure costs scale with traffic.

Is Shopify Plus ready for B2B and wholesale in 2026?

Yes for the majority of B2B use cases. Shopify B2B in 2026 includes company profiles, catalog-level pricing per company, volume pricing tiers, net payment terms (net 15, 30, 60, or custom), purchase order checkout, quick order forms, reorder workflows, and company-level buyer permissions. These features cover 70 to 85 percent of what Adobe Commerce delivered natively. The gaps that remain are multi-step approval workflows, complex contract pricing with annual commitments, and industrial B2B configurators - these still require custom apps or workflow adjustments. For manufacturers, regional distributors, and traditional wholesalers migrating from Adobe Commerce, Shopify Plus is a viable destination in 2026 assuming a proper scoping exercise identifies the gaps upfront.

How long does Magento to Shopify migration take in 2026?

Realistic timeline for a mid-market Magento to Shopify Plus migration is 6 to 12 months of focused work. The breakdown covers discovery and scope (2 to 4 weeks), data migration setup (4 to 8 weeks), theme and storefront build (8 to 16 weeks), B2B and Functions configuration (4 to 12 weeks), integration work with ERP and 3PL systems (4 to 12 weeks), and QA plus cutover (4 to 8 weeks). Enterprise migrations with heavy ERP integration and complex B2B workflows can run 12 to 24 months. Compressing the timeline below 6 months for a proper Magento migration is generally not realistic and produces post-launch bugs that require another 6 months of stabilization. Plan for the realistic timeline rather than the marketed timeline.

What is the cost of Magento to Shopify migration in India in 2026?

Magento to Shopify Plus migration costs for Indian merchants in 2026 typically range from Rs 20 lakh for simpler migrations to Rs 1.5 Cr for complex enterprise B2B migrations. The typical mid-market migration lands between Rs 40 lakh and Rs 80 lakh covering discovery, data migration, theme build, B2B configuration, and 2 to 3 core integrations. Below Rs 20 lakh you typically get commodity migration work that leaves technical debt behind. Above Rs 80 lakh you enter enterprise territory with dedicated teams and multi-workstream execution.

Can CS-Cart, PrestaShop, or OpenCart merchants migrate to Shopify?

Yes, and these migrations tend to be simpler than Magento to Shopify because the source data models are less complex. CS-Cart to Shopify Plus typically takes 4 to 8 months for mid-market merchants. PrestaShop to Shopify Plus similar timeline. OpenCart to Shopify Plus often shorter because OpenCart implementations tend to be simpler. Cost ranges are similar to Magento migration though usually 20 to 30 percent lower because the data migration and B2B feature mapping is less complex. Fully custom platform migrations vary widely in complexity depending on how much custom logic must be reproduced in Shopify. Every custom platform migration needs a proper discovery phase to scope realistically.

What data can I migrate from Magento to Shopify?

Most operational data migrates cleanly. Products including variants, inventory, images, and metadata migrate directly. Customer accounts including addresses, order history, and account tags migrate. Historical orders with line items, fulfillment status, and refund records migrate. Categories and collections migrate with minor structural adjustments. What requires manual work: custom module data (product options, upsells, custom fields), historical CMS content beyond standard product and page data, custom customer group logic that does not map directly to Shopify's customer segments, and any custom promotional rule engine data. Modern Shopify migration tools handle 80 to 90 percent of the data automatically. The remaining 10 to 20 percent requires custom mapping scripts. Budget 4 to 8 weeks for data migration on a mid-market Magento project.

When should I start the Magento to Shopify migration if my Adobe Commerce version ends soon?

Now, if your Adobe Commerce version is 2.4.4 (already unsupported) or 2.4.5 (support ends August 2026). Migration takes 6 to 12 months. Adding 2 to 4 weeks for agency selection and contract execution means realistically starting the actual migration project in month 2 of your engagement. Even starting migration planning today gets you live on Shopify Plus around mid-2027. Merchants who wait until Q4 2026 to start planning are looking at Q4 2027 or Q1 2028 for go-live, which means running on unsupported Adobe Commerce for 18 to 24 months. The correct decision for most legacy merchants in 2026 is to start the discovery phase immediately, sign a migration agency by end of Q3, and commit to a Q2 2027 launch target.

The 12 to 24 month migration window is real. Adobe Commerce end of life is real. The cost gap between self-hosted Magento and Shopify Plus is real and material. Merchants who complete migration in 2026 or early 2027 will have a materially better operational cost structure than merchants who wait until 2028. Every month of delay adds cost, risk, and technical debt. This is the year to act.
