A meaningful number of mid-market retailers are still running Magento 1 in 2026, six years after the platform’s official end of life. The reasons vary – successful operations that did not want to risk disruption, replatform projects that stalled, business priorities that pushed the migration year after year, or skepticism that the migration ROI justified the disruption. The 2026 reality is that the structural risks of continuing on Magento 1 have accumulated to the point where the deferral cannot continue indefinitely for most retailers.
This article walks through the 2026 reality check – what running on Magento 1 actually means today, what the migration options look like, what the realistic timeline and cost are, and how to think about the decision when the right answer is no longer obvious. The framing is candid because the conversation deserves it; retailers who have deferred this long deserve real information, not generic urgency messaging.
The Security Situation Is Worse Than Most Retailers Realize
Magento 1 has not received official security patches from Adobe since June 2020. Third-party security patch providers (Mage One and OpenMage most notably) have filled some of the gap, but the coverage is incomplete and the cadence varies. New vulnerabilities discovered in 2024 and 2025 affecting components that overlap with Magento 1 (PHP versions, included libraries, ecosystem dependencies) are not consistently patched by the third-party maintainers.
The practical impact is that storefronts running Magento 1 in 2026 are operating in a known-vulnerable state for most of the time. Penetration tests typically surface vulnerabilities that have known exploits. PCI compliance assessments produce findings that require compensating controls. Cybersecurity insurance premiums reflect the elevated risk; some insurers no longer cover Magento 1 storefronts without explicit risk acknowledgment.
The retailers who have continued on Magento 1 are usually relying on a combination of WAF rules, infrastructure isolation, application-layer protections, and operational vigilance to compensate for the platform-level vulnerability. The combination can be effective but requires sustained discipline and accumulates technical debt. The compensating control approach also typically fails the security assessments that enterprise customers and large B2B partners increasingly require.
The Ecosystem Has Largely Moved On
Magento 1’s ecosystem of extensions, themes, and integrations has continued to shrink. Most major extension vendors stopped active development on their Magento 1 versions years ago. New extension capabilities are Magento 2 only. Theme vendors have similarly transitioned. Integration partners (payment gateways, shipping providers, ERP and CRM platforms) increasingly support only Magento 2 in their current integration libraries.
The practical impact is that Magento 1 storefronts have limited capability to adopt new business functionality. The team can build custom integrations, but the build cost is higher than buying off-the-shelf solutions that simply do not exist for Magento 1. The team can patch existing integrations, but the maintenance burden compounds as the upstream APIs evolve and the Magento 1 connectors fall behind.
The PHP version situation is a particular constraint. Magento 1.9 was designed for PHP 5.x and 7.0. Running on modern PHP versions requires either patches that break compatibility with various extensions or running on older PHP versions that themselves have end-of-life security implications. The combinations that work in 2026 are limited and getting more limited each year.
The Three Realistic Migration Paths
The first path is migration to Magento Open Source (Magento 2). The platform is free of license costs, has the largest ecosystem of extensions and integrations, and is what most Magento 1 retailers default to considering. The downside is operational complexity – self-hosting, security patching, maintenance, and infrastructure scaling are the retailer’s responsibility. The path works well for retailers with strong in-house ops capability or stable agency relationships.
The second path is migration to Adobe Commerce (the commercial version, formerly Magento Commerce). Adobe Commerce includes B2B features, advanced reporting, business intelligence integration, and Adobe-hosted infrastructure options (Adobe Commerce Cloud). The license cost is meaningful – typically $20,000 to $200,000+ annually depending on order volume and feature set – and the platform is more constrained in customization patterns. The path works well for retailers with B2B requirements or enterprise scale needs.
The third path is migration to a different platform entirely. Shopify Plus has matured to the point where many former Magento 1 retailers find it a better fit, particularly DTC brands with modest customization needs. BigCommerce, Shopware, and headless architectures on commerce backends like Commercetools are also legitimate options. The path works well when the original reasons for choosing Magento have changed and a different platform fits the current business better.
The decision among these paths should be informed by current business reality rather than legacy familiarity. A retailer who chose Magento in 2014 because it was the most flexible platform for their customization needs may find in 2026 that Shopify Plus has matured to cover most of those needs at a fraction of the operational complexity. A retailer who chose Magento because of the extension ecosystem may find Adobe Commerce a better fit now that B2B features are central to their roadmap. The migration is the natural occasion to reassess the platform decision rather than mechanically replicating it.
The Timeline Reality
Migration timelines for Magento 1 to Magento 2 (Open Source or Adobe Commerce) typically run six to fourteen months end-to-end for mid-market retailers, depending on complexity. The phases are discovery (six to ten weeks for thorough discovery, less for simpler stores), implementation (sixteen to thirty weeks depending on customization depth), data migration validation (two to six weeks), UAT (four to eight weeks), and stabilization (six to twelve weeks post-launch).
The data migration is one of the most underestimated phases. Magento 1 to Magento 2 data structures differ in ways that affect customer data, order history, catalog structure, pricing rules, customer segments, and integration data. The official Data Migration Tool handles the bulk of the standard data but does not handle customizations, extension data, or non-standard configurations. The custom migration work for those typically takes weeks and surfaces issues that require iteration.
The customization migration is the other underestimated phase. Magento 1’s module structure, layout XML approach, and frontend pattern differ fundamentally from Magento 2’s. Custom modules written for Magento 1 do not work on Magento 2 without rewrite. The estimate should account for the rewrite of every custom module, not just the ones with surface-level customization.
| Migration Variable | Lower Complexity | Higher Complexity |
|---|---|---|
| Custom modules | <10 | 30+ |
| Active extensions | <20 | 50+ |
| Custom checkout | None or minimal | Deep customization |
| B2B features | None | Heavy B2B usage |
| Integration count | <5 | 15+ |
| Custom theme depth | Light customization | Deep theme rebuild |
| Timeline range | 6–8 months | 12–14 months |
| Cost range | $120K–$280K | $450K–$900K+ |
The Cost Reality
Migration cost ranges vary widely. The clean mid-market Magento 1 storefront with limited customization, twenty or fewer extensions, and standard integrations typically migrates for $120,000 to $280,000 fully loaded. The complex storefront with deep customization, fifty or more extensions, complex integrations, and B2B functionality typically migrates for $450,000 to $900,000 or more. The variance reflects the customization depth more than anything else.
The cost should be evaluated against the alternative of staying on Magento 1. The alternative includes ongoing third-party security patching costs (typically $10,000 to $30,000 annually), the cost of compensating controls (WAF, infrastructure isolation, operational vigilance), the opportunity cost of not being able to adopt new integrations or capabilities, the cybersecurity insurance implications, and the eventual cost of emergency migration if a security incident or operational failure forces the timeline.
The financial case for migration works for most mid-market retailers when the analysis includes the full alternative cost. The retailers who have deferred this long usually underestimate the alternative cost because much of it (opportunity cost, insurance, operational overhead) is hidden across multiple budget lines. The full accounting typically produces a positive migration ROI within three to five years even on conservative assumptions.
What the 2026 Reality Looks Like
The retailers who have continued on Magento 1 through 2025 fall into three categories. The first is retailers who have a clear migration plan with specific timeline, vendor selection, and budget – these retailers are executing or about to execute. The second is retailers who have deferred decision-making and are operating with elevated risk but functional operations – these retailers should be making the migration decision now, not next year. The third is retailers who have decided to stay on Magento 1 indefinitely with full awareness of the trade-offs – these retailers are a shrinking minority, and the operational sustainability of the position is questionable beyond 2026.
The retailers who delay migration into 2027 or beyond are likely to encounter at least one of three forcing functions. The first is a security incident that surfaces the accumulated risk and creates emergency migration pressure. The second is a major business need (a new market, a new channel, a new customer requirement) that cannot be served on Magento 1 and forces the platform decision. The third is the gradual deterioration of operational viability as PHP versions, hosting providers, and ecosystem support continue to wind down.
The right time to migrate is when the retailer can do it deliberately rather than reactively. Deliberate migration produces better outcomes than emergency migration – better partner selection, better data quality, better customization rebuild, better staff readiness. The retailers who execute migration now have control over the process. The retailers who delay will eventually lose that control.
Bemeir’s Magento 1 to Magento 2 migration practice handles both Open Source and Adobe Commerce targets, and the discovery process explicitly includes the platform-decision conversation rather than assuming Magento 2 is the answer. For retailers whose business has evolved into territory where Shopify Plus fits better, Bemeir’s Shopify Plus practice supports that alternative. The honest conversation about which platform fits the current business is more valuable than the mechanical execution of a Magento-to-Magento migration that may or may not be the right move.
For deeper reference on Magento 1 EOL implications, the Adobe Commerce EOL announcement provides Adobe’s perspective, the Mage One security patch program and OpenMage provide the third-party patching context, and the Magento Data Migration Tool documentation describes the official migration tooling. Bemeir’s broader Adobe Commerce engagement model supports the full migration scope from discovery through post-launch stabilization.
