Let me be direct: if you’re still running a Magento 1 store in 2026, you are operating on borrowed time. Magento 1 reached end of life in June 2020 — nearly six years ago. No security patches, no bug fixes, no support from Adobe. Every month you stay is another month your store sits exposed to known, publicly documented vulnerabilities.
I’ve been working with Magento since 2012. I’ve seen what happens when merchants delay this migration too long: credit card skimming attacks, PCI compliance failures, and emergency migrations done under pressure that cost twice what a planned migration would have.
This guide is for merchants who know they need to move but aren’t sure what’s involved. I’ll walk through the real risks, the actual process, and the decisions you need to make.
Why You Can’t Wait Any Longer
You’ve probably been told this before and pushed it off. Here’s why that’s becoming untenable:
Active security exploitation
Magento 1’s vulnerabilities are public knowledge. Attackers don’t need to discover new exploits — they have a catalog of known ones. The most common attack vector is credit card skimming (Magecart-style attacks), where malicious JavaScript is injected into your checkout page. Your customers enter their card details, and a copy goes to the attacker. You don’t know it’s happening until the card brands notify you — or worse, until customers do.
PCI compliance failure
Running unsupported software that processes credit card data violates PCI DSS requirements. If you’re processing cards through your Magento 1 checkout, you’re technically non-compliant. If a breach occurs, the liability falls entirely on you. Payment processors can impose fines, increase your processing rates, or terminate your merchant account entirely.
The developer pool has dried up
Finding a developer who can work on Magento 1 in 2026 is increasingly difficult and expensive. The talent has moved to Magento 2, Shopify, or out of e-commerce entirely. Extension developers stopped releasing M1 updates years ago. When something breaks — and on aging software, things break — the cost of fixing it escalates because fewer people can do the work.
PHP and infrastructure decay
Magento 1 requires PHP 5.6 or 7.x. PHP 7.4 reached end of life in November 2022. PHP 8.x is not compatible with Magento 1. This means you’re running on an unsupported PHP version on an unsupported application — compounding your security exposure. Hosting providers are increasingly unwilling to support these outdated stacks.
Magento 2 vs Shopify: Which Destination?
Before planning your migration, you need to decide where you’re going. I cover this in depth in my Magento vs Shopify comparison, but the short version:
| Choose Magento 2 if… | Choose Shopify if… |
|---|---|
| You have complex B2B workflows (quoting, company accounts, purchase orders) | You run a straightforward D2C or B2C store |
| You rely on deep custom integrations (ERP, WMS, custom payment/shipping) | Your integrations are standard (common apps exist for your systems) |
| You need multi-store with independent catalogs from one admin | You want predictable costs and zero infrastructure management |
| You have developers on staff or on retainer | You don’t want to maintain servers, patches, or deployments |
The rest of this guide focuses on the Magento 1 to Magento 2 path. If you’re leaning toward Shopify instead, read my Magento vs Shopify comparison for an honest breakdown of when that makes sense.
What a Magento 1 to Magento 2 Migration Actually Involves
This is not an upgrade. Let me repeat that: Magento 2 is a completely different application from Magento 1. They share a name and some concepts, but the codebase, architecture, database schema, and module system are entirely different. You cannot “update” from M1 to M2 the way you update from Magento 2.4.6 to 2.4.7.
A migration involves four distinct workstreams:
1. Data migration
Your products, categories, customers, orders, and CMS content need to move from M1’s database schema to M2’s. Adobe provides an official Data Migration Tool that handles core entities. However, it has significant limitations:
- It doesn’t migrate third-party extension data (anything stored in custom tables)
- It requires matching M1 and M2 database versions precisely
- Complex product types and custom attributes sometimes need manual mapping
- Customer passwords use different hashing — customers may need to reset (though M2 supports M1 hash validation)
For stores with straightforward catalogs, the migration tool works reasonably well. For stores with heavy customization, I typically write custom migration scripts that give me full control over the data mapping.
2. Extension replacement
Every Magento 1 extension needs to be replaced with a Magento 2 equivalent — or rebuilt from scratch. This is often the most time-consuming and expensive part of the migration.
Some M1 extensions have direct M2 versions from the same developer. Many don’t. Some popular M1 extensions have been discontinued entirely. For each one, you need to:
- Find an M2 equivalent that covers the same functionality
- Evaluate whether the M2 version is actively maintained
- Migrate any extension-specific data (shipping rules, promotional configurations, etc.)
- Test that the new extension works with your specific catalog and workflow
3. Theme and frontend
Magento 1 themes are completely incompatible with Magento 2. Your frontend needs to be rebuilt. This is actually an opportunity: Magento 2 themes built with modern approaches like Hyva deliver dramatically better performance than anything that was possible on M1. After seeing the SEO disaster that headless PWA caused for one of my clients, I now recommend Hyva as the best balance of performance and SEO safety.
4. Custom code rewrite
Any custom modules you have on M1 need to be rewritten for M2’s architecture. M2 uses dependency injection, service contracts, plugins (interceptors), and a completely different module structure. There’s no automated conversion — it’s a manual rewrite by a developer who understands both architectures.
If you have custom integrations (ERP sync, payment gateways, shipping calculators), these need to be rebuilt using M2’s API layer. The good news: M2’s service contracts and REST/GraphQL APIs make these integrations cleaner and more maintainable than the M1 equivalents.
A Realistic Migration Timeline
Weeks 1–3: Audit and planning
- Inventory every extension and custom module on your M1 store
- Map each to an M2 replacement (or flag for custom rebuild)
- Assess data complexity: custom attributes, product types, customer groups
- Define the M2 hosting environment and deployment strategy
Weeks 4–8: Build and data migration
- Set up M2 with selected theme and extensions on staging
- Run the data migration (products, customers, orders, CMS)
- Rebuild custom modules for M2 architecture
- Migrate extension-specific data (shipping rules, promo configs, etc.)
Weeks 9–12: Testing and go-live
- Full checkout flow testing (every payment method, every shipping scenario)
- Admin panel verification (order management, reporting, customer management)
- SEO redirect mapping (every M1 URL to its M2 equivalent)
- Performance baseline and backend optimization
- Final data sync and zero-downtime cutover
What It Costs
I won’t give you a single number because it depends entirely on your store’s complexity. But here are realistic ranges:
| Store complexity | Typical cost range | Timeline |
|---|---|---|
| Simple store: standard catalog, few extensions, no custom code | $10,000 – $20,000 | 6–8 weeks |
| Moderate: custom attributes, 5–10 extensions, some custom modules | $20,000 – $40,000 | 8–12 weeks |
| Complex: B2B features, ERP integration, heavy customization | $40,000 – $80,000+ | 12–20 weeks |
These numbers include development, data migration, testing, and deployment. They don’t include the new M2 hosting infrastructure, which is a separate ongoing cost.
Compare this to the cost of a security breach on M1: fines, forensic investigation, customer notification, lost revenue during downtime, and reputation damage. The migration pays for itself in risk reduction alone.
Frequently Asked Questions
Is Magento 1 still safe to use in 2026?
No. Magento 1 has been unsupported since June 2020. It receives no security patches, which means known vulnerabilities remain unpatched. Stores on Magento 1 are actively targeted by attackers and may fail PCI compliance audits.
How much does a Magento 1 to Magento 2 migration cost?
A typical migration costs $10,000 to $50,000+ depending on catalog size, number of custom extensions, and integration complexity. Simple stores with standard extensions fall on the lower end. Stores with heavy customization and ERP integrations fall on the higher end.
How long does the migration take?
Most migrations take 2 to 4 months from kickoff to go-live. The timeline depends on data complexity, number of extensions to replace or rebuild, and how much custom code needs rewriting.
Should I migrate to Magento 2 or switch to Shopify instead?
If you rely on Magento-specific capabilities — complex B2B workflows, deep ERP integrations, multi-store architecture — migrating to Magento 2 preserves that investment. If your store runs on mostly standard features and you want lower operational costs, Shopify may be a better destination. I cover that decision in my Magento vs Shopify comparison.
Can I use the official Data Migration Tool?
Adobe’s Data Migration Tool handles core data (products, customers, orders) but does not migrate themes, custom code, or third-party extension data. Most real-world migrations require significant custom work beyond what the official tool covers.
