Magento 1 reached end of life in 2020. Stores still running on it receive no official security patches, struggle with modern PHP hosting, and fall further behind on payment, checkout and performance standards every year. A Magento 1 to Magento 2 migration is not an upgrade in place. It is a replatform: new architecture, new theme, new extensions and a data transfer. Done carefully, it protects your revenue and rankings. Done in a rush, it can cost both.
This guide explains the risks, the order of work, how to handle data and extensions, the SEO steps that keep your traffic, and what a realistic timeline looks like. The same plan applies whether you move to open source Magento 2 or to Adobe Commerce.
Why Staying on Magento 1 Is a Business Risk
- Security: no official patches means known vulnerabilities stay open, and card-skimming attacks commonly target outdated stores.
- PCI compliance: payment providers and auditors increasingly flag unsupported platforms.
- Hosting: Magento 1 depends on old PHP versions that hosts are retiring.
- Performance: slow pages hurt Core Web Vitals, conversion and paid ad quality.
- Talent: fewer developers want to maintain Magento 1 code, so fixes take longer and cost more.
Magento 2 or Adobe Commerce?
Magento Open Source is free to license and fits most small and mid-size stores. Adobe Commerce adds B2B features such as company accounts, quotes and shared catalogs, plus advanced content staging, customer segmentation and cloud hosting with support. Choose based on features you will actually use. Many brands run successful, fast stores on open source with a few well-chosen extensions.

Step 1: Audit Before You Touch Anything
Good migrations are won in the audit. Document:
- Every installed extension, what it does, and whether the business still needs it
- Custom code in local modules and the theme, including checkout and pricing logic
- Integrations: ERP, CRM, PIM, payment, shipping, tax, marketing and feeds
- Store structure: websites, store views, currencies and languages
- Catalog size, attribute sets, configurable and bundle products
- Your top landing pages and their organic traffic, from Search Console and GA4
The audit usually shows that a share of old extensions is no longer needed, which cuts migration scope immediately.
Step 2: Plan Extensions and Custom Features
Magento 1 extensions do not work on Magento 2. For each one, choose:
- Replace with a native Magento 2 feature, which is often possible for things like layered navigation improvements, page builder content or basic promotions.
- Replace with a maintained Magento 2 extension from a reputable vendor.
- Rebuild as a custom module when the logic is unique to your business.
- Drop it if nobody uses it.
Fewer extensions means faster pages, fewer conflicts and cheaper upgrades later.
Step 3: Migrate Data Safely
Adobe provides an official Data Migration Tool that moves settings, then core data, then incremental changes. Plan for these data sets:
- Products and categories: attributes, images, prices, inventory, related products and URL keys
- Customers: accounts, addresses and customer groups; passwords can carry over so customers can still log in
- Orders: history, invoices, shipments and credit memos for customer service and reporting
- CMS content: pages and blocks, which often need manual cleanup for the new theme
- Reviews, wishlists, coupons and gift cards where the business needs them
Custom extension tables are not covered automatically and need mapping files or custom scripts. Run the migration on a staging copy several times, compare record counts, and fix mapping issues before the final run. Clean data first: removing dead products, test customers and duplicate attributes makes every later step faster.
Step 4: Build the New Storefront
You have three common options:
- Standard theme: a Luma-based or lightweight custom theme. Lowest cost, familiar to most Magento developers.
- Performance-focused theme: a modern, lighter frontend approach that reduces JavaScript and improves Core Web Vitals.
- Headless or PWA: a separate frontend in a framework such as Next.js talking to Magento through GraphQL. More flexible and fast, with a higher build and maintenance cost. See our headless commerce development service.
Whichever you pick, rebuild checkout carefully and test every payment and shipping method end to end.
Step 5: Protect SEO During Migration
Most traffic losses after a replatform come from avoidable mistakes. Follow these steps:
- Crawl the old site and export every indexable URL, title, meta description, canonical and H1.
- Keep URLs identical where possible. Migrate URL keys and match category and product URL suffix settings.
- Create a 301 redirect map for every URL that changes, including old category paths, layered navigation URLs that earn traffic, and CMS pages. Redirect to the closest equivalent page, not the homepage.
- Carry over metadata and content: titles, descriptions, product copy, image alt text and structured data.
- Block staging from indexing with password protection, and remove that block at launch.
- Check canonicals, hreflang and robots rules on the new site before launch.
- Submit new XML sitemaps in Search Console at launch and monitor coverage and crawl errors daily for the first weeks.
- Compare top pages against your baseline and fix any drops quickly.
Some ranking movement after launch is normal while search engines recrawl. Large, lasting drops usually point to missing redirects or lost content.
Step 6: Test, Launch and Stabilize
- Functional testing of search, filters, cart, checkout, accounts and emails
- Integration testing with ERP, inventory, shipping and tax systems
- Performance testing with Varnish, Redis, Elasticsearch or OpenSearch configured
- A final delta migration of new orders and customers during a short freeze window
- A rollback plan and a monitoring checklist for launch day
Realistic Timeline
Timeline depends on catalog size, custom features and integrations. As a general guide:
- Small store with few customizations: commonly a couple of months
- Mid-size store with several integrations and custom features: often three to five months
- Large, multi-store or B2B setups: longer, usually phased
Avoid launching right before your peak season. Freeze major marketing changes during the final weeks so you can measure the migration cleanly.
Common Mistakes to Avoid
- Migrating every old extension and every old data table “just in case”
- Skipping the redirect map or redirecting everything to the homepage
- Changing URLs, design, catalog structure and pricing all at once
- Testing checkout only with one payment method
- No post-launch support plan
