Summary
Migrating to Magento 2 (Adobe Commerce) takes planning in six areas: data, extensions, theme, integrations, SEO and testing. Cost depends mainly on catalog size, custom code and the number of extensions that need rebuilding. A typical project runs from several weeks to a few months, and a staged migration with a final data sync keeps downtime to a few hours or less.
Introduction
Magento 1 reached end of life years ago, and many stores still run old versions with security and speed problems. Moving to Magento 2 fixes both, but it is not a simple upgrade. It is a rebuild of your theme, extensions and data on a new codebase.
This guide gives you a checklist, the factors that drive cost, and the risks to plan for. For help, see our Magento migration services.

What does a Magento 2 migration involve?
A migration moves your products, customers, orders and settings into a fresh Magento 2 install. Your theme and custom extensions cannot be copied across, so they are rebuilt or replaced.
The official Data Migration Tool handles most database content. Everything else is manual work.
What is the Magento 2 migration checklist?
- Audit the current store: products, extensions, custom code and integrations.
- Decide which extensions to keep, replace or drop.
- Set up Magento 2 on staging with hosting that meets its requirements.
- Migrate data using the Data Migration Tool, then clean up errors.
- Rebuild or choose a new theme and test on mobile.
- Reconnect payments, shipping, ERP and marketing tools.
- Map old URLs to new ones with 301 redirects.
- Run full tests, then a final data sync and go live.
What affects the cost of a Magento migration?
Cost is driven by scope rather than by the platform license.
| Factor | Lower cost | Higher cost |
|---|---|---|
| Catalog size | Under 1,000 products | Tens of thousands of SKUs |
| Design | Ready made theme | Custom design |
| Extensions | Few, all compatible | Many or custom built |
| Integrations | Standard payments and shipping | ERP, CRM, custom APIs |
| Hosting | Shared or managed basic | Cloud with scaling |
Ask for a written scope so testing, redirects and data cleanup are included in the quote.
How long does a Magento 2 migration take?
Simple stores can finish in six to ten weeks. Complex stores with many integrations often need three to six months.
The longest steps are usually extension replacement and testing, so start those early.
How do you keep your SEO during the migration?
Keep URL structures the same where you can, redirect every changed URL and carry over titles, descriptions and structured data.
Submit the new sitemap on launch day and watch Search Console for crawl errors.
Is Magento 2 the right choice, or should you consider other platforms?
Magento 2 suits complex catalogs, B2B pricing and heavy customization. If your needs are simpler, Shopify or WooCommerce can cost less to run. Read our Magento to Shopify migration guide to compare.
What mistakes make Magento migrations go wrong?
- Underestimating extension compatibility.
- No staging environment.
- Skipping the redirect map.
- Going live without a final data sync.
- Ignoring site speed and caching setup.
Which Magento versions need to be migrated?
Magento 1 stores must move, because that version no longer gets security patches. Many stores on early Magento 2 releases are also behind and should be upgraded to a current supported version.
If you are not sure what you run, check the admin footer or ask your developer. The answer decides whether you need a full migration or an upgrade. Our Magento upgrade services cover the second case.
How does the Magento Data Migration Tool work?
The official Data Migration Tool copies your database content, such as products, customers, orders and settings, into the new Magento 2 database. It runs in stages: settings first, then data, then a final delta sync for new orders.
The tool does not move your theme, your custom code or your extensions. Those are separate tasks, which is why a migration is closer to a rebuild than a simple copy.
Run it several times on a test copy before launch. Each run shows data errors you can fix, so the final run on launch day is clean and fast.
What happens to your extensions and custom code?
Extensions built for Magento 1 do not work on Magento 2. For each one, you have three choices: replace it with a Magento 2 version, replace it with a different extension, or rebuild the feature as custom code.
List every extension and ask whether you still need it. Many stores find that a third of them are unused, and dropping those saves cost, speeds up the store and reduces security risk.
- Keep: the extension has a Magento 2 version that fits.
- Replace: a better or more modern option exists.
- Rebuild: the feature is unique to your business.
- Drop: nobody uses it any more.
How should you handle the theme and site speed?
A migration is a good moment to fix speed. Modern themes and a clean extension list can cut load times a lot compared with an old Magento 1 store.
Plan for full page caching, image compression and a content delivery network. Test on a phone, since most shoppers browse on mobile. If you are considering a modern front end, see our work on Magento Hyva theme development.
How do you keep downtime close to zero?
The safest method is to build the new store beside the old one and keep both running. Customers keep ordering on the old store while the new one is tested.
On launch day, freeze the old store briefly, run the final delta sync for new orders, switch the domain and test a live order. With good preparation, this takes a few hours.
What should you monitor after the Magento 2 launch?
The first weeks after launch show whether the plan worked. Watch error logs, checkout success rate, page speed and Search Console crawl reports.
Fix redirect gaps quickly, because each missing redirect is a lost visitor and a lost ranking signal. Keep a short list of issues and review it every few days. If you want a partner for the process, see our Magento migration services.
How should you plan the budget for a Magento 2 migration?
Split the budget into five parts: discovery and planning, data migration, theme and design, extensions and integrations, and testing with launch support. Seeing them separately makes quotes easier to compare.
Keep a contingency of about fifteen to twenty percent. Unknown extension issues and data surprises are normal in Magento projects, and a reserve keeps them from stopping the launch.
Ask each provider what is included in testing and in the weeks after launch. Cheap quotes often leave these out, then charge for them later.
What hosting does Magento 2 need?
Magento 2 is heavier than many platforms, so hosting matters a great deal. It needs a modern PHP version, Elasticsearch or OpenSearch, a database with enough memory and a caching layer such as Varnish or Redis.
Shared hosting rarely works. Choose managed Magento hosting or a cloud setup that can scale for traffic spikes, and test it with real catalog data before launch. Slow hosting is one of the most common reasons a new Magento 2 store disappoints.
How does migration improve security and compliance?
Magento 1 no longer receives patches, which puts card data and customer records at risk and can cause problems with payment compliance. Moving to a supported version restores regular security updates.
Use the migration to tidy permissions, remove old admin accounts and enable two factor authentication. Our Magento security tips guide covers the settings worth checking after launch.
What does a typical Magento 1 to Magento 2 project look like?
Imagine a store with 5,000 products, twenty extensions and a custom checkout. The first step is an audit, which reveals that six extensions are unused and four have no Magento 2 equivalent.
The team keeps ten extensions, replaces four, rebuilds one feature as custom code and drops the rest. They migrate data into a test copy, run the tool three times and fix errors each round. A new lightweight theme replaces the old one, and page speed improves clearly.
Launch day involves a final sync of new orders, a domain switch and a live test order. The old store stays available for a month as a safety net.
What questions should you ask a Magento migration partner?
A good partner answers specifics, not slogans. Ask these before you sign.
- How will you handle my extensions, one by one?
- What is included in testing and post launch support?
- How will you protect my SEO and redirect old URLs?
- Who owns the code and the hosting accounts at the end?
- Can I see examples of similar migrations?
Who do you need on the project?
A migration needs a project manager, a Magento developer, a front end developer, a QA tester and someone from your side who knows the business. Small projects combine roles, but each task still needs an owner.
Name one person on your team to approve decisions quickly. Slow approvals are a hidden cause of delay and extra cost.
Conclusion
A good Magento 2 migration is planned, staged and tested. Know your scope, budget for extensions and redirects, and keep the old store running until the new one is stable.
