Magento 2 Migration Checklist: Everything You Need Before You Start

Most people underestimate Magento migration until they’re halfway through it. What looks like a platform upgrade on paper turns out to involve rebuilding your theme from scratch, replacing most of your extensions, remapping your entire database structure, and somehow keeping your SEO intact through all of it. 

One missed step and you’re chasing down missing order data or watching your organic traffic drop with no clear explanation. This Magento 2 migration checklist exists because that stuff is preventable. Work through it before the project starts, not after something breaks.

Doesn’t matter if you’re doing a Magento 1 to Magento 2 migration or coming from a different platform altogether. The things that go wrong are usually the same things, and they’re almost always the things nobody planned for.

Why Do You Need a Magento 2 Migration Checklist?

Here’s the thing about Magento migration: the architecture between Magento 1 and 2 is genuinely different. Not “slightly different.” Different enough that themes won’t transfer, most extensions need replacing, and your database won’t map cleanly without preparation.Teams that skip the planning phase tend to find out mid-launch that their custom checkout logic was never rebuilt. Or they watch organic traffic slide because nobody set up redirects. Or they realise post-launch that half the order history didn’t come across.

A proper Magento migration checklist forces those decisions earlier, when they’re annoying instead of catastrophic. The upside is real:

• You know exactly what data is moving before migration day
• Your dev team has clear scope from the start
• SEO impact gets managed rather than discovered
• Launch day stays a launch, not a crisis response

When you hire Magento developers they usually follow a checklist to keeps things running smoothly. 

Pre-Migration Planning Checklist

Analyze Your Current Magento Store

Start here, not with Magento 2. Audit what you actually have before thinking about what you want.Go through your existing store and document every active extension, every piece of custom development, your current page speed benchmarks, and any bugs or technical debt that’s been sitting there for months. That last part matters. Migration is a reasonable time to leave old problems behind rather than carry them into a new platform.

Define Migration Goals

Write down what you want from the new store that you don’t have now. Faster checkout? Better mobile performance? Ability to handle a larger catalog? It sounds basic, but teams that skip this end up with vague scope and endless revision cycles.

Common goals worth spelling out:

• Improved site speed and Core Web Vitals scores
• Cleaner admin experience
• Better third-party integrations
• Support for multi-store or multi-currency setups

Choose the Right Migration Approach

When you migrate to Magento 2, you’ve got three real paths:

1. Data migration only – Move your products, orders, and customers. Rebuild the front end fresh.
2. Full rebuild – Start from scratch. Worth considering if your old store was a mess of patches and workarounds.
3. Hybrid approach – Migrate what’s usable, rebuild selectively. Most stores land here.

This choice shapes the timeline and budget for everything that follows. It’s worth getting right.

Backup Your Existing Store

Non-negotiable. Before anyone touches anything:

• Full database backup
• All media files and uploads
• Exported configuration settings
• Everything stored off-server, not just locally

If something breaks mid-migration and there’s no clean backup, recovery becomes very expensive and very slow.

Data Migration Checklist

Identify Data to Be Migrated

Not everything in your old database deserves a seat on the new platform. Start with what clearly needs to come across:

• Products, prices, images, and attributes
• Customer accounts and address books
• Order history
• Category structure and navigation
• CMS pages and static content blocks

Then make a deliberate decision about everything else. Old guest orders, abandoned carts, archived products. They add volume. They don’t always add value.

Clean and Optimize Data

This is the step that gets skipped most often. Duplicate customer records, discontinued products nobody deleted, inconsistent attribute values, broken category assignments. Migrating that into Magento 2 doesn’t fix any of it. It just moves the problem.Clean before you migrate. It’s less painful now than later.

Plan Data Mapping

Magento 1 and Magento 2 store data differently, so you’ll need to map things out before anything moves:

• Attribute sets and custom product attributes
• Customer groups
• Tax classes and pricing rules
• Order status labels

Get this documented. Data landing in the wrong fields is one of the harder problems to debug post-migration.

Design and Development Checklist

Redesign or Upgrade Theme

Magento 1 themes don’t work in Magento 2. There’s no workaround. You need a new theme, full stop. Your options are buying a compatible one and customising it, building something custom from scratch, or using Luma or Blank as a developer starting point.While you’re making that decision, factor in mobile performance. Magento 2 can score well on Core Web Vitals, but only if the theme is built with that in mind from the beginning.

Rebuild Custom Features

Every piece of custom functionality from your old store needs to be re-evaluated. The Magento 2 upgrade checklist on the development side typically includes:

• Rewriting custom modules using Magento 2 module architecture
• Rebuilding checkout modifications
• Re-implementing custom pricing or discount rules
• Retesting all integrations with external systems like ERP, PIM, or CRM

Don’t assume old custom code can be adapted. It usually can’t. Plan to rewrite it.

Review Extensions and Integrations

Most Magento 1 extensions don’t have a direct Magento 2 equivalent. For each one you’re currently running:

• Check whether a Magento 2 version exists from the same vendor
• Look at alternatives on the Magento Marketplace if not
• Confirm compatibility with your specific Magento 2 version
• Test everything in staging before it goes anywhere near production

SEO and URL Structure Checklist

This is where a lot of Magento migration steps fall apart. SEO damage from a badly planned migration can take months to reverse.

Maintain URL Structure

Magento 2 handles URL keys differently from Magento 1. Where you can, keep the same URL structure for product pages, category pages, and CMS content. If the URLs match on both sides, no redirects are needed for those pages. That’s the cleanest outcome.

Set Up 301 Redirects

For everything that can’t keep its URL, set up a 301 redirect to the new destination. This is how you protect rankings during a Magento 1 to Magento 2 migration.

Build the redirect map before launch:

• Export all indexed URLs from Google Search Console
• Map each old URL to its new equivalent
• Implement via Magento’s URL rewrite tool or at the server level
• Test every single redirect before anything goes live

Backup SEO Data

Export and store before migration:

• All meta titles and descriptions
• Product image alt text
• Canonical tag settings
• Current sitemap structure

These need to be replicated in Magento 2. Missing metadata is a quiet but effective way to lose rankings.

Testing Checklist Before Launch

Functional Testing

Work through every major user flow on staging:

• Search, filtering, and product browsing
• Add to cart, cart edits, and removal
• Guest and logged-in checkout end to end
• Account creation and login
• Order confirmation emails triggering correctly
• Admin order management and fulfilment

Test edge cases too. Out-of-stock behavior, configurable products with multiple variants, tier pricing, and coupon codes all have a habit of breaking in ways that aren’t obvious.

Performance Testing

Run load tests before touching production. Check:

• Page load time under normal traffic
• Server behavior under peak load
• Database query performance
• Full Page Cache functioning as expected

If staging is slow, production will be slower. Sort it now.

Security Testing

Before launch, do a proper security review:

• Admin panel URL should be non-default
• File permissions checked and tightened
• SSL configured correctly across the whole store
• Common vulnerabilities tested (SQL injection, XSS)
• Third-party extensions reviewed for known security issues

Go-Live Checklist

Final Data Sync

In the hours before switching over:

• Run a delta migration to capture orders and customers created after the initial data pull
• Verify product counts match across old and new stores
• Confirm inventory levels are accurate

Monitor Website Performance

For the first 48 hours after launch, watch closely:

• Server error logs
• 404 rate in Google Search Console
• Page speed metrics
• Checkout conversion rate

Have a rollback plan. If something critical breaks, you want to know exactly what you’re doing next.

Check Payment and Checkout Flow

Place real test transactions and then refund them. Verify:

• Every payment method completes successfully
• Order confirmation emails fire correctly
• Orders appear in admin with the right details
• Tax and shipping calculations are accurate

Post-Migration Checklist

Monitor SEO Performance

Track weekly after launch:

• Organic traffic against pre-migration baseline
• Crawl errors in Google Search Console
• Index coverage for key pages
• Ranking positions for your main keywords

Minor fluctuations over the first four to eight weeks are normal. Significant drops need immediate attention.

Fix Bugs and Errors

Keep a live bug log. Prioritise by impact:

• Checkout errors first (direct revenue)
• Product display issues second (conversion)
• Account functionality problems third (customer experience)

Most post-launch issues surface in the first two weeks. Stay on it. Support from eCommerce Development Services can be helpful here.  

Optimize for Performance

Once things are stable, work through performance tuning:

• Full Page Cache configuration
• Image compression and delivery
• JS and CSS minification and bundling
• CDN setup

Common Magento Migration Mistakes to Avoid

Skipping Backup

Teams that skip backups and hit a data corruption mid-migration have nowhere to go. The backup is not optional.

Ignoring SEO Impact

SEO gets treated as an afterthought in most eCommerce migration checklists. It shouldn’t be. URL mapping, redirect setup, and metadata replication need to be planned before development starts, not after launch.

Not Testing Properly

Launching without thorough staging tests is one of the most reliable ways to have a bad launch week. A broken checkout found by a real customer is a different problem from one found in QA.

Choosing Wrong Extensions

Picking poorly reviewed or untested Magento 2 extensions to replace Magento 1 ones creates new problems immediately. Vet everything before it goes into the build.Want to build a new Magento store without these complications? Our Magento Development Services can help you! 

Quick Magento 2 Migration Checklist

When to Consider Professional Magento Migration Services? 

Some stores are straightforward to migrate. Most aren’t. Bring in professional Magento development services help if:

• Your store has substantial custom development that needs re-architecting
• You can’t afford downtime during the switchover
• Your internal team doesn’t have hands-on Magento 2 experience
• You’re dealing with a large catalog or high order volume
• A previous internal attempt has already run into trouble

Professional Magento migration planning isn’t just about having someone execute the technical steps. It’s about having someone who knows which steps get skipped and what happens when they do.

Conclusion

A Magento 2 migration is a serious project. The stores that come through cleanly are the ones that planned a Magento 2 Migration checklist before they start. They backed up before they moved data. They tested before they launched. They treated SEO as part of the project, not a follow-up task.

Work through this magento migration checklist phase by phase. The checklist will help avoid complexities and delays. Need professional help for your migration? Connect with our Magento Support & Maintenance for a smooth and strategic transition.

FAQ

What is Magento 2 migration?

It’s moving your store from an older Magento version or a different platform over to Magento 2. Sounds simple. In practice it means rebuilding your theme, replacing extensions, remapping your database, and making sure your products, customers, and order history all land correctly on the other side. It’s closer to a rebuild than an upgrade.

How long does Magento 2 migration take?

Honestly, it depends. A smaller store without much custom development can get through it in four to six weeks if things go smoothly. Larger stores with complex integrations or years of custom work built up are usually looking at three to six months. A Magento Development Company can give you the right timeline. Teams that try to rush it are also usually the ones with the messiest launches.

Will I lose SEO rankings during migration?

Not if someone actually plans for it. The rankings don’t disappear because of the migration itself. They disappear because URLs changed and nobody set up redirects, or metadata didn’t carry across, or half the pages got deindexed by accident. A reputed Magento Development Company handles those things properly and your rankings stay largely intact. Ignore them and you’ll be doing damage control for months.

What data can be migrated to Magento 2?

Most of what matters. Products, categories, customer accounts, order history, CMS pages, URL rewrites. Magento has a Data Migration Tool built specifically for moving from Magento 1, though running it without prior experience tends to produce interesting results. Having someone who’s done it before makes a real difference here.

Do I need professional help for Magento migration?

For a genuinely simple store, maybe not. For anything with custom features, third-party integrations, or a catalog that’s grown over years, professional Magento migration planning is usually the cheaper option when you factor in what a failed migration actually costs to fix.
