Migrating from Magento Open Source to Adobe Commerce: What It Actually Costs and Changes

At some point, a Magento Open Source store stops feeling like a smart, cost-efficient choice and starts feeling like a set of walls closing in. Maybe it's the third-party extension that breaks every time you patch something. Maybe it's a B2B client asking for a quote-to-order flow your platform simply can't do without bolting on two more plugins. Maybe your traffic doubled last quarter and your single database is starting to show it.

If any of that sounds familiar, you're likely already circling the same question a lot of growing merchants land on: should we move to Adobe Commerce? This guide walks through what actually changes when you make that move, what it costs on top of the license fee nobody quotes you upfront, and how the migration itself runs from the first audit to a live store.

Signs Your Magento Open Source Store Has Hit Its Ceiling

Nobody migrates platforms for fun. It's usually one of a handful of pressure points building up until the cost of staying put outweighs the cost of moving.

Your B2B side is held together with extensions. Company accounts, tiered pricing, quote requests, purchase orders. None of this exists natively in Open Source. You can patch it together with third-party modules, but every one of them is its own update cycle, its own compatibility risk, and its own point of failure.

Your catalog has outgrown a single database. Open Source runs on one database by default. That's fine at a few thousand SKUs. At tens of thousands, with configurable products and heavy traffic, it starts to strain, and the usual fixes (caching, a well-tuned Elasticsearch setup, a beefier server) buy time rather than solve the underlying limit.

Patching security updates has become a part-time job. On Open Source, you apply Adobe's patches yourself. If your team is small or stretched thin, patches slip. Magento 1 stopped getting security patches back in 2020, and the stores that hadn't moved off it by then found out exactly what that exposure costs.

You need to talk to someone when something breaks. Community forums are genuinely useful, but at two in the morning before a big sale, they don't have a phone number. Adobe Commerce comes with direct support and defined response times built in.

If two or three of these sound like your Tuesday, the conversation about Adobe Commerce isn't premature. It's overdue.

What Actually Changes When You Move to Adobe Commerce

Both editions run on the same Magento 2 core, so the migration isn't a rebuild from scratch the way moving off an entirely different platform would be. What changes is everything layered on top of that core.

B2B functionality that used to require three separate extensions comes built in: company account hierarchies, contract pricing, quote-to-order workflows, credit limits, requisition lists for repeat orders. Codilar's native B2B commerce features work is built directly on this foundation rather than bolted on top of it. Search moves from a self-configured Elasticsearch setup to Adobe's AI-driven Live Search, tuned to actually understand product intent rather than just matching keywords. Content staging lets your marketing team schedule and preview changes before they go live, instead of pushing straight to production and hoping. And infrastructure stops being your problem in the same way. Adobe Commerce Cloud hosting bundles managed infrastructure, auto-scaling, and a CDN, so a traffic spike during a flash sale is something the platform absorbs rather than something your on-call developer fights at midnight.

None of this is exotic. It's the set of features that Open Source deliberately leaves out, on the assumption that stores needing them are ready to pay for them.

Magento Open Source vs Adobe Commerce, Side by Side

The differences are easier to see laid out side by side than described in paragraphs. Open Source costs nothing to license but leaves hosting, B2B functionality, and support entirely on you. Adobe Commerce charges a license fee tied to your Gross Merchandise Value, generally somewhere between $22,000 and over $125,000 a year, but folds in managed hosting, native B2B tools, AI-driven search, and direct support in return.

Neither edition is objectively better. A lean B2C store doing under $5 million a year with a competent dev team usually gets more value staying on Open Source. A store clearing $5 million with real B2B demand, or one that's simply tired of being its own infrastructure team, usually finds Adobe Commerce pays for itself faster than the license fee suggests.

What the Migration Process Actually Looks Like

A migration isn't a weekend project, and treating it like one is how stores lose data or tank their search rankings. When Adobe Commerce migration experts run this properly, the work moves through three distinct phases.

Audit and discovery comes first. Every extension, every line of custom code, every third-party integration gets catalogued, along with your actual data volume and where your current setup breaks under load. This is also where SEO gets mapped: existing URLs, metadata, canonical tags, everything that needs to survive the move intact. Skip this step and you find out what you missed the hard way, mid-migration.

Replatform and migrate is the technical core. Adobe's Data Migration Tool moves settings, then customer, product, and order data, then any changes that happened after the initial pull, so nothing gets lost in the gap between starting the migration and going live. Extensions get rebuilt or replaced with Adobe-native equivalents where they exist. Themes get reworked for the new frontend. Old and new stores typically run in parallel during this stretch, with data syncing between them, so there's no moment where the business is flying blind.

Hypercare and optimize covers go-live and the weeks right after it. Cutover happens with a rollback plan ready in case anything doesn't hold under real traffic. Once the store is stable, the actual optimization starts: turning on personalization, tuning Core Web Vitals, activating the B2B features that were the reason for the move in the first place.

For context on scale, this is the same playbook used to move a catalog of over 500,000 SKUs from Magento 1 to Adobe Commerce 2, with zero data loss, full SEO preservation, and a 50%-plus performance gain, in a timeline of four to thirteen weeks depending on complexity. Most migrations aren't that large, but the discipline in the process doesn't change based on catalog size.

What It Costs, and What It Saves You Later

The license fee is only part of the number. A realistic budget also accounts for migration services (data transfer, extension rebuilding, testing), any custom development your store needs that isn't covered by Adobe's out-of-the-box features, and a short stretch of parallel running costs while old and new systems sync.

Where this evens out is on the other side of the ledger. Stores currently on Open Source aren't paying a license fee, but they are paying for hosting, for extensions (individual modules often run $100 to $500 each, with a full B2B setup sometimes running $2,000 to $10,000 in extensions alone), and for developer time keeping all of it patched and compatible. Add that up for a moderately complex Open Source store and total cost of ownership regularly lands in the $50,000 to $150,000 a year range anyway, several of those costs simply bundled differently.

The honest crossover point: under roughly $5 million in annual GMV, Open Source usually still wins on total cost. Past $10 million, particularly with real B2B demand, the math tends to flip, since the features you'd otherwise pay to build and maintain piecemeal come included. It's also worth knowing that Adobe Commerce itself now spans more than one hosting model. If infrastructure control versus fully managed hosting is part of your decision, our breakdown of PaaS vs SaaS in 2026 covers how that choice affects cost and flexibility once you're already on Adobe Commerce.

Where Migrations Go Wrong (and How to Not Lose Your SEO)

Most migration failures aren't dramatic. They're a URL structure that shifted without a redirect, a canonical tag that didn't carry over, a product variant page that quietly dropped out of the index. None of it looks catastrophic on launch day. It shows up six weeks later as a traffic graph that never quite recovers.

The fix isn't complicated, it just has to actually happen. Every existing URL gets mapped before the move, with 301 redirects in place for anything that changes. Metadata, structured data, and canonical tags move with the content rather than getting rebuilt from scratch. Core Web Vitals get benchmarked before cutover and checked again after, so a slower new store doesn't quietly undo the SEO equity a faster old one had earned. Extension compatibility gets checked early, not discovered when a checkout flow breaks in production. None of this is hard. It's just easy to skip when a team is racing toward a launch date, which is exactly why it gets skipped so often.

Getting Started

If two or three of the pressure points from earlier in this guide sound like where your store is right now, the next move isn't necessarily a migration. It's an honest audit of what you're actually running: what's in your codebase, where your real bottlenecks are, and what a move would cost against what staying put is already costing you in developer time and workarounds.

Codilar has run this exact migration more than fifty times, including catalogs well past half a million SKUs, with zero data loss and SEO fully preserved on every one, including our migration work with Homes r Us, a 25,000-plus product furniture and decor catalog moved onto Adobe Commerce without disrupting the business.
