Quick Answer
A Magento to Shopify Plus migration for an enterprise store typically costs $80,000 to $200,000 and takes 4 to 7 months, depending on catalog complexity, the number of custom extensions being replaced, and whether B2B functionality is involved. The biggest hidden costs are data migration from Magento’s flexible EAV data structure and rebuilding custom extensions that have no direct Shopify equivalent.

Introduction
A Magento to Shopify Plus migration is one of the most consequential platform decisions an enterprise team can make — and one of the most frequently underestimated in terms of cost, timeline, and technical complexity.
Magento merchants are evaluating Shopify Plus in growing numbers. The reasons are consistent across nearly every conversation we have at NCM Technology: the operational burden of self-hosting, the cost of maintaining a development team capable of managing Magento’s architecture, and the appeal of a fully managed platform that handles hosting, security, and PCI compliance without a dedicated DevOps function.
But migrating away from Magento is not a simple data export and import. Magento’s architecture — particularly its EAV data model and deep extension ecosystem — creates specific technical challenges that catch many enterprise teams off guard. This guide covers what a Magento to Shopify Plus migration actually involves in 2024, what it costs, how long it takes, and the traps that turn a straightforward project into a budget overrun.
If you are still deciding which platform is right for your business, our Shopify Plus vs BigCommerce comparison and our full Shopify Plus development cost breakdown cover the broader platform decision in detail.
Why Merchants Are Leaving Magento in 2024
Magento — now split into Magento Open Source and Adobe Commerce since Adobe’s 2018 acquisition — remains a capable platform, particularly for businesses with complex catalog structures and large in-house development teams. But for many enterprise merchants, the total cost and operational burden has become difficult to justify.
In 2024, market data shows the shift clearly. Shopify Plus powers 8,338 enterprise businesses, representing 0.83% of the overall eCommerce market. Magento Enterprise (Adobe Commerce) powers 1,462 enterprise businesses, just 0.15% of the market. The gap has been widening for several years.
The primary drivers behind a Magento to Shopify Plus migration decision:
Total cost of ownership. Adobe Commerce licensing alone runs $40,000 to $200,000 or more per year depending on GMV and hosting tier. Add hosting, a dedicated development team or agency retainer, security patching, and PCI compliance management, and the all-in annual cost frequently exceeds what an equivalent Shopify Plus operation costs.
Operational overhead. Magento requires merchants to manage hosting, security patches, and PCI compliance directly. Shopify Plus includes all of this in the platform fee. For merchants without a large internal technical team, this difference alone often justifies migration.
App ecosystem breadth. Shopify’s app marketplace significantly exceeds Magento’s in size and ease of integration, meaning faster time-to-value for new functionality without custom development.
B2B feature maturity. Magento’s flexibility around customer groups, tier pricing, and shared catalog rules was historically the primary reason B2B merchants stayed on the platform. Shopify Plus B2B features matured significantly through 2023 and into 2024, closing much of this gap for typical B2B requirements.
This is not to say Magento is the wrong choice for every business. Merchants with extremely complex catalog logic, deep custom development requirements, and the in-house team to support it can still find Magento’s flexibility valuable. The migration decision should be based on your specific operational reality, not platform trend.
What Actually Breaks During a Magento to Shopify Plus Migration
Checkout UI Extensions are app-based components that add custom UI elements to specific positions within the Shopify checkout flow. They run in a sandboxed environment, cannot access sensitive payment data, and are upgrade-safe by design.
1. EAV architecture does not map cleanly to Shopify
Magento’s EAV architecture allows unlimited custom product attributes, complex configurable product structures, and highly flexible catalog data modeling. Shopify’s data model is comparatively rigid — based on a fixed set of product fields plus metafields for custom data.
Migrating a Magento catalog with extensive custom attributes requires mapping every custom EAV attribute to Shopify metafields, and in some cases, restructuring how product variants and configurable products are represented. For catalogs with dozens of custom attributes per product type, this mapping work alone can take several weeks and requires careful planning to avoid data loss or broken product relationships
Budget impact: $15,000–$40,000 depending on catalog complexity and the number of distinct product types requiring custom attribute mapping.
2. Custom extensions have no direct Shopify equivalent
Most enterprise Magento stores run with ten or more custom or third-party extensions handling functionality such as advanced pricing rules, custom checkout logic, loyalty programs, or B2B account management. Each of these needs to be either replaced with a Shopify app, rebuilt as a custom Shopify app, or reimplemented using Shopify Functions and Checkout Extensibility.
This is the most commonly underestimated cost category in Magento to Shopify Plus migration projects. Teams frequently assume “Shopify has an app for that” without verifying that the app actually replicates the specific business logic the Magento extension was handling.
Budget impact: $20,000–$60,000 depending on the number and complexity of extensions requiring replacement or custom rebuilding.
3. Multi-store structure requires rethinking
Magento’s multi-store and multi-website architecture allows significant flexibility in running multiple storefronts from one back-end, often with different catalogs, pricing, and configurations per store. Shopify’s equivalent — Shopify Markets for international selling, or separate store instances for genuinely distinct business units — works differently and may require restructuring how your business operates across storefronts.
Merchants running complex multi-store Magento setups should expect this restructuring to be one of the more significant architectural decisions in the migration, not a simple lift-and-shift.
4. SEO and URL structure preservation
Magento’s URL structure, canonical handling, and SEO configuration rarely match Shopify’s conventions exactly. A Magento to Shopify Plus migration without careful URL mapping and 301 redirect planning risks significant organic search traffic loss during and after the transition.
Every existing indexed URL needs a mapped redirect to its new Shopify equivalent. For large catalogs with thousands of indexed product and category pages, this redirect mapping is a substantial undertaking that requires dedicated SEO planning alongside the technical migration.
Budget impact: $8,000–$20,000 for proper SEO continuity planning and implementation on a large catalog.
5. Checkout customization expectations need resetting
Many Magento merchants have built highly customized checkout experiences using Magento’s open architecture — custom steps, complex B2B checkout logic, purchase order capture, and approval workflows. Shopify Plus’s Checkout Extensibility framework, while significantly improved through 2023 and 2024, operates within a more constrained model than Magento’s fully open checkout.
Teams migrating complex B2B checkout requirements should plan a discovery phase specifically focused on validating which existing checkout customizations are achievable in Shopify Plus and which require a redesigned approach.
6. Historical order and customer data migration
Migrating customer accounts, order history, and associated data such as loyalty point balances or subscription status requires careful planning, particularly for stores with years of historical data. Customer password migration is a common technical challenge, since password hashes are not portable between platforms — most migrations require a customer password reset flow post-launch.
Migration Cost Breakdown
| Project Component | Typical Cost Range |
|---|---|
| Discovery and technical audit | $8,000 – $15,000 |
| Data migration (catalog, customers, orders) | $15,000 – $40,000 |
| Custom extension replacement/rebuild | $20,000 – $60,000 |
| Storefront design and build | $20,000 – $60,000 |
| SEO continuity and redirect mapping | $8,000 – $20,000 |
| Checkout customization | $8,000 – $25,000 |
| QA, UAT, and launch support | 15–20% of total scope |
| Typical total | $80,000 – $200,000+ |
Migrations involving significant B2B functionality, multiple custom extensions, or large catalogs with deep EAV customization sit at the higher end of this range or above it.
Migration Timeline
A properly run Magento to Shopify Plus migration typically follows five phases:
Discovery and audit (4–6 weeks): Full technical audit of the existing Magento store, extension inventory, EAV attribute mapping plan, and SEO baseline documentation.
Architecture and planning (3–4 weeks): Defining the target Shopify data model, metafield structure, app replacement strategy, and migration approach for historical data.
Build (10–16 weeks): Storefront development, app configuration and custom development, checkout customization, and integration rebuilding.
Migration (3–5 weeks): Data migration execution, including catalog, customer, and order history transfer with validation at each step.
Launch and stabilization (2–4 weeks): Controlled cutover, redirect validation, monitoring, and rapid-response support for post-launch issues.
Total realistic timeline: 4 to 7 months for most enterprise migrations. Projects with extensive custom extensions or complex B2B requirements can extend beyond this range.
How to Reduce Migration Risk
- Run a full extension audit before scoping. Every custom and third-party Magento extension needs an explicit decision: replace with a Shopify app, rebuild as custom functionality, or eliminate if the business requirement has changed.
- Treat SEO as a dedicated workstream, not an afterthought. URL mapping, redirect implementation, and structured data validation need their own planning and QA process.
- Plan for a parallel run period if possible. Running both platforms briefly during transition, with careful order routing, reduces the risk of revenue disruption during cutover.
- Choose an agency with genuine Magento migration experience. Understanding Magento’s architecture, extension patterns, and EAV data structures is essential to scoping the project accurately.
Frequently Asked Questions
How much does a Magento to Shopify Plus migration cost?
A typical enterprise Magento to Shopify Plus migration costs $80,000 to $200,000, depending on catalog complexity, the number of custom extensions requiring replacement, and whether significant B2B functionality is involved.
How long does it take to migrate from Magento to Shopify Plus?
Most enterprise migrations take 4 to 7 months from discovery through launch and stabilization. The data migration and extension rebuilding phases are typically the longest components.
Will I lose my Google rankings during the migration?
Ranking loss is avoidable with proper planning, but it is one of the most common migration failures when not handled carefully. Every indexed URL needs a mapped 301 redirect to its Shopify equivalent.
Can all my Magento extensions be replaced with Shopify apps?
Not always directly. Many common Magento extension categories have Shopify app equivalents, but custom or highly specific business logic often requires either a custom Shopify app or implementation through Shopify Functions and Checkout Extensibility.
Is Shopify Plus B2B functionality mature enough to replace Magento’s B2B features?
For most typical B2B requirements — company accounts, tiered pricing, quantity rules, and purchase order workflows — Shopify Plus B2B functionality matured significantly through 2023 and into 2024. Highly complex requirements such as negotiated quotes or credit limit enforcement may still require custom development.
Should I migrate my customer passwords or require a reset?
Password hashes are generally not portable between Magento and Shopify due to different hashing algorithms. Most migrations implement a forced password reset flow for customers on their first login post-migration.
NCM Technology has migrated enterprise Magento stores to Shopify Plus with full technical audits, extension replacement planning, and SEO continuity built into every project. Migration projects start at $80,000.
