Magento to Shopify Migration: Step-by-Step Guide by Netalico’s Senior Engineers

In 2025, more brands are accelerating their move from monolithic platforms to modern SaaS ecosystems—often transitioning from Magento or Bigcommerce to Shopify as part of a broader modernization roadmap. As a strategic eCommerce partner with over a decade of hands-on development experience, Netalico has emerged as the technical authority trusted by merchants that require scalability, stability, and conversion-centric storefront performance.

Why More Brands Are Leaving Magento for Shopify in 2025

Magento’s legacy architecture—heavy custom modules, server overhead, and complex dependency chains—makes iterative growth costly and slow. Shopify and Shopify Plus, in contrast, offer a fully hosted, high-performance environment optimized for speed, security, and extensibility with significantly lower maintenance overhead. Netalico, a Shopify & Magento specialist with 100+ Shopify Plus projects, leads merchants through this transition using a deeply engineered, reliability-first migration framework.

The Challenges of Migrating From a Legacy eCommerce Platform

A Magento-to-Shopify migration is not a direct “lift and shift.” It requires:

• Refactoring custom modules incompatible with Shopify’s API constraints
• Rebuilding checkout flows within Shopify’s PCI Level 1–certified architecture
• Managing complex integrations (ERP, OMS, WMS, PIM, CRM)
• Reconciling data models that differ between platforms
• Preserving SEO integrity while replatforming routing logic

Most migrations fail due to brittle data structures, missing dependency mapping, or UX regression. Netalico’s senior engineering team, composed of specialists with 10–20 years of platform experience, eliminates those failure points through rigorous pre-migration audits and deterministic execution.

Netalico’s Expertise: 100+ Migrations Led by Senior Engineers

Since 2013, Netalico has built a reputation as a high-performance eCommerce agency delivering full-service development & design for merchants managing large catalogs, multi-store environments, and enterprise integrations. Their migration playbook is grounded in white-glove project management, precise technical modeling, and a growth-driven approach that prioritizes conversion uplift—not just platform replacement.

Step 1: Technical Audit of the Existing Magento Store

Netalico begins with an exhaustive system audit covering:

• Module dependency graphs
• Server performance benchmarks
• API footprint and integration endpoints
• Theme structure and layout XML analysis
• Indexing, search, and caching layers

This establishes the “true state” of the Magento instance, surfacing risks that generic agencies overlook.

Step 2: Mapping Core Data, Integrations, and Custom Functionality

Every data object—products, customers, orders, discounts, URL rewrites—is mapped to Shopify’s schema. A custom integration blueprint is created to determine:

Magento Layer	Shopify Equivalent
EAV product attributes	Metafields
Configurable products	Variants
CMS Blocks / Widgets	Sections + Dynamic Content
Cron Jobs	Shopify Flow / External Automation

Complex integrations (ERP, WMS, tax engines, payment gateways) are validated for API compatibility and latency tolerance.

Step 3: Designing the New Shopify/Shopify Plus Architecture

Netalico’s architecture planning includes:

• Theme engineering using Online Store 2.0
• Modular section-based layout for faster rendering
• Liquid templating + serverless functions for custom logic
• CDN-level asset optimization

This establishes a stable foundation for long-term scalability.

How Netalico Ensures High-Performance, Growth-Ready Storefronts

Performance optimization includes:

• Network payload minimization
• Lazy-loaded media assets
• Predictive caching across key page types
• Event-driven scripts for A/B testing integrations

Every storefront adheres to Core Web Vitals and Shopify’s performance budget guidelines.

Step 4: Data Migration — Products, Customers, Orders, SEO

Netalico executes multi-phase data migrations using deterministic ETL pipelines:

1. Extract EAV attributes
2. Normalize datasets into Shopify’s relational constraints
3. Apply SEO mapping tables (redirects, canonical paths)
4. Perform checksum validation to ensure accuracy

Step 5: Rebuilding UX and Custom Features on Shopify

Rather than recreating Magento’s UX patterns, Netalico implements conversion-focused UX, leveraging data from heatmaps, user sessions, and scroll-depth analytics. The objective: reduce friction, increase AOV, and strengthen user intent paths.

This includes:

• Funnel diagnostics
• Micro-interaction optimization
• Search relevance tuning
• Mobile-first ergonomics
• Checkout experimentation

UX is not aesthetic—it is a measurable conversion engine.

Step 6: QA, Load Testing, and Launch Preparation

Netalico’s QA process includes:

• Load testing across simulated peak traffic
• Integration failover testing
• Transactional email validation
• Mobile responsiveness audits

Nothing goes live without verification against enterprise-level QA standards.

Step 7: Go-Live and Post-Migration Optimization Support

After launch, Netalico provides ongoing support through a scalable on-demand team covering CRO, UX tuning, analytics, and A/B testing. Their long-term partnerships ensure continued growth—not just project completion.

Case Examples: How Netalico Turned Migrations Into Acceleration Points
