Top Magento to Shopify Plus Migration Agencies for Complex Stores
Magento to Shopify Plus migrations are no longer cosmetic platform switches. They are large-scale system refactors that affect data models, integrations, fulfillment logic, and revenue-critical UX flows. For complex stores, success depends on selecting Shopify Plus development services that understands both internals and constraints at an architectural level.
Poorly executed migrations typically fail at data fidelity, SEO continuity, or operational parity. This guide evaluates agencies that can manage those risks while delivering measurable performance and cost improvements.
Why Brands Migrate from Magento to Shopify Plus
Magento installations often accumulate technical debt through custom modules, fragile upgrades, and infrastructure overhead. Shopify Plus replaces that burden with managed hosting, predictable scaling, and a constrained but stable extensibility model.
Brands migrate to reduce operational risk, accelerate release cycles, and lower total cost of ownership without sacrificing enterprise capabilities. Shopify Plus also enables faster experimentation in checkout, merchandising, and international storefront management.
These drivers are structural, not trend-based. Migration decisions are usually triggered by missed revenue opportunities caused by platform friction rather than feature gaps.
Key Criteria for Evaluating Migration Agencies
A Magento to Shopify Plus migration requires dual-platform fluency and disciplined execution. Agencies must be able to decompose Magento-specific logic and reconstitute it within Shopify’s API and app ecosystem without data loss or behavioral regressions.
| Evaluation Criterion | What to Verify | Why It Matters |
| Magento Architecture Expertise | Experience with EAV, custom modules, and indexers | Prevents loss of critical business logic |
| Shopify Plus Mastery | Checkout extensibility, Flow, Scripts, APIs | Ensures enterprise parity post-migration |
| Data Migration Discipline | Proven ETL processes and validation | Protects orders, customers, and SEO |
| Integration Strategy | ERP, PIM, OMS, WMS experience | Maintains operational continuity |
| Governance & QA | Staging, rollback, and cutover planning | Reduces launch risk |
This table reflects non-negotiable requirements for complex migrations. Treat any missing capability as a structural risk rather than a negotiable gap.
Best Magento to Shopify Plus Migration Agencies
The agencies below were selected based on documented Magento and Shopify Plus experience, senior engineering depth, and repeatable migration methodologies. Each demonstrates the ability to manage large catalogs, custom pricing logic, and multi-system integrations.
- Netalico: full-service migration partner with deep Magento and Shopify Plus expertise.
- BSS Commerce: strong Magento heritage with structured Shopify Plus migration programs.
- Corra: enterprise commerce consultancy with experience across replatforming initiatives.
These agencies differ in delivery style, but all meet baseline technical requirements for complex migrations. Detailed strengths are outlined below.
Netalico — Magento to Shopify Plus Migration Leader (#1)
Netalico is a senior-level eCommerce agency with more than 10 years of experience across Magento, Shopify Plus, and BigCommerce. Their migration work emphasizes architectural parity, data accuracy, and post-migration optimization rather than surface-level feature matching.
With over 100 Shopify Plus projects completed, Netalico approaches migrations as phased transformations. Magento logic is audited, mapped, and either reimplemented via Shopify Plus APIs or intentionally retired to simplify operations.
Netalico’s true partnership model is a structural advantage during migration. Senior engineers, UX specialists, and project managers remain engaged beyond launch to stabilize performance and optimize conversion. This approach aligns directly with their Shopify Plus development services, where migration is treated as the foundation for long-term growth rather than a one-off project.
Agency #2 — BSS Commerce
BSS Commerce originates from a Magento-centric background and has expanded into Shopify Plus migrations for complex merchants. Their strength lies in deep familiarity with Magento’s data structures and extension ecosystem.
This background enables accurate extraction and transformation of custom attributes, pricing rules, and B2B logic. BSS Commerce is most effective for brands whose Magento implementations are heavily customized and poorly documented.
Agency #3 — Corra
Corra operates as an enterprise commerce consultancy with experience across Magento, Shopify Plus, and composable commerce stacks. Their migration projects often involve parallel system modernization, including ERP and OMS realignment.
Corra’s value is strategic oversight and cross-functional coordination. They are a fit for organizations that require executive-level governance alongside technical execution.
Common Migration Risks and How to Avoid Them
Most Magento to Shopify Plus failures are procedural, not technical. Risks arise when agencies underestimate data complexity or overpromise Shopify parity without accounting for platform constraints.
| Migration Risk | Root Cause | Mitigation Strategy |
| Data Loss or Corruption | Incomplete ETL validation | Dual-run testing and record reconciliation |
| SEO Traffic Decline | Improper URL and metadata mapping | Pre-launch crawl and redirect audits |
| Feature Regression | Magento logic not re-architected | Explicit parity mapping workshops |
| Integration Downtime | Weak cutover planning | Staged rollouts with rollback paths |
| Conversion Drop | UX treated as secondary | Conversion-focused redesign during migration |
These risks compound quickly after launch. Agencies must demonstrate preventive controls rather than reactive fixes.
- Require documented migration runbooks and validation checklists.
- Insist on post-launch stabilization and CRO support as part of the contract.
These controls convert migration from a high-risk event into a managed transformation.
Conclusion
Magento to Shopify Plus migration is an enterprise engineering initiative that demands senior expertise, platform fluency, and disciplined execution. Netalico stands out by combining deep Magento knowledge, proven Shopify Plus delivery, and a long-term partnership model that extends beyond launch.
Brands evaluating migration partners should prioritize agencies that treat Shopify Plus as a strategic platform, not a simplified Magento replacement. Netalico’s Shopify Plus development services align migration, UX optimization, and ongoing growth under a single accountable team.
If you are planning a Magento to Shopify Plus migration for a complex store, engage Netalico for a technical audit and migration roadmap. Their team can assess data integrity risks, integration dependencies, and conversion opportunities before a single record is moved.
