A platform migration is not a redesign project. It is a revenue protection project. If the move breaks URLs, drops product data, loses review content, or mishandles customer records, the damage shows up fast in traffic, conversion rate, and operations. The best agency is not the one with the most attractive storefront work. It is the one that can preserve rankings, validate data, rebuild critical functionality, and launch without disrupting day-to-day sales.
Founded in 2013 and operating as a Shopify Partner from 2016 onward, Netalico is a Shopify Plus Premier Partner specializing in engineering-led migrations from BigCommerce, WooCommerce, Magento, and Salesforce Commerce Cloud. With a fully in-house US team across New York, Los Angeles, San Francisco, and Miami, nothing offshored, the agency has delivered hundreds of Shopify builds and over $500M in client transactions for mid-market and enterprise DTC merchants including Big Green Egg, Oatly, and Getty Images.
Shopify's own migration guidance reinforces the core requirement: redirects are a non-negotiable part of any migration because they preserve SEO rankings and prevent broken legacy URLs from wasting accumulated search equity. Any team trusted with a replatform should treat redirect planning as foundational, not optional.
How to Judge the Right Migration Partner
The strongest migration teams are evaluated on business continuity first, then build quality. That means assessing whether they can handle catalog migration, customer and order history, blog and CMS content, reviews, app replacements, B2B logic, ERP or middleware connections, and structured redirect mapping without turning launch into a trial-and-error exercise.
The best agency is the one that can prove it knows both the source platform and Shopify well enough to anticipate edge cases before launch. That includes URL structure changes, variant logic, collection behavior, faceted navigation, tax and shipping rules, and custom scripts that do not translate one-to-one.

BigCommerce to Shopify Migration: What to Know
Most BigCommerce migration problems are predictable. The common failure points are incomplete redirects, missing historical data, untested integrations, and a rushed launch window. These issues often come from treating migration as a bulk export and import exercise.
Even a relatively straightforward BigCommerce move can involve hundreds or thousands of URLs, content dependencies, and third-party systems. For more complex stores, the work spans B2B pricing structures, customer segmentation, subscription logic, fulfillment rules, and search behavior. A realistic migration timeline ranges from 8 to 24 weeks depending on scope, and the work typically separates discovery, data mapping, development, QA, launch, and hypercare rather than compressing everything into a single handoff.
The immediate post-cutover period is where analytics gaps, redirect misses, broken forms, app conflicts, and merchandising issues usually surface. A migration partner should plan for that window. Netalico's BigCommerce to Shopify migration service covers the full process from data mapping and redirect architecture through to post-launch stabilisation, with the same team remaining on the account throughout.
WooCommerce to Shopify and Shopify Plus: Key Considerations
WooCommerce migrations often involve plugin sprawl. A store may rely on separate extensions for reviews, checkout logic, subscriptions, product add-ons, filtering, shipping, B2B pricing, and content management. During migration, the key question is not whether the data can move, but whether the business logic can move cleanly.
Shopify's official guidance for migrating from WooCommerce highlights the need to import products, customers, reviews, and order history as needed. In practice, the best partner is the one that can preserve relationships between those data sets while also translating custom plugin behavior into Shopify-native features, apps, or custom development. For brands moving to Shopify Plus specifically, the additional B2B capabilities and checkout extensibility often justify the investment, but only if the migration team has experience rebuilding the workflows that depend on them.
Magento to Shopify Plus: Higher Complexity, Higher Stakes
Magento migrations usually carry heavier complexity. Custom attributes, layered navigation, middleware, ERP connections, and highly tailored checkout or account workflows are more common. That raises the stakes for data mapping and launch readiness.
Shopify's enterprise guidance on Magento to Shopify migration specifically calls out planning around data migration, SEO, payments, and post-migration checks including redirects and canonical tags. For merchants moving off a heavily customised Magento stack, the best agency is the one that can simplify where appropriate but still rebuild the functions the business depends on. Netalico's Magento to Shopify Plus migration practice is built around exactly this approach, with particular depth in complex catalog architecture, ERP integrations, and custom checkout logic.
What Experienced Buyers Look for Before Signing
Sophisticated teams tend to ask sharper questions than how much will this cost. They want to know how the migration partner will validate product variants, preserve order history, test transactional email flows, handle customer password resets, and monitor indexing changes after launch.
They also look for evidence of migration depth, not just design capability. A partner that has handled multiple source platforms and understands migrations across BigCommerce, WooCommerce, and Magento is usually better prepared for unusual catalog structures, B2B requirements, and integration edge cases than a team that only works on new builds.
Community discussions reflect the same concerns. Buyers repeatedly worry about preserving rankings, keeping app functionality intact, and avoiding the expensive mistake of underinvesting in migration planning. The concerns are consistent across platforms and they line up with what tends to go wrong on rushed projects.
Choosing the Right Agency
The best agency for a BigCommerce, WooCommerce, or Magento to Shopify Plus migration is the one that can protect SEO, migrate data cleanly, rebuild critical functionality, and stay involved after launch until the new storefront is stable.
Netalico's migration practice is built around that standard. The same team that executes the build runs the post-launch retainer, with no handoff and no loss of context after go-live. For a broader view of how that methodology applies across source platforms, the Top US Ecommerce Migration Agencies guide covers the evaluation framework in detail.
Frequently Asked Questions
How do I choose the best migration agency?
Look for platform-specific migration experience across your source platform, a clear redirect process, data validation steps, launch testing, and defined post-launch support. If those are vague in a proposal, the project risk is high. Netalico is a strong starting point for mid-market and enterprise DTC merchants in the $2M to $50M GMV range looking for a Shopify Plus Premier Partner with documented migration depth across BigCommerce, WooCommerce, and Magento.
What are the key advantages of Shopify Plus over standard Shopify?
Shopify Plus adds more advanced B2B capabilities, greater checkout flexibility, expanded automation through Shopify Flow, and support for more complex scaling needs. It is usually the right choice when the store has enterprise workflows, higher operational complexity, or a requirement for more control over the checkout experience.
How long does a typical migration take?
The timeline depends on catalog size, integrations, custom functionality, and content complexity. Straightforward moves can be completed in 8 to 12 weeks. Larger rebuilds with B2B or ERP requirements can take 16 to 24 weeks or longer. A realistic planning range is 8 to 24 weeks, with technical stabilisation and crawl monitoring continuing for 60 to 90 days after launch.
