We reverse-engineer the source data, business rules, integrations, content, and operational workflows, then rebuild them around a maintainable Shopify architecture.

A custom platform migration starts with source discovery

There is no standard export or assumed data model. We establish how the platform actually works, who owns each system, and what the Shopify store must preserve.

Source data discovery

Databases, APIs, files, media, identifiers, relationships, data quality, history, and change frequency are documented before extraction.

Business rule reconstruction

Catalog, pricing, promotions, accounts, checkout, tax, fulfillment, permissions, and edge cases are translated into explicit requirements.

Integration architecture

ERP, PIM, WMS, CRM, identity, payments, tax, search, marketing, analytics, and internal tools receive clear Shopify ownership.

How a custom platform is mapped into Shopify

We identify databases, APIs, exports, files, asset stores, identifiers, relationships, volumes, update frequency, ownership, and data quality. A source-of-truth map is agreed before migration code is written.

Products, variants, configurations, bundles, pricing, inventory, markets, customer-specific rules, promotions, and merchandising structures are translated into Shopify products, catalogs, metafields, metaobjects, Functions, apps, or services.

Customer identities, authentication, profiles, permissions, addresses, companies, consent, orders, payments, returns, and service-history requirements are mapped with security and customer communication in mind.

CMS content, templates, navigation, search, media, metadata, structured data, legacy URLs, tracking, consent, feeds, and reporting are inventoried so the new storefront launches with measurable continuity.

Every connection and manual workflow is traced through triggers, data direction, schedules, errors, retries, owners, and support needs before it is rebuilt around Shopify.

Our custom platform migration process

1. Technical discovery

We inspect architecture, databases, APIs, exports, repositories where available, hosting, vendors, security constraints, and system owners.

2. Requirements reconstruction

Business rules and operational workflows are documented through data evidence, user interviews, storefront behavior, and integration traces.

3. Shopify target architecture

Catalog, identity, B2B, content, checkout, integration, analytics, and operational needs are assigned to a maintainable target model.

4. Migration pipeline and rehearsals

Repeatable extraction, transformation, loading, exception handling, and reconciliation are built and tested with representative data.

5. Parallel validation

Data, storefront, integrations, security, operations, reporting, SEO, and customer journeys are validated against agreed acceptance criteria.

6. Controlled transition

The final sync, traffic switch, redirects, integration cutover, rollback responsibilities, monitoring, and support coverage are coordinated.

Migration decisions you can trace

Custom migrations succeed when assumptions are replaced with evidence. We create a traceable map from source behavior to Shopify so undocumented legacy logic does not become a launch-day surprise.

Custom platform to Shopify Migration FAQ

Yes. We can work from APIs, database access, structured exports, files, or a controlled combination. Discovery confirms what is available, the data quality, and whether any source engineering is required.

We combine source data, storefront behavior, code or API evidence where available, integration traces, operational reports, and interviews with the people who run the system. Important rules become documented acceptance criteria.

Often, but the right implementation may use Shopify products, variants, metafields, metaobjects, catalogs, Functions, apps, or external services. We design around the commercial requirement rather than copying the legacy database shape.

We review the identity model, password constraints, permissions, consent, profiles, companies, and connected systems, then define a secure Shopify account migration and customer communication plan.

The migration pipeline is run repeatedly with reconciliation reports. We test the final delta, integration switching, redirect activation, operational handoffs, acceptance checks, rollback ownership, and monitoring before launch.

We crawl the public site, supplement it with route and analytics data where available, inventory canonical URLs and content, map permanent redirects, validate metadata and internal links, and monitor indexing after launch.

Migration risk assessment

What we review before your Custom platform migration

The assessment establishes what can be extracted, what must be rebuilt, where risk sits, and how the transition can be rehearsed.

Source feasibility

Data access, APIs, exports, identifiers, relationships, volumes, history, quality, and update patterns are reviewed.

Rule and workflow inventory

Catalog, pricing, identity, checkout, payments, tax, fulfillment, service, permissions, and edge cases are documented.

Integration boundaries

System ownership, data direction, events, schedules, errors, security, vendors, and support responsibilities are mapped.

Transition strategy

Rehearsals, acceptance criteria, freeze and delta approach, rollback ownership, traffic switch, and monitoring are planned.

You receive a scoped migration approach, major risks, dependencies, and the decisions needed before implementation.
