Custom Platform to Shopify
questions.

A custom platform can provide code-level control and exact business behavior, but the business owns infrastructure, security, upgrades, key-person knowledge, and every extension. Shopify provides a managed commerce foundation with defined extension points. Compare differentiating requirements, control, maintainability, risk, integration needs, team capability, and total cost.

A migration can be planned from bespoke systems and platforms such as Shopware, PrestaShop, OpenCart, Volusion, Salesforce Commerce Cloud, SAP Commerce, commercetools, and other proprietary stacks when records can be extracted through APIs, databases, exports, reports, or controlled alternative methods. Feasibility and scope follow technical discovery.

We assess read-only database access, exports, reports, backups, files, event logs, existing integrations, and controlled extraction methods. The chosen path must be legal, secure, repeatable, and reconcilable. Unknown fields, relationships, encodings, attachments, and business rules become explicit discovery items.

Products, variants, customers, addresses, orders, content, files, pricing, inventory, companies, and other records can often move when the source is accessible. Every entity needs a system of record, field and relationship map, transformation rule, exception path, validation method, privacy decision, and archive requirement.

Yes where they remain valuable and fit Shopify’s extension model. Each rule should be mapped to native configuration, Shopify Functions, theme or checkout extensions, an app, Shopify Flow, an external service, or a redesigned process. Rules should not be copied merely because they exist in the legacy code.

Document each ERP, PIM, CRM, fulfilment, tax, payment, search, subscription, support, and reporting flow as a data contract. Define ownership, IDs, events, ordering, retries, reconciliation, alerts, security, manual fallback, cutover sequence, and legacy shutdown before implementation.

It can protect search value when the source URL estate can be discovered and mapped. Crawl the current site, combine analytics and Search Console evidence, classify retained and retired pages, implement redirects, validate rendering and metadata, update internal links, and monitor crawl, indexation, traffic, and revenue after launch.

Begin with a bounded discovery phase covering code, schemas, data samples, exports, integrations, traffic, operations, owners, risks, and extraction tests. The output is a migration inventory, architecture, mapping approach, assumptions, exclusions, proof points, phased estimate, rehearsal plan, cutover controls, and legacy-retirement decision.
