Direct answer: An effective Shopify migration includes a decision about what software and operational behaviour should move, change or be retired.
Create an application dependency map
List apps, plugins and custom integrations on the source platform. For each, document its business purpose, data it reads and writes, external owner, cost, access method, scheduled jobs and failure conditions. Not every plugin needs a Shopify replacement.
Separate native features from custom needs
Examine Shopify built-in functions, Shopify Flow, robust third-party apps, and carefully designed middleware before copying a legacy custom module. For subscriptions, investigate provider compatibility, contract migration constraints, customer consent and billing continuity.
Protect system-of-record integrity
Define which system owns product master data, inventory, payments, order states and customer records. Test identifiers, API limits, webhook delivery, retries, duplicate prevention, error handling and reconciliation. Preserve permission boundaries for systems receiving customer information.
Validate business outcomes
Check that order-to-fulfilment and return workflows work end to end, not only that an app installs successfully. CAT AI can dynamically prioritise integration mapping or validation work through its four frameworks, with expert oversight and clear stopping limits.
