Can custom Magento modules be rebuilt?

Yes, custom Magento modules can be rebuilt when migrating to Shopify or another eCommerce platform. The module’s functionality and business requirements are first analyzed, and then similar features can be recreated using custom apps, APIs, platform extensions, or third-party apps. However, Magento code usually cannot be transferred directly, so the functionality must be redesigned and developed according to the new platform’s architecture, security standards, and capabilities.
