All of that matters.

But enterprise ecommerce architecture usually extends far beyond the customer-facing interface.

A single transaction may depend on:

• ERP
• inventory management
• CRM
• PIM
• OMS
• payment systems
• tax services
• fraud detection
• loyalty infrastructure
• shipping platforms
• analytics
• marketing tools

If the project is planned primarily around the frontend, these backend dependencies become surprises later.

A better approach is to map the entire commerce ecosystem before defining migration scope.

The storefront is only the visible layer.

Enterprise platforms accumulate custom logic over many years.

Some of it is essential.

Some of it exists because of old limitations that no longer apply.

During migration, teams often assume that every existing behavior needs to be rebuilt.
