For OpenCart alternatives, create a test catalog that includes your hardest product and shipping rules.
- Import variants, images, prices, taxes, and stock.
- Run a payment through sandbox checkout, then refund and cancel it.
- Compare order status, notifications, customer access, and inventory changes.
- Inventory extensions and themes; identify custom code that must be rebuilt.
- Export order history and plan redirects for existing URLs.
A theme migration is not a store migration. Keep the current store available until orders, stock, and customer records reconcile.
