A platform migration can affect organic rankings, particularly when URLs, content, page structure or technical settings change. Careful planning reduces avoidable risks, but no migration can guarantee unchanged rankings.

Costs depend on catalogue size, data complexity, design requirements, custom features, integrations and SEO work. We define the scope before providing a project quote.

A small store with standard products and few integrations may take several weeks. Larger stores with complex catalogues, custom functionality or extensive integrations may require several months. Data quality, approvals and testing also affect the schedule.

Manual migration can work for small catalogues with limited requirements. Tools can speed up standard data transfers but may not handle every custom field or business rule. An agency can coordinate data mapping, integrations, SEO, development and testing.

Passwords generally cannot be moved directly, so customers may need to activate accounts or reset passwords after launch. Planning this in advance can help reduce login friction and support queries.

Reviews and loyalty records need to be assessed for compatibility. Subscriptions need extra care because recurring billing agreements may not transfer automatically; customer communications and continuity should be planned.

Historical orders can often be imported, but some records may not support refunds, fulfilment or reporting in the same way. Agree the required history and test it before launch.

Some BigCommerce fields and features may not have a direct Shopify equivalent. Mapping your data and testing sample imports helps identify gaps before they affect customers or operations.
