Do we lose years of historical conversion and revenue-attribution data when migrating a custom platform's tracking setup to Shopify?
Historical revenue survives a move to Shopify; session attribution does not. Imported orders can keep the date Shopify's reports use (Shopify developer docs, October 2026). Sessions stay behind because Shopify counts them only on its storefront (Shopify Help Center, October 2026). Google Analytics 4's standard properties cap event-level data, not aggregated reports, at 14 months (Google Analytics Help, October 2026).
