A Know what exists

Review Shopify’s upgrade report for the store.In Shopify admin, review the Thank you and Order status page upgrade status and every flagged customization. Copy every legacy additional script into a private configuration record.Record what it does, who owns it, and which destination receives its data. List every app pixel, custom pixel, and app integration.Include apps that claim to track purchases even if their placement is not visible in the theme. Find hardcoded Thank you page URLs, callbacks, and customer-account domain dependencies.These can fail even when the replacement page itself renders correctly. Identify the owner of each analytics, advertising, and messaging destination.Merchant, agency, former developer, or app vendor—someone must approve each decision.

B Decide before changing

Check app compatibility against the new pages.Retain compatible apps; do not replace them just to make the project look larger. Check for duplicate purchase sources.For each destination, identify every mechanism that can currently send the same purchase. Document the merchant’s consent instructions for every destination.The service follows and records the stated configuration; it does not provide legal advice or promise exhaustive validation of every consent state. Assign one decision to every source.Replace, retain, remove, update, verify, or document as out of scope.

C Change and observe

Record the pre-change state and platform limits.Shopify rollback is conditional and time-limited; legacy scripts cannot always be restored. Run one controlled order under an agreed condition.Record product, market, payment method, consent state, order identifier, timestamp, value, and currency. Check each destination through evidence it actually exposes.Record delays or unavailable diagnostics; do not invent a pass from silence. Save the final configuration map and duplicate review.Future operators should be able to see what changed, what was observed, and what remains assumed.
