# Shopify’s non-Plus checkout migration deadline lands August 26 Non-Plus Shopify stores still using legacy Thank you and Order status pages face an August 26 auto-upgrade that can remove unsupported scripts, pixels and app customizations. Shopify’s August 26 deadline is a concrete compatibility cutoff for non-Plus stores. Legacy Thank you and Order status customizations must be rebuilt with supported blocks, web pixels or app pixels, or the automatic upgrade can break analytics and post-purchase behavior. - Status: Active - Published: 2026-08-18T21:46:48+12:00 - Updated: 2026-08-18T21:46:48+12:00 - Categories: Web Development, Developer Tools - Tags: checkout extensibility, migration, Order status, ScriptTags, Shopify, Thank you page, web pixels - Canonical HTML: https://beyondthe.news/dossiers/shopify-non-plus-thank-you-order-status-august-26-migration ## What changed Shopify says August 26, 2026 is the deadline for non-Plus stores to upgrade legacy Thank you and Order status pages. Stores that do not upgrade are auto-upgraded. Existing page customizations can be replaced, and unsupported additional scripts, apps that rely on legacy script tags and other deprecated customizations need supported replacements. ## Why it matters Post-purchase analytics, conversion tracking, upsells, custom messages and app behavior often live on these pages. An automatic page replacement can silently remove those behaviors unless merchants and app developers migrate before the cutoff and verify the resulting event flow. ## The deadline is for non-Plus stores Shopify's current non-Plus guide sets August 26, 2026 as the deadline. Plus stores followed a different earlier timetable, so teams should not reuse Plus migration dates or assumptions. ## Legacy customizations need supported extension points Shopify directs merchants to blocks for page functionality and design, web pixels or app pixels for tracking, and compatible apps for custom behavior. The upgrade guide surfaces installed apps that are compatible or still require developer action. ## Auto-upgrade can be operationally lossy If a store remains on the legacy pages after the deadline, Shopify says the pages are auto-upgraded. Because the old customizations are replaced, builders should treat this as a production migration rather than a cosmetic admin change. ## App developers have a customer-support obligation Apps that historically injected scripts or relied on deprecated extension points should provide supported replacements and clear migration instructions. Merchants cannot fix an incompatible third-party app solely from checkout settings. ## Key details - The non-Plus deadline is August 26, 2026. - Pause and Build stores are upgraded automatically. - The new pages are customized through Shopify's checkout and accounts editor. - Blocks replace page customizations; web pixels and app pixels replace legacy tracking patterns. - Shopify's personalized upgrade guide identifies existing customizations and incompatible apps. - Stores that do not upgrade before the deadline are auto-upgraded. ## Builder takeaways - Open Shopify's personalized upgrade report now and inventory every script, pixel and app attached to Thank you or Order status pages. - Replace analytics scripts with supported web/app pixels and validate purchase-event payloads end to end before August 26. - For custom apps, test the replacement extension point on a staging/development store rather than assuming a script-tag migration is behaviorally identical. - After migration, compare conversions and post-purchase events against backend order counts to catch silent tracking loss. ## What to watch - Whether Shopify publishes additional migration tooling or warnings immediately before the deadline. - Post-deadline reports of analytics or app regressions on auto-upgraded stores. - Further retirement of legacy checkout customization surfaces. ## Uncertainties - The exact impact varies by each store's installed apps and legacy customization stack; Shopify's personalized upgrade report is more authoritative than a generic checklist. - Some third-party apps may ship compatibility updates close to the deadline, changing a store's required work. ## Timeline - **2025-08-28 — Legacy additional scripts become view-only:** Shopify previously restricted editing of the legacy additional-scripts surface. - **2026-08-26 — Non-Plus migration deadline:** Remaining non-Plus stores are due to move to the new Thank you and Order status pages and can be auto-upgraded. ## Sources - [Non-Plus - Upgrading and replacing your Thank you and Order status pages](https://help.shopify.com/en/manual/checkout-settings/customize-checkout-configurations/upgrade-thank-you-order-status/upgrade-guide) — Shopify Help Center · primary.
