Frequently Asked Questions
Why did our old `checkout.liquid` scripts stop working on Shopify Plus, and how fast can you migrate them?
Shopify replaced `checkout.liquid` and Ruby Shopify Scripts with Checkout UI Extensions and WebAssembly Shopify Functions. Most custom checkout rules and UI blocks can be migrated cleanly in 1 to 2 weeks.
