Moving to the WooCommerce Checkout block without losing orders
The block-based Cart and Checkout are now what new WooCommerce stores get by default, and older stores are being nudged towards them. The switch is a good one — but it is a new checkout, and extensions that hooked into the old one do not automatically work in the new one.
Why things break
The classic checkout is PHP templates and hooks; the block checkout is a React application talking to the Store API. Plugins that added fields, fees or payment UI through classic hooks need explicit block support.
WooCommerce keeps a compatibility list for the blocks. Check every payment, shipping and checkout-field plugin against it before switching.
Switch on a copy first
On staging, replace the shortcode with the Checkout block and walk every path: each payment method, each shipping method, coupons, account creation, custom fields. Look for things that are silently missing, not only errors.
Keep the shortcode page ready to restore. If a critical gateway is not supported yet, stay on the classic checkout — a working old checkout beats a modern broken one. See why WooCommerce checkouts stop working for what to look at if something fails.
After the switch
Watch orders by payment method for the first days: a method that disappeared shows up as zero orders for that method. Recheck after each plugin update, because block support is still actively changing.
A scheduled check that walks the block checkout to the payment step confirms the whole thing keeps working, whatever changes underneath it — the same idea as in how to monitor a WooCommerce checkout.
