WooCommerce has published pre-release information for version 11.0. Pre-release documentation is valuable because it gives stores and extension developers time to test; it is not a reason to apply a beta release to a revenue-critical production site.
Read WooCommerce’s 11.0 pre-release notes.
Start with an inventory of dependencies
List the active theme, checkout customizations, payment gateways, subscription logic, shipping extensions and reporting integrations. Mark which ones are business-critical and which have a known tested version.
Run a staged test matrix
Clone production to staging, update in a controlled order and run representative orders. Include guest checkout, refunds, coupons, tax calculation, shipping variations, logged-in accounts and transactional emails. Record failures with enough detail for an extension vendor to reproduce.
Compatibility preparation is routine operational work. Doing it before the release reaches your normal update queue is the low-risk path.
