@chunhui1012 If you use YurtAppSet to deploy applications across NodePools, you can use the tweaks feature in YurtAppSet to perform gray upgrade for applications.

the proposal of YurtAppSet is here: https://github.com/openyurtio/openyurt/blob/master/docs/proposals/20240102-upgrade-yurtappset-to-v1beta1.md
