> The current upgrade requires stopping all nodes at the same time, upgrading all nodes, and then restarting all nodes, which will interrupt the service.
> It is recommended to support rolling upgrades, each node is stopped, upgraded, and restarted one by one to avoid service interruption.
> Before all nodes are upgraded, the early version of the inter-connection protocol is adopted between nodes. When all nodes are upgraded, the inter-connection protocol will upgrade to the current version.
