> Key: NIFI-11162
> URL: https://issues.apache.org/jira/browse/NIFI-11162
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.20.0
> Reporter: macdoor615
> Priority: Major
> Fix For: 2.0.0
>
>
> 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.
