> Hi!
> During standard upgrade of NiFi from version 2.6 to 2.7.0 and later on 2.7.1
> we've faced an issue with cluster - using embeded zookeeper.
> After turning on NiFi cluster couldn't synchronize due to the differences in
> the flow.
> Flow.json.gz has been removed from 2 hosts (3 in the cluster).
> Also flow couldn't be synchronized. The only error which we get in the
> nifi-app.log is:
> {code:java}
> 2025-12-15 09:48:41,645 INFO [Process Cluster Protocol Request-45]
> o.a.n.c.c.node.NodeClusterCoordinator Status of XXXXX:8443 changed from
> NodeConnectionStatus[nodeId=XXXXXX:8443, state=DISCONNECTED, Disconnect
> Code=Node's Flow did not Match Cluster Flow, Disconnect
> Reason=org.apache.nifi.controller.serialization.FlowSynchronizationException:
> Failed to connect node to cluster because local flow controller partially
> updated. Administrator should disconnect node and review flow for
> corruption., updateId=44] to NodeConnectionStatus[nodeId=XXXXX:8443,
