Pega 8.5.1 upgrade - "StreamServiceException: Kafka data belongs to a node pega-stream-0 from the different cluster"


1. Is the parameter, prconfig/cloud/isNodeAgnosticAdminStudio, only applicable to the web pods? Do you suggest that we use this parameter in our Openshift cluster running PEGA 8.5.1?

2. We faced issue with bring-up of stream pods after upgrade from 8.4.0 to 8.5.1 (on Openshift cluster). Do you have any suggestions on how to prevent the below exception from occurring during a production upgrade?

Workaround - After removing /opt/pega/kafkadata/prpc_node_id during stream pod startup, the pods are coming up. Would putting the 8.4 stream pods in Quiesce before scale-down, help to prevent this error from occurring after a in-place upgrade?

Cannot start service [StreamServer.Default]. Will retry in 180 seconds. Remaining attempts: 1][STACK][com.pega.dsm.dnode.api.StreamServiceException: Kafka data  belongs to a node pega-stream-0 from the different cluster 631a648e-9867-48bd-a00d-1c8ffd9d35d1
