how to isolate the cluster when application is upgraded on it
Two physical servers construct one cell. And each physical servers has one cluster, and each cluster has one http server node and 2 vertical WAS nodes. Load balancer sends request to each cluster (so totally 2 clusters in 1 cell).
Now we want to deploy one new version of application on cluster A, but the old version of that application is still on Cluster B. (Because this new version application will be test before it is deployed to cluster B)
How to isolate the cluster A before deploy the new version of application, so that no new request goes to clusterA during the deployment?
Your any idea will be great appciated.

I would just remove the node from the cluster, apply your application and test it, and then re-federate it.
