Distributed architecture deployment updates
If you are using a distributed architecture deployment, the 9.1.1 installation retains the product version as 9.1.1.0.
All nodes in a cluster must be upgraded to the same version; otherwise nodes will not be available.
To uppgrade the nodes
-
Stop all services on all nodes.
-
Install 9.1.1 on the Master node first.
-
Continue to install 9.1.1 on all other nodes in the cluster.
