For upgrade from NSX 3.2.0, or 3.2.0.1, the upgrade should be initiated from the orchestrator node.
For upgrade from NSX 3.2.1.x and later, the upgrade can be initiated from any NSX manager node.
To identify the orchestrator node, execute the command "get service install-upgrade" from admin CLI on any one of the NSX Managers, the "Enabled on" field identifies the orchestrator node.
