After switching SAP NetWeaver 2004 or SAP NetWeaver 7.0 with the SwitchTool to the SAP JVM 4.1 all the configured server nodes will have the same parameters as set for server0.Server individual parameters and values are lost after the switch.
E.g. the individual configured Wily Introscope Agent names per server node used for monitoring or alerts are overwritten by the SwitchTool with the server0 values.
The Wily Introscope Agent name will be retained for each server node with Patch Level 5 of the SwitchTool.
With older SwitchTool patch levels you have to reconfigure server specific parameters and values, like the agent names, manually after the switch. The agents are still usable and they are working. Wily will automatically add a %<n> to the agent name in case there is already an agent with the same name registered.
