Use CasTool.exe to change a child server�s parent server. The tool allows you to unregister a child server from a parent server and register it to another parent server.
The action to register or unregister child servers does not generate the same result as to enable or disable child servers. The former permanently cuts the parent and child server connection, while the latter temporarily suspends the connection by maintaining the heartbeat connection between two servers.
For example, if you registered child server xyz to parent server a, run CasTool.exe to unregister xyz from a and register it to parent server b. Parent server b manages xyz. a's cascading structure tree removes xyz from the list.
CasTool.exe is useful when you want to balance the server load between servers a and b. These are the common scenarios:
Parent server a is managing more child servers than parent server b
Parent server a becomes overloaded and you want to reduce the load and transfer some child servers to parent server b
