Example of system operations
The following figure shows an example of the system operations to output the configuration and definition information, and to migrate the system to a different host. The system used in this example as the source environment of migration, is set up in 4.1 System setup for improving machine performance by allocating Web Server to a different host.
Figure 4‒8: Example of the system operations to output configuration and definition information, and to migrate the system environment to other host The following table describes the settings used in the example.
