4.4.1 Migrating the system environment to a different host

Migration of the system environment enables you to curtail the time required for setting up and operating the system in other environments.

• 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.

  Table 4‒24: Settings used in the example (migrating system environment)

  Classification		Item	Example of settings
  Entire system		Name of the Easy Setup definition file to output the migration information	MyWebSystemexport.xml
  Source environment	Host for allocating the Web server	Host name	apsv1
  		IP address (management IP address)#1	192.168.100.11
  	Host for allocating the J2EE server#2	Host name	apsv2
  		IP address (management IP address)#1	192.168.100.12
  Target environment	Host for allocating the Web server	Host name	apsva
  		IP address (management IP address)#1	192.168.100.21
  	Host for allocating the J2EE server#2	Host name	apsvb
  		IP address (management IP address)#1	192.168.100.22

  #1

  If the network has single configuration, the IP address serves as both the business IP address and the management IP address.

  #2

  Allocate the Management functionality (Management Server) to the host for allocating the J2EE server.

• Tasks to be executed and necessity of the tasks

  The following table describes the tasks to be executed for migrating the system environment and the necessity of these tasks. Use Smart Composer functionality to migrate the system environment.

  Table 4‒25: Tasks to be executed for migrating the system environment and necessity of the tasks (when using Smart Composer functionality)

  Tasks to be executed for migrating the system environment	Necessity of the tasks	Conditions for executing the tasks	References
  Setting up the source system environment	Y	Mandatory	4.1
  Preparing the host in the target environment	Y	Mandatory	4.4.2(1)
  Output of the configuration and definition information	Y	Mandatory	4.4.2(2)
  Setting up the target system environment	Y	Mandatory	4.4.2(3)

  Legend:

  Y: Mandatory task.
