Completing the migration

 

To migrate data to the target system or partition, perform these procedures. Be sure you have completed the necessary preparation before you begin.

  1. Perform the steps in Appendix D: "Recovering your server to a different server" of the Backup and Recovery Guide. If a controller or device no longer has a valid resource on the system, follow the steps in fix hardware resource names after an upgrade to make the necessary corrections.

  2. Install any new licensed programs (LPs).

  3. Print your system configuration information as follows:

    1. On the i5/OS® command line, enter PRTSYSINF and then print the resulting spooled file. This prints reports of the hardware resources, software resources, system values, installed fixes (program temporary fixes or PTFs), and other configuration information.

    2. Print a new system configuration list and keep this list for future reference.

    3. On the i5/OS command line, enter WRKDEVD. Use option 6 to print the device descriptions.

    4. On the i5/OS command line, enter WRKCTLD. Use option 6 to print the controller descriptions.

    5. If you have a partitioned system, print the system configuration for logical partitions.

  4. Save the entire system using option 21 of the GO SAVE command. Make sure that you specify the following options:

    1. Vary off the network server...*ALL

    2. Unmount file systems..........Y

    IBM recommends that you have two copies of the backup media.

  5. Resume normal operations and verify that all your applications run properly.

  6. Tune the system performance.

    This ensures that your systems make the best use of the system resources and allows workloads to run as efficiently as possible.
