This is where you load the new operating system.

__ 7. See the manual Software Installation, SC41-5120-05 to install software (for example, Licensed Internal Code, operating system, PTFs, etc.). Install software for the required and desired partitions. A PDF version of this manual is available from the iSeries Information Center under System planning and installation -> Hardware and software -> Software and licensed programs -> Install software.

Important: If you are using logical partitions, update all your partitions to V5R1, if needed.

__ 8. Delete any unused device configuration descriptions (delete unused line, line descriptions, and non-reporting resources).

Important: To delete line and device and descriptions, use the WRKLIND and WRKDEVD commands and verify that all the descriptions listed are in use. If you are sure one is not, you should delete it. If you are not sure, you should leave it.

__ 9. Before proceeding with the next step, make that sure during step 7, you obtained or performed the following:

a.OS/400 is current (You determined whether you needed to replace software and replaced Licensed Internal Code, operating system, and licensed programs if needed.)

b.PTFs are current

c.Saved your current system (recommended as recovery data in case of disaster)

__ 10. If you do not have a current system backup that allows you to recover in case of disaster, save the entire system on each partition. Make sure that you save the system and data on a tape unit that is compatible with the tape unit on the target system. To save the system, use option 21 on the Save menu. For more information about saving the entire system using option 21, refer to any of the following:
