– The upgrade happens to both the hardware and software in the same process.
Note: You must upgrade hardware and software at the same
time when upgrading from CISC to RISC. This is unique
to CISC to RISC upgrades.
– Having the central site upgrade to PowerPC Technology and V4R3 or above, but having the target
sites remain at a previous release level with existing hardware.
You must be running on PowerPC AS hardware to create media for a target site system that you
upgrade to PowerPC Technology. See Upgrading a target site system to PowerPC Technology for
more details.
v Target site system. This system depends on the central site system for distribution of licensed
programs. This system is possibly unattended, and is probably not licensed to receive licensed program
media from IBM.
A target site system can be one of the following:
– Part of a distributed systems communications network.
– Operate independently of the central site system but rely on the central site for licensed program
distributions and application development and maintenance.
The distribution tasks should occur at the following times:
1. The initial distribution by the central site system
2. The distribution of fixes between releases
3. The distribution of an upgrade for IBM-supplied licensed programs
There are a number of terms, concepts, and choices you should become know about. Understanding the
following topics will help in the planning stage of the Central Site Distribution process.
v Distribution methods and the process flow
This details the two distribution methods at your disposal. The flow of each process, either media (tape
or DVD) or premastered CD-ROMs, is shown.
v Electronic distribution and installation of licensed programs
This tells about options for distributing IBM licensed programs and customer applications electronically
from a central site system.
v Total system package option or preloaded system option
When you choose the total system package option or the preloaded system option for ordering a new
system, the system will come with licensed programs installed and configured hardware.
v Release-level interoperability
The central site system and the target site have compatable software releases. Interoperability is the
ability of one system to exchange data or objects with another system.
v Fix (PTF) level
Fixes are available to update licensed program code between releases. It is important that both the
central site system and target site system be at the current fix level.
Upgrading a Target Site System to PowerPC Technology
You must be running on PowerPC AS hardware to create media for a target site system that you upgrade
to PowerPC Technology.
When you upgrade a target site system to an iSeries server with PowerPC Technology, you upgrade the
hardware and software at the same time.
Note: Systems that are running the V3R7 or Version 4 operating systems are already using PowerPC AS
software. This topic does not apply to such systems.
