IBM SA41-5155-05 Chapter 1. Overview of RISC-to-RISC Upgrades and Data Migrations

Chapter 1. Overview of RISC-to-RISC Upgrades and DataMigrations

The road map lists important considerations and activities that are critical to the

successful model upgrade of a system. Although this road map is not designed to

be an all inclusive how-to source for activities relating to upgrading your system, it

covers the essentials by guiding you to the proper source. Follow all the steps in

the order presented and notify your IBM

representative for assistance if you run

into difficulties.

This road map also covers how to perform a model to model data migration. A

data migration can be performed from almost any iSeries 400 model to any model.

The source model must be at the same release as the new model to correctly

complete the data migration. Data migration involves a new system with a new

serial number.

For an overview of the RISC-to-RISC upgrades and data migration, refer to

“Upgrade process flow”on page2 and the “Data migration process flow”on

page4.

This road map covers the following RISC-to-RISC upgrades:

Note: The current system may require hardwareupgrades or configuration

changes to satisfy capacity and compatibility requirements of new software

and hardware.

vIBM AS/400 Model 170 to IBM AS/400 Model 170

There are no upgrades into or out of a Model 170. The Data Migration section of

this book covers the procedure used to perform a data move from the source

system to the new iSeries model.

vIBM ~iSeries Model 270 to IBM ~iSeries Model 270

There are no upgrades into or out of a Model 270. The Data Migration section of

this book covers the procedure used to perform a data move from the source

system to the new iSeries model.

vIBM AS/400 Models 5xx to IBM AS/400 Models 7xx

vIBM AS/400 Models 6xx to IBM AS/400 Models 7xx

vIBM AS/400 Models 7xx to IBM AS/400 Models 7xx

vIBM AS/400 Models Sxx or IBM AS/400 Models 5xx to IBM ~iSeries

Models 8xx

There are no model upgrades into a Model 8xx from a Model 5xx, 6xx, Sxx, or

SBx. However, some hardwaremay be moved from the 5xx into a migration I

expansion unit (I/O and disk unit). The Data Migration section of this book

covers the procedure used to perform a data move from the source system to the

new iSeries 400 model.

vIBM AS/400 Models 6xx to IBM ~iSeries Models 8xx

vIBM AS/400 Models 7xx to IBM ~iSeries Models 8xx

vIBM ~iSeries Models 8xx to IBM ~iSeries Models 8xx
