Hardware Investment for Upgrading
Youmay choose to upgrade your existing RISC system processor, or replace it with
a new iSeries 400 model. In either case, you may keep most of the current system.
The process of either an upgrade of your existing system or moving parts from an
existing system to a new system, are called miscellaneous equipment specification
(MES). MES denotes the process steps of an upgrade. The type of MES depends on
several factors:
vYourcurrent processor model
vCosts
vYoursystem availability requirements
The information in this book will help to determine the right path to an upgrade.
This is based on the current model and the goals of the process.
How Long will the Upgrade Take?
The upgrade process includes planning, ordering, shipping, installing and testing
the system. The following table shows approximately how long an upgrade might
take.
Note: Youshould plan at least one additional hour of down time to load the
operating system for systems not preloaded.
Order Planning - 5 to 15
Days
Installation Planning and Preparation - 10 to 30 days Phase II Installation - Weekend
(1 to 3 days)
Phase I Installation - 5 to
20 Days

What is a Data Migration?
A data migration is the process of moving the OS/400
®
and the data from one
model iSeries 400 or AS/400 to a new model iSeries 400 AS/400.
The source system must be at the same release level as the target server.This
includes OS/400, all objects, and all licensed programs.
For customers ordering a new RISC iSeries 400 server with V4R4 or V4R5 to
replace an existing RISC iSeries 400 or AS/400 model (″source″) and needing to
migrate their data from the ″source″model to the new server,a new feature code
Feature Code (F/C) #0205, is now available. This new feature code should be
ordered against the new RISC iSeries 400 server.It is valid on orders for all new
servers except the Models 150 and SB1.
