The upgrade procedure described in this chapter assumes the
following:
Your existing InterChange Server (ICS) installation must be one
of the following versions:
WebSphere InterChange Server version 4.1.1
WebSphere InterChange Server version 4.2.0
WebSphere InterChange Server version 4.2.1
WebSphere InterChange Server version 4.2.2
Important:
If you have an earlier version of ICS (before version 4.1.1),
you must consult IBM technical support for assistance. Do
not attempt to follow the upgrade process described in this
chapter.
You will perform the upgrade to the current version of InterChange Server
in a development environment, then move the upgrades to your production
environment after system tests have been completed.
You have all appropriate software available. For a list of required
software, see Software requirements. It is also important that all operating systems are
upgraded to the correct version and patch or fixpack level.
You will perform the upgrade to InterChange Server (on the UNIX machine)
as well as to the WebSphere Business Integration Toolset (on the Windows
machine). This chapter provides instructions for the upgrade to
InterChange Server. It also summarizes upgrade steps needed for the
WebSphere Business Integration Toolset. However, because WebSphere
Business Integration Toolset is on a Windows machine, you should refer to the
upgrade information in the System Installation Guide for Windows
for detailed upgrade instructions for this Toolset.

If you are upgrading in a high-availability environment, you must perform
all of the upgrade steps in this chapter to each machine in the
cluster.
