6 Upgrading from previous FSE releases

In this chapter, you will be instructed how to upgrade an FSE implementation that currently uses a previous FSE product version to release version 3.4. Upgrading will add the new functionality that has been implemented in the new FSE release, and install the FSE utilities: HSM Health Monitor and Log Analyzer. The upgrade procedure will preserve the current state of the FSE implementation, including its configuration, all migrated data on FSE media, a complete state of all HSM file systems and FSE databases and system files.

For a list of previous FSE products that can be upgraded to the new release, see the FSE release notes, chapter ”Supported hardware and software”, section ”Supported upgrade paths”.

Prerequisites

Before starting with upgrade, ensure that the following prerequisites are fulfilled:

A previous version of the FSE product is installed that can be upgraded with the current FSE version.

For information on which previous FSE products can be upgraded, see the FSE release notes, chapter Supported hardware and software”, section ”Supported upgrade paths”.

The required versions of the third-party software packages are installed on the system.

For information on how to upgrade or install the third-party software packages, see the third-party software documentation and the operating system documentation.

Make sure that you also have the following available:

• FSE installation guide for Windows

This is required, since while upgrading, you may also need to follow instructions provided in the above manual, depending on the platforms on other systems that are included in your FSE implementation.

Additionally, make sure you have the following available, depending on the Linux distributions installed on the Linux FSE hosts:

SUSE Linux Enterprise Server 9 documentation

Red Hat Enterprise Linux 4 documentation

This is required for correct operating system upgrade on these hosts.

You must be logged on to the system as root in order to execute shell commands.

Upgrade overview

To upgrade an FSE system, perform the following procedure. Most of the steps from the procedure are described in detail in the sections that follow:

1.If the FSE Management Console is installed in the FSE implementation, stop the FSE Management Console server and the FSE Management Console client processes.
