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”.

• 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

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