HP XC System Software Administration Guide Version 3.1

Software Upgrade
During a software upgrade, the HP XC System Software defers to the Linux rpm software, which has the
responsibility for ensuring the preservation of any Linux configuration files you have customized. For
more information, see rpm(8).
1.5.2 Configuration Files
Configuration files comprise the configuration files for the HP XC System Software and the configuration
files for integrated third-party software
For more information on these configuration files, see “HP XC Configuration Files” (page 36).
Reconfiguration
During reconfiguration, changes you made to all HP XC configuration files are preserved if you modified
the data according to the procedures in the HP XC documentation set.
For example, if you change the syslog-ng configuration information, (perhaps, filters or ports) you must
modify both the syslog-ng.conf and the syslog-ng template files so that the changes persist after a
reconfiguration.
Software Upgrade
During a software upgrade, customizations to the HP XC configuration files are preserved but might need
to be merged back into the configuration files.
HP XC preserves configuration files using standard RPM methods. The rpm upgrade process preserves
customizations by saving a copy of the old or new configuration file with either the .rpmsave or .rpmnew
suffix. To retain your changes, you must manually merge the saved customizations into the new
configuration file as documented in the upgrade and patch documentation.
