You must perform all upgrades as the root user. You can only upgrade to the
latest version of PureMessage from a supported version of
PureMessage. "For information about currently supported
versions, see the "PureMessage Versions and Platform
PureMessage includes a menu-based installer that
streamlines the upgrade process. This installer launches in a console window. The window is
partitioned into two sections; the left side displays installation/upgrade options, and the right
side displays help text. Use the following keyboard commands to navigate the installer:
: moves cursor from one option to another
: shifts focus between the left and right panes of the installer
: scrolls the text in the right pane of the installer (if the right pane has
: selects the highlighted option or check box(es)
: accepts the selected options or check box(es)
Sophos strongly recommends
that you do not resize the installer console window once it launches. Resizing the console window
may cause the installer to terminate.
Use the Upgrade PureMessage
Components option in the PureMessage
installer to check for PureMessage updates, download the
updates, and install the updates.
During upgrades, PureMessage
automatically adjusts the PostgreSQL database in an attempt to improve performance. If the
adjustments are successful, PureMessage displays a
confirmation message. If the adjustments fail, it is likely due to the shared memory
configuration of your system. PureMessage will revert the
changes and create a postgresql.conf.recommended
file that contains
appropriate system settings. For more information, see "Tuning PostgreSQL for PureMessage"
in the Sophos Knowledgebase.
