Upgrading to a more recent version

New versions of ESET Mail Security are issued to implement improvements or fix issues that cannot be resolved by automatic updates to program modules.

Which product version is currently installed?

To determine the product version of ESET Mail Security, you have two options:

1.In Web interface, navigate to Home > Product version. To determine whether a new version of ESET Mail Security is available, click Check for new version.

2.Run an ESET command-line program with the --version parameter.

How to upgrade?

To upgrade to a more recent version, run an OS-related installation package as described in the Installation section. All parameters from the ESETS configuration file are set automatically under normal circumstances during the upgrade.

Important: ESET Mail Security 4.5.x uses a new anti-spam engine that cannot accept anti-spam settings from versions 4.0.x and earlier; attempts to merge settings will fail. We recommend that you make a backup of spamcatcher.conf and then migrate the settings into the ESETS configuration file manually.
