2.6  Upgrade and Uninstallation

Windows Operating Systems

To upgrade this product (i.e. to install a newer version of the product) the Kerio Administration Console must first be closed. The other components (Kerio MailServer Engine and Kerio MailServer Monitor) will be automatically closed by Kerio MailServer installation program. The installation program will detect the directory where the older version is installed and replace appropriate files with new ones automatically. All settings and all stored messages will be available in the new version. We recommend not changing the installation directory!

When upgrading Kerio MailServer, follow the same scheme as for the first installation of Kerio MailServer (see chapter 2.4  Installation).

Once the product is upgraded successfully, a backup of the configuration files of the previous Kerio MailServer version is saved in the directory where Kerio MailServer is installed (C:\Program Files\Kerio by default), under the UpgradeBackups directory.

Kerio MailServer can be uninstalled by using Uninstall from the Start menu using the Add/Remove Programs in the Control Panels:

  1. Under Add or remove programs, select Kerio MailServer and click on Remove.

  2. This runs the Microsoft Installer installation wizard.

  3. In the first dialog, it is possible to choose whether Kerio MailServer will be removed completely, including the data store and configuration files (see figure 2.5  Removal of the data store and configuration files):

    Removal of the data store and configuration files

    • Remove configuration files — if this option is enabled, configuration files (mailserver.cfg and users.cfg) as well as the license file, SSL certificates, statistics and logs will be removed.

    When sure that the settings are finished, continue by clicking on the Next button.

  4. Progress of the uninstallation process is showed on the status bar. Please be patient, the process may take several minutes.
