This section describes how to upgrade Kaspersky CyberTrace on Windows from version 3.1 to 4.0.1, and from 4.0 to 4.0.1.
The instruction below applies to installations done by using the executable installer.
To upgrade Kaspersky CyberTrace automatically to a newer version:
If Feed Service is stopped and the upgrade continues, all the settings, user accounts data, available feeds, and certificates will be automatically transferred to the new version.
After the upgrade process is finished, the actionable fields are not specified for new feeds that were not supported in the previous version. If needed, specify these fields manually on the Settings > Feeds tab.
When upgrading from version 3.1, make sure that /opt/kaspersky/ktfs/etc/kl_feed_service.conf contains only a single copy of the FalsePositive and InternalTI suppliers, with the corresponding standard names (Black_List.json and White_List.json). If not, the installer displays an error and exits.
After you finish the upgrade process, Feed Service will be launched automatically.
Note that automatic upgrade with the executable installer is available only if you have accepted the EULA in the installation that is being upgraded.
Actions in case of error during upgrade
The configuration files and some other files are moved to the $TEMP\cybertrace_old temporary directory during the upgrade after Feed Service stops. If errors occur during the upgrade, the moved files remain in the temporary directory. If you encountered an error during an automatic upgrade, contact your Technical Account Manager (TAM) for more information on solutions to the problem.
To determine the location of the $TEMP directory, the Kaspersky CyberTrace executable installer takes the first existing variable from the following list: %TMP%, %TEMP%, %USERPROFILE%, %WINDIR%. The executable installer tries to write to this directory. If an attempt to write fails, the executable installer writes to %WINDIR%\Temp.
