To upgrade Administration Server from a previous version (starting from version 13) to version 14, you can install a new version over an earlier one by using the Kaspersky Security Center installation file.
To upgrade an earlier version of Administration Server to version 14 by using the installation file:
$ sudo rpm -Uvh --nodeps --force ksc64-<version number
>.x86_64.rpm
$ sudo dpkg -i ksc64_<version number
>_amd64.deb
After the command has been successfully executed, the /opt/kaspersky/ksc64/lib/bin/setup/postinstall.pl script is created. The message about that is displayed in the terminal.
Installation of the application on your device will continue after you have entered 'Y' twice.
The picture below shows the last two steps.
Accepting the terms of the EULA and the Privacy Policy, and selecting the standard Administration Server installation mode in the command-line terminal
Next, the script configures and finishes upgrading the Administration Server. During the upgrade, you cannot change the Administration Server settings adjusted before the upgrade.
We recommend that you upgrade the Network Agent for Linux to the same version as Kaspersky Security Center Linux.
After completion of the remote installation task, the Network Agent version is upgraded.
