Upgrading Kaspersky Security Center Linux through backup

To upgrade Administration Server from a previous version (starting from version 13) to version 15.1, you can create a backup of the Administration Server data and restore this data after installing Kaspersky Security Center Linux of a new version. If problems occur during installation, you can restore the previous version of Administration Server by using the backup of the Administration Server data created before the upgrade.

To upgrade an earlier version of Administration Server to version 15.1 through backup:

Before the upgrade, back up the Administration Server data with an older version of the application.
Uninstall the older version of Kaspersky Security Center Linux.
Install Kaspersky Security Center Linux version 15.1 on the former Administration Server.
Restore the Administration Server data from the backup created before the upgrade.
For devices on which the earlier version of Network Agent was installed, create and run the task for remote installation of the new Network Agent version.
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.
