About upgrading Kaspersky Security Center

This section contains information on how to upgrade Kaspersky Security Center from a previous version. You can upgrade Kaspersky Security Center in different ways, depending on whether Kaspersky Security Center was installed locally or on the Kaspersky Security Center failover cluster nodes.

During the upgrade, concurrent use of the DBMS by Administration Server and another application is strictly forbidden.

When you upgrade Kaspersky Security Center from a previous version, all the installed plug-ins of supported Kaspersky applications are kept. The Administration Server plug-in and Network Agent plug-in are upgraded automatically (both for the Administration Console and Kaspersky Security Center Web Console).

Upgrading Kaspersky Security Center from a previous version

The following topic describes recommended preparation steps for the upgrade: Upgrading Kaspersky Security Center and managed security applications.

You can install version 14 of Administration Server on a device that has an earlier version of Administration Server installed (starting from version 11 (11.0.0.1131b)). When upgrading to version 14, all data and settings from the previous version of Administration Server are preserved.

If problems occur during Administration Server installation, you can restore the previous version of Administration Server using the backup copy of the Administration Server data created before the upgrade.

If at least one Administration Server of the new version has been installed on the network, you can upgrade other Administration Servers on the network using the remote installation task that uses the Administration Server installation package.

If you deployed the Kaspersky Security Center failover cluster, you can also upgrade Kaspersky Security Center on its nodes.

To upgrade an earlier version of Administration Server to version 14:

1. Run the ksc_14_<build number>_full_<language>.exe installation file for version 14 (you can download this file from the Kaspersky website).
2. In the window that opens, click the Install Kaspersky Security Center 14 link to start the Administration Server Setup Wizard. Follow the instructions of the Wizard.
3. Read the License Agreement and Privacy Policy. If you agree with all the terms of the License Agreement and the Privacy Policy, select the following check boxes in the I confirm I have fully read, understood, and accept the following section:
   • The terms and conditions of this EULA
   • Privacy Policy describing the handling of data

   Installation of the application on your device will continue after you select both check boxes. The Setup Wizard prompts you to create a backup of the Administration Server data for the earlier version.

   Kaspersky Security Center supports data recovery from a backup created with an older version of Administration Server.

4. If you want to create a backup of the Administration Server data, specify this in the Administration Server backup window that opens.

   A backup is created by the klbackup utility. This utility is included in the distribution kit, and is located at the root of the Kaspersky Security Center installation folder.

5. Install Administration Server version 14 by following the Setup Wizard.

   If a message appears that the Kaspersky Security Center Web Console service is busy, click the Ignore button in the Wizard window.

   We recommend that you avoid terminating the Setup Wizard. If you cancel the upgrade at the step of Administration Server installation may cause the upgraded version of Kaspersky Security Center to fail.

6. For devices on which the earlier version of Network Agent was installed, create and run the task for remote installation of the new version of Network Agent.

   We recommend that you upgrade the Network Agent for Linux to the same version as Kaspersky Security Center.

   After completion of the remote installation task, the Network Agent version is upgraded.

Upgrading Kaspersky Security Center on the Kaspersky Security Center failover cluster nodes

You can install Administration Server version 14 on every Kaspersky Security Center failover cluster node where the Administration Server with an earlier version is installed (starting from version 13.2). When upgrading to version 14, all data and settings from the previous version of Administration Server are preserved.

If you previously installed Kaspersky Security Center on devices locally, you can also upgrade Kaspersky Security Center on these devices.

To upgrade Kaspersky Security Center on the Kaspersky Security Center failover cluster nodes:

1. Stop the cluster.
2. Perform the following actions on the active node of the cluster:
   1. Run the ksc_14_<build number>_full_<language>.exe executable file.

      A window opens and prompts you to select the Kaspersky applications to upgrade. In the application selection window, click the Install Kaspersky Security Center 14 Administration Server link to start the Administration Server Setup Wizard. Follow the instructions of the Wizard.

   2. Read the License Agreement and Privacy Policy. If you agree with all the terms of the License Agreement and the Privacy Policy, select the following check boxes in the I confirm I have fully read, understood, and accept the following section:
      • The terms and conditions of this EULA
      • Privacy Policy describing the handling of data

      Installation of the application on your device will continue after you select both check boxes.

      If you do not accept the License Agreement or Privacy Policy, click the Cancel button to cancel the upgrade.

3. Perform the same actions on the passive node of the Kaspersky Security Center failover cluster as on the active node.
4. Start the cluster.

As a result, you installed the Administration Server of the latest version on the Kaspersky Security Center failover cluster nodes.
