Updating the application

This section contains a step-by-step description of the Kaspersky MLAD update procedure.

Updating Kaspersky MLAD is possible starting with application version 4.0.1-001. When Kaspersky MLAD is updated, all of the following data that was uploaded, received, or processed by the previous version of Kaspersky MLAD will be saved: tag configurations, presets, ML models, and settings of Kaspersky MLAD.

Only the software specified in the hardware and software requirements should be installed on the Kaspersky MLAD server.

Kaspersky MLAD is updated to fix security flaws and application vulnerabilities or when new versions of the application are released under the current Technical Support Agreement. The application update is performed by a qualified technical specialist of the Customer, a Kaspersky employee, or a certified integrator.

To update Kaspersky MLAD from the command line:

1. Unpack the archive named mlad-4.0.2-<new build number>.tar.xz that is included in the distribution kit:

   tar xf mlad-4.0.2-<new build number>.tar.xz

2. Navigate to the directory where you unpacked Kaspersky MLAD:

   cd mlad-4.0.2-<new build number>

3. Run the application update script named upgrade.sh:

   sudo ./upgrade.sh -u -f <full path to the release.txt file of the application assembly being updated>

   You can run the upgrade.sh script with the -h switch if you want to call up the assistant in the Kaspersky MLAD update interface:

   sudo ./upgrade.sh -h

4. Follow the instructions of the Application Upgrade Wizard.

Kaspersky MLAD will be updated to the version specified in the build number. All application files are located in the directory where Kaspersky MLAD is installed (mlad-release-4.0.2-<installation build number> by default). A directory named upgrade_backup-4.0.2-<previous build number> will also be created there and will contain a backup copy of the previous version of Kaspersky MLAD.

You can move the directory containing the backup copy of the application to another storage location in accordance with your company regulations.
