Upgrading the Central Node component installed as a cluster

You can upgrade the component to version 6.0 only from version 5.1. If you are using an older version, you must upgrade it to 6.0 in the following order: 3.7 → 3.7.1, 3.7.1 → 3.7.2, 3.7.2 → 4.0, 4.0 → 4.1, 4.1 → 5.0, 5.0 → 5.1.

If you are using the distributed solution and multitenancy mode, you must prepare the PCN and SCN servers as well as standalone servers with the Sensor component for the upgrade. For more details on the preparation procedure, see the Updating Kaspersky Anti Targeted Attack Platform section.

The upgrade is delivered as an upgrade package. The package is included in the application distribution kit.

To upgrade the Central Node component installed as a cluster:

  1. Place the application upgrade package on any server of the cluster with the Central Node component in the /data directory.
  2. Sign in to the management console of the Central Node server where you want to upgrade the component via SSH or through the terminal.
  3. Make sure that the /dev/sda2 file system on each server of the cluster has more than 100 GB of free space.
  4. Unpack the update archive:
    • If you are upgrading the application to version 6.0 on an Ubuntu operating system, run the following command: tar xvf /data/kata-cn-ubuntu-upgrade-6.0.0-200-x86_64_en-ru.tar.gz -C /data/.
    • If you are upgrading the application to version 6.0 on an Astra Linux operating system, run the following command: tar xvf /data/kata-cn-astra-upgrade-6.0.0-200-x86_64_en-ru.tar.gz -C /data/.
  5. Install the upgrade package by running the following commands:

    cd /data/upgrade/

    chmod +x ./install_kata_upgrade.sh

    ./install_kata_upgrade.sh

  6. Install the upgrade by running the following commands:

    source /tmp/upgrade-venv/venv/bin/activate

    kata-upgrade --data-dir /data/upgrade/ --password <password of the 'admin' user>.

    If the password contains special characters, the password variable must be specified in the following format: --password '<password>'.

    After some time, the console displays a message telling you to power off one of the servers in the cluster.

  7. Connect to the server that you want to power off over SSH or through a terminal.
  8. Run the poweroff command.
  9. Mount the iso image of Kaspersky Anti Targeted Attack Platform version 6.0. If you are using Kaspersky Anti Targeted Attack Platform based on the Astra Linux operating system, follow these instructions to create an iso image.
  10. Boot from the device that has the mounted iso image.
  11. In the GRUB menu, select Upgrade KATA 5.1.
  12. Follow the remaining steps of the wizard to complete the upgrade on the server.
  13. After the upgrade is complete, go to the console of the server you connected to at step 2 and press Enter.

    A script is started that completes the upgrade process. After the update is complete, the console displays a message telling you to shut down the next server in the cluster.

  14. Repeat steps 7 to 13 for each server in the cluster.

    The last server to be updated is the server to which you connected at step 2. For that server, step 13 is omitted.

  15. Install the application upgrade package to version 6.0.2

    If you are upgrading the application from version 6.0, you do not need to install the version 6.0.1 upgrade package.

The Central Node component is upgraded.

After updating the component, you must log in again to the Central Node server management console over SSH or through the terminal.
