Upgrading Central Node installed as a cluster

You can upgrade Central Node to version 6.1 only from version 6.0.2. If you are using an older version, you must upgrade Central Node to 6.1 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, 5.1 → 6.0, 6.0 → 6.0.2.

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 Central Node installed as a cluster:

1. Place the application upgrade package on the Central Node cluster server with the manager role in the Docker swarm, in the /data directory. To view the role, use the $ docker node ls command.
2. Enter the management console of the relevant server over SSH or through a 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 6.1 on an Ubuntu operating system, run the following command: tar xvf /data/kata-cn-ubuntu-upgrade-6.1.0-324-x86_64_en-ru-zh.tar.gz -C /data/.
   • If you are upgrading the application to version 6.1 on an Astra Linux operating system, run the following command: tar xvf /data/kata-cn-astra-upgrade-6.1.0-324-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

   This opens the user name entry window.

6. In the Username field, enter the name of the user with administrator rights, select the OK button and press Enter.

   Default value: admin.

7. In the Password field, enter the password of the user with administrator rights, select the OK button, and press Enter.

   This opens the window for entering the path to the update archive.

8. In the Data directory field, enter the path to the update archive, select the OK button, and press Enter.

   Default value: /data/upgrade.

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

9. Connect to the server that you want to power off over SSH or through a terminal.
10. Run the poweroff command.
11. Mount the iso image of Kaspersky Anti Targeted Attack Platform version 6.1. If you are using Kaspersky Anti Targeted Attack Platform based on the Astra Linux operating system, follow these instructions to create an iso image.
12. Boot from the device that has the mounted iso image.
13. In the GRUB menu, select Upgrade KATA 6.0.
14. Follow the remaining steps of the wizard to complete the upgrade on the server.
15. 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.

16. Repeat steps 9 to 15 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 15 is omitted.

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.
