Migrating CentOS Linux 8 to CentOS Stream 8

At the end of 2021, Red Hat® is discontinuing support for the CentOS Linux 8 operating system. This means that security updates will no longer be released for CentOS Linux 8 in 2022. In other words, computers and applications running CentOS Linux 8 (including Kaspersky Industrial CyberSecurity for Networks) will not be fully protected against new types of threats and attack techniques.

Red Hat is advising CentOS Linux 8 users to migrate to the CentOS Stream 8 operating system. Kaspersky Industrial CyberSecurity for Networks is compatible with CentOS Stream 8.

You can migrate CentOS Linux 8 to CentOS Stream 8 either before or after installation of Kaspersky Industrial CyberSecurity for Networks components. Migration of the operating system is performed locally on each computer where a Kaspersky Industrial CyberSecurity for Networks component is installed or will be installed.

To migrate CentOS Linux 8 to CentOS Stream 8:

1. Open the operating system console.
2. Update all packages and libraries of the CentOS Linux 8 operating system. To do so, enter the following command:

   sudo dnf update

3. Install the centos-release-stream package for access to CentOS Stream repositories. To do so, enter the following command:

   sudo dnf install centos-release-stream

4. Change the default repository to the CentOS Stream repository. To do so, enter the following command:

   sudo dnf swap centos-{linux,stream}-repos

5. Synchronize the installed packages and libraries from the new default repository. To do so, enter the following command:

   sudo dnf distro-sync

6. Restart the operating system. To do so, enter the following command:

   sudo reboot
