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:
- Open the operating system console.
- Update all packages and libraries of the CentOS Linux 8 operating system. To do so, enter the following command:
sudo dnf update
- 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
- Change the default repository to the CentOS Stream repository. To do so, enter the following command:
sudo dnf swap centos-{linux,stream}-repos
- Synchronize the installed packages and libraries from the new default repository. To do so, enter the following command:
sudo dnf distro-sync
- Restart the operating system. To do so, enter the following command:
sudo reboot
