As of December 31, 2021, support for the CentOS Linux 8 operating system has ended. So this means that the operating system will no longer receive software and security updates and if you continue to use this operating system, your system may become vulnerable to attacks over time.
CentOS Linux is a GNU/Linux distribution built using and compatible with the sources of the commercial Red Hat Enterprise Linux operating system. The CentOS Linux 8 release was made available just two years ago, on September 24, 2019, and was originally supposed to be supported for 10 years, until 2029.
However, Red Hat announced on December 8, 2020 that it will end the CentOS 8 series and focus its development on a new development platform called CentOS Stream. As stated by Red Hat and quoted by 9to5Linux, CentOS Stream is not an alternative to CentOS Linux 8 or any other supported CentOS Linux series. So it’s time to switch to an alternative free operating system like Rocky Linux or AlmaLinux OS.
Both Rocky Linux and AlmaLinux OS are great open-source, enterprise-ready and server-focused alternatives to CentOS 8. But before you decide which is best for your machines, we recommend that you make sure you have backups of your important files.
To migrate from CentOS 8 to Rocky Linux, you can use the free tool migrate2rocky by following the migration instructions provided by the Rocky Linux development team on this page. You can use the free tool almalinux-deploy to migrate from CentOS 8 to AlmaLinux OS. Both distributions offer full CentOS 8 support, among many other extra features not found in the CentOS 8 operating system lineup.
