I'm not a FortiSIEM engineer, but as far as I can see in internal documentation, there are plans to upgrade to CentOS 8.5 in place. For more information, you might want to open a Technical Support Ticket and get in touch with the FortiSIEM support team directly.
Hope that helps :)

Hey there JZ,I saw your post about FortiSIEM 6.3.3 and CentOS 8 EOL. I understand that you are wondering about getting new updates from Fortinet or migrating to a new OS.It sounds like Fortinet has plans to upgrade to CentOS 8.5 in place, but it's not confirmed yet.Also, it's worth noting that if you're looking for alternative solutions, you might want to consider migrating to a different version of Linux. For example, CentOS 7 End of Life Extended Lifecycle Support. But it still can be used with Extended Lifecycle Support. You can check out the TuxCare website.
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
