[ovirt-users] Re: Suggested upgrading path from CentOS based 4.4.8 to 4.4.9

Hi Gianluca, I have a self hosted platform with plain CentOS 8.4 host. Also my engine is currently running CentOS 8.4. I updated my whole system from 4.4.7 to 4.4.9. As 4.4.9 does not support CentOS hosts I had to migrate them to CentOS Stream 8 as well. Due to dependency issues I have put the host into maintenance mode and did the rest through CLI. # dnf swap centos-linux-repos centos-stream-repos # dnf update ovirt-release44 # dnf distro-sync # reboot Done

I did not change the engine OS aa CentOS 8.4 is still supported here. Also I did the update in multiple steps over a couple of days which did not cause any issue on my side. Hope this helps.
