[ovirt-users] Mixing OS versions

Greetings, We've been using Scientific Linux 7 quite successfully with oVirt for years now. However, since there will not be a SL7 we are transitioning new servers to CentOS8. I would like to add a new oVirt hypervisor node. How bad of an idea is it to have a 8 system when the rest are 7 even though the version of oVirt will be the same? Thanks!
