[ovirt-users] Downgrade ovirt-engine 3.6 to 3.5

[Sandvik Agustin]

Hi,

thanks for the quick reply, i have export domain already running and
attached to ovirt 3.6.

co'z i have 3 hypervisor, 2 are running centos 6.7, 1 is running centos 7,
i don't have any problem at this moment, but i want them to be in the same
cluster, the 2 centos 6.7 are in the same cluster but i'm unable to add the
host running centos 7 on that cluster, so what i did is create another
cluster and add this host centos 7 on the new cluster.

I just want them 3 host in the same cluster. :)

TIA
