No. If you already upgraded to 3.6, your database is incompatible with 3.5. You might try exporting all your VMs to an export domain, setup 3.5, import back. Not even sure this works - i.e. that 3.6 export domains are 3.5 compatible. Why do you want to do this? Best, -- Didi

See in release notes http://www.ovirt.org/release/3.6.6/ BZ 1241149 [RFE] Provide way to preform in-cluster upgrade of hosts from el6->el7. https://bugzilla.redhat.com/show_bug.cgi?id=1241149 or not?
