[ovirt-users] Re: Upgrade ovirt from 3.4 to 4.3

I think the alternative exporting the storage domain is perfect. Can you confirm that i have to reinstall the Hypervisors 3.4 (based on centos 6) to reach the 3.5? On the upgrade helper (3.4 to 3.5 ) i have found this " Upgrade hosts to 3.5. Reinstall with RHEL7 based hosts. Follow this solution: https://access.redhat.com/articles/1390733 Directly upgrading RHEV hosts from RHEL/RHEV-H 6 to RHEL/RHEV-H 7 is not supported: https://access.redhat.com/solutions/2752051 Change Compatibility Level (CL) of the cluster(s) and the Data Center to 3.5:" Thanks Luigi
