"RHEV 3.5 supports both RHEL6 and RHEL7 hosts (RHEL or RHEV-H). It is recommended to upgrade your hosts to RHEL7 once on RHEV 3.5." If this is true i could make an update of the hypervisors 6 and not a reinstall with centos 7 to reach the 3.5 release...After this as you suggest i can do a storage domain detach from 3.5 in order to attach to a new 4.3 enviroment... _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4IAJAAGPZSKLC3R6XGOD7KPFZ4MEDPJO/
