Re: [ovirt-users] Upgrade path from running 3.6 (centos 7) to 4.1
A Few weeks ago I did upgrade from 3.5 to 4.1 The release-by-release (3.5 -> 3.6 -> 4.0 -> 4.1)upgrade we found out as very time consuming, since we were running CentOS 6 on all HOST and Engine too. We decided to install new 4.1 and migrate the VM. The only disadvantage of this upgrade is the VM downtime during the migration. You need to export and import them again.

[ovirt-users] Upgrade path from running 3.6 (centos 7) to 4.1
Hi, i'm running an ovirt cluster in 3.6 (centos 7) no hosted engine. Is it possible to upgrade directly from 3.6 to 4.1? Or this is not recommended. Thanks, Lionel ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
