nono, the upgrade is live and all your VMs can keep humming. But there = are manual steps involved: Simone can probably update about Hosted Engine which would be somewhat = special, but at least for regular VMs you can currently use: 1) create a new cluster with same settings as your existing cluster 2) remove one host from the old cluster (the one to be = upgraded/reinstalled to EL7). While moving the host to maintenance your = VMs will be migrated to other EL6 hosts in that cluster (make sure you = have enough capacity to do that beforehand, of course:) 3) upgrade/reinstall the host with EL7. If youdon't have anything custom = on the host reinstallation might be the best option 4) add it to the new cluster, installing/deploying it via UI, then it = should come up - this is your EL7-based cluster now 5) manually migrate (Migrate To button) some of your VMs from the old = cluster to the new one (there's an advanced section in the dialog, = allowing you cross-cluster migrations 6) repeat until all your hosts and VMs are on EL7-based cluster, then = you can decommission it, and perhaps rename the cluster back to its = original name Thanks, michal
