[ovirt-users] upgrade path from Ovirt 3.5x to 3.6x

Hallo, I needed a quick confirmation on this subject. Our environment is Ovirt 3.511 (yes, I’ll upgrade soon, I know) running on a Centos 6.6 hosted engine VM on a cluster of Centos 6.6 physical servers. Since Ovirt 3.6x will be compatible with Centos 7 hypervisor only, how I’m supposed to upgrade hosted engine, VM and HOSTs? i.e. readme tells us the well known procedure (put hosted eng in maintenance, upgrade, etc) but I will eventually end in a scenario where my hosted engine 3.6 will run on centos 7 VM running (on) a lot of centos 6.6 servers... Please tell me I have not to create a totally different datacenter and export -> import all VMs... Thank you! Andrea Ghelardi
