hi user,

I'm planning to update my virutalization and to fix some system incompatibility.

we've been using this kind of setup since 2014 and as of now we're not having some problem.

the system incompatibility that I mention is that, at first my ovirt-engine base os is CentOS 6.7 and my ovirt-engine first version was 3.5 I believe that version 3.5 supports adding hosts with the base O.S of Centos 6.x, then we decided to update the ovirt-engine version from 3.5 to 3.6, then i begun having problem adding hosts with base O.S of CentOS 6.x, then tried to google it, I found out that ovirt-engine 3.6 does not support adding hosts with base O.S of EL6.x, just to add the new host, I decided to change the base O.S of it from CentOS 6.7 to CentOS 7, i've successfully added it to the ovirt-engine but on the different Cluster, and because of this, some features of ovirt-engine 3.6 was unable to use. By the way, my setup here is self-hosted "ovirt-engine".

now my question is 1. will it still work if I restore my current ovirt-engine backup with base of CentOS 6.7 to a new ovirt-engine base O.S CentOS 7 without messing with the Domain data storage. LDAP and VM(s)?

You should follow [1]. If you already tried deploying a 3.6/el7 host in an existing 3.5 hosted-engine cluster, it will not work. If you can revert everything to 3.5, great. Otherwise, please still try following [1], and share setup logs when you stumble upon problems. Good luck, [1] https://www.ovirt.org/documentation/how-to/hosted-engine-host-OS-upgrade/
