Please, I need some serious help on this. The only thing I've

select the blade an there is an option for Upgrade between
Reinstall and Configure Local Storage. Well, that option is
grayed-out. There is no documentation available for it... I've
dried the google sea and even a node-level command give this

First, I would recommend to put your host into maintenance mode so
all vms are migrated to others hosts.<br>
There are many ways to upgrade ovirt-node vintage, you can boot the
iso, via ovirt-engine or using directly the ovirt-node-upgrade tool<br>
which btw is called via ovirt-engine.<br>
<br>
However, we do not support upgrade from ovirt-node vintage to
ovirt-node-<b>ng</b> (next). <br>
You can download the ovirt node vintage 3.6 and use the below
methods or ovirt-node-upgrade tool as you shared.<br>
<br>
To download oVirt Node 3.6: <br>
ISO or RPM:
<a class="moz-txt-link-freetext" href="http://jenkins.ovirt.org/job/ovirt-node_ovirt-3.6_create-iso-el7_merged/">http://jenkins.ovirt.org/job/ovirt-node_ovirt-3.6_create-iso-el7_merged/</a><br>
<br>
From: <a class="moz-txt-link-freetext" href="https://www.ovirt.org/develop/projects/node/node/">https://www.ovirt.org/develop/projects/node/node/</a>:<br>
<h2 id="upgrading">Upgrading</h2>
<p>There are 2 general methods for upgrading an ovirt-node
installation.</p>
<p><strong>1</strong>. Through oVirt Engine</p>
<p>Require the installation of ovirt-node-iso rpm on oVirt Engine. A
node is then placed in maintenance mode, and you trigger the
upgrade from the engine interface.</p>
<p><strong>2</strong>. Through oVirt Node installation media (ISO,
CD, USB, PXE)</p>
<p>This approach is done using installation media. Simply boot your
host running an old version of node from new media.
Either PXE, CDROM, USB, SD card, ISO, etc. are supported. Once you
boot from the media, it will bring you to a TUI screen where you
choose upgrade.
That will upgrade and leave existing configuration in place.</p>
<br>
I hope that helps.<br>
