are "back up the engine, upgrade/reinstall the OS, then restore", but I<br>
can't see how to actually install CentOS 7 on the engine.<br>

Am I supposed to re-run "hosted-engine --deploy"? Wouldn't that try to<br>
re-register the physical hosts, or can I interrupt it to restore the<br>
backup?<br>
<br>
Or, is there a way to just attach an install ISO to the engine VM and<br>
boot from that?<br></blockquote><div><br></div><div>On 3.6 we release the engine also for el6 so for 3.5/el6 to 3.6/el6 you have just to:</div><div>- set global maintenance mode,</div><div>- add the 3.6 repo to the engine VM,</div><div>- run yum update ovirt-*-setup* on the engine VM</div><div>- run engine-setup</div><div>- upgrade the host to 3.6 setting maintenance mode one host at a time</div><div>- raise the cluster compatibility level</div><div><br></div><div>Then ee have a specific helper utility for 3.6/el6 -> 4.0/el7:<br></div><div><a href="https://www.ovirt.org/develop/release-management/features/hosted-engine-migration-to-4-0/">https://www.ovirt.org/develop/release-management/features/hosted-engine-migration-to-4-0/</a><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
