<div><br>
</div>
<div>maybe a stupid one. Just want to make sure that nothing goes wrong. We </div>
<div>plan to make a rolling <span style="font-size:10pt">upgrade of our </span><span style="font-size:10pt">landscape going to 3.5.1 in december. </span></div>
<div><span style="font-size:10pt">S</span><span style="font-size:10pt">o we always need </span><span style="font-size:10pt">some hypervisor nodes up and running during the </span></div>
<div><span style="font-size:10pt">process. </span></div>
<div><br>
</div>
<div>Looking at older posts I assume that upgrading the engine should be</div>
<div>sufficient, while hypervisor nodes with vdsm 4.14.17 (from 3.4 repos) and</div>
<div>the active VMs <span style="font-size:10pt">keep on running. The start of the engine after the upgrade</span></div>
<div><span style="font-size:10pt">should catch up and </span><span style="font-size:10pt">resync all </span><span style="font-size:10pt">states.</span></div>
<div><br>
</div>
<div>Afterwards I clean hypervisor hosts one by one and clean/reinstall it into </div>
<div>the <span style="font-size:10pt">cluster?</span></div>
<div><br>
</div>
<div>Thanks in advance.</div>
