we're planning an upgrade of an old 4.0 setup to 4.2, going through 4.1.<br>

What we found out is that when upgrading from major to major, cluster<br>
and datacenter compatibility upgrade has to be done at the end of the<br>
upgrade.<br>
This means that we also require to restart our VMs for adapting the<br>
compatibility level.<br>

Do we require to upgrade the compatibility level to 4.1 before<br>
starting the upgrade to 4.2?<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">No. </div><div dir="auto">Y. </div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

We have more than 400 vms and only few of them can be restarted at our<br>
