Hello,

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

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

Do we require to upgrade the compatibility level to 4.1 before
starting the upgrade to 4.2?

We have more than 400 vms and only few of them can be restarted at our
convenience.
