Description Jiri Belka 2017-07-25 10:24:09 EDT
Description of problem:

we recommend to power cycle all VMs after changing cluster level soon.

but we do not have such info in Upgrade Guides[1][2].

Michal Skrivanek noted the power cycle in a thread with following
text:

~~~
note that for migration improvements to be effective (4.0 feature) the
cluster level would need to be further updated to 4.0 compatibility
and migration policy would need to be changed from “Legacy” then. This
4.0 cluster update need to happen only AFTER all the former originally
3.5 VMs are power cycled and running properly as 3.6 VMs! Otherwise
the same migration configuration tweaks may need to be applied (I
suppose it’s mainly the bandwidth speed, but pending confirmation)
~~~

Version-Release number of selected component (if applicable):
4.0/4.1
