Being on RHEL 7 OS with 4.0.4 they seems now equivalent

Is this ok [y/d/N]:


BTW:
In my opinion it is not clear in RHEV documentation that if you have a Self
Hosted Engine environment you have to put global maintenance before
upgrading engine.
Inside the Upgrade Guide it is only covered the specific case when you
migrate from 3.6 to 4.0 the Self Hosted Engine, while in minor upgrades at
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/upgrade-guide/chapter-2-updates-between-minor-releases
it is not specified.

Inside the Self Hosted Engine guide at
https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged/self-hosted-engine-guide/chapter-5-maintenance-and-upgrading-resources


when describing maintenance modes it is indeed specified
"
The global maintenance mode must be applied for any setup or upgrade
operations that require the engine to be stopped, such as upgrading to a
later version of Red Hat Virtualization.
"
but in my opinion it should be put in clear also inside the Upgrade Guide.
In case let me know how can I open a documentation bug for this if you
agree.
