Hello,
coming back to this proposed steps, do you think it could be applied also
to single host environment with hosted engine?
In that case a few clarifications needed

4. Reinstall engine vm with el7 and 4.0 engine (the tool will use the
engine appliance, you might too but not sure how exactly).
--> so in my still working 3.6 environment I will install a clean VM with
el7 and at least at the beginning while I provision it, it should have
different hostname and ip from previous engine vm, correct?
And then? Can I shutdown previous engine vm and after that, give the same
hostname and ip to the new el7 vm ?
