Am I the only one that thinks "why does it matter, if I can change the word student, to professional and then get useful answers" is a fairly accurate description of an incredibly arbitrary and unhelpful policy stance? This puts you all in the incredibly tenuous position of killing questions because the OPs gave too much info. vSphere is professional software. Always has, always will be. Any policy ignoring that simple fact is absurd.

@HopelessN00b I see nothing that suggests old gear is off topic for the site, and that goes double knowing how much legacy crap is kicking around the average enterprise. You literally invented that phrase out of mid air, it does not reflect the norms or rules of an acceptable question. Your attitude is shockingly horrible. Stop.

What's the point of "unsupported hardware or software platforms"? "Support" is a thing you pay someone to provide and has nothing to do with the quality of a question.

I'd like to substantiate this answer - I've personally used vagrant for quite literally the exact purpose of running CMS system configurations through a battery of tests.
