You are right. You can't go from 3.7 to the latest, which is 4.2. But you don't have to march it through every major version (3.7 > 3.8 > 3.9..) either. Usually there are more than one solution which you can find in the chart http://www.syndrega.ch/blog/#php-and-dbms-compatibility-of-major-moodle-releases.

From 3.7.2 I prefer > 3.7.last > 3.9 (LTS) > 4.1 (LTS).

You might explore carefully whether you need 4.2. It needs higher system software and live shorter than 4.1 which is LTS. Ref https://moodledev.io/general/releases.

For each step there is an Upgrading document page.

To explain "healthy configurations" I use the handbrake analogy. The best engine is of no use if you drive with the handbrake pulled!

It doesn't have to be that extreme, sub-standard software and inexperienced system administrators can waste the energy of the best hardware.

Why are you so afraid of a crisis? Can't you run some kind of rehearsals? You don't always need the full load to come to a go-no-go type of an answer. You can monitor the machine as load ramps up and extrapolate to the expected load. Kind of stress-strain testing. Read the many discussions in the Hardware and performance forum.

If I knew you're using Windows, I wouldn't have joined the discussion. I use exclusively Linux.
