The OS upgrade isn't the big issue (and MOST enterprises would install fresh anyway.) The big issue is "Do all my old legacy apps still work, and if not, how do I keep them working so Legal doesn't go apeshit because this piece of shit database they bought in 1972 won't work anymore..."
I didn't mean to imply that it would be the only reason. Of course compatibility is a major issue.
However, for some of us that have a large number of machines scattered throughout a large geographical area, some with shit connections that will never see decent speeds... Deployment of a new OS is a very heavy issue.
We just got everything off of XP a couple of months before the End of Life. It was a 2 year ordeal.
Granted... we normally would start with fresh images... but if the upgrade works as smoothly as it did on my test laptop, and everything turns out to be compatible... rolling out an update through WSUS for existing machines, even ones on a shit connection in the middle of the sticks (using BITS), becomes a major plus. Since we replace machines that are 5 years old anyway, all machines would have a fresh image by the end of that rollout. But the major take-away is we could have the upgrade deployment done within months instead of years. (Staggering the rollouts, and re-imaging only problem machines)
