I've just finished updating my work Windows boxes to Server 2019. We are a small firm with three DCs, a FS/PS, ePO (Mcafee/Trellix), RDS/RDG. The ePO at least was 2008 R2 originally. I always do inplace upgrades these days. If you do a search you will probably find that I am apparently so wrong that I need to report into Room 101. I think that what goes wrong is an inability to look at logs - laziness. Windows has rather a lot of logging. It took Linux years to catch up with journald (Events) plus various random text logs in /var/log. No matter how much logging you have, getting technicians to actually look at the bloody things is a really hard problem. The little darlings think they are omnipotent and can deploy a cure based on what I call wankery. It might work but probably doesn't. Medics are way ahead of us here - I've never heard the term contra-indication in IT. Perhaps we should learn from experts in dealing with weird symptoms and very, very complicated diagnosis.
