Hello experts, I was hoping to get some help figuring out why this windows server 2016 upgrade keeps failing. Is there a good log or place to start getting some details about why the upgrade will not finish? I have tried maybe 5-6 times, and each time this server gets hung at 31%. I have let it go for a full day, and I can see the CPU is barely ticking and there's no disk activity. I have done an in-place upgrade on 4 other VM servers similar to this, on the same hardware, but there's something about this VM that is unique and not letting me finish. When I hard boot the server, it reverts back to 2012r2 and there's some stuff on here that I don't know if I can migrate, so an in-place upgrade looks like my best bet. Thanks!

An in-place upgrade is very risky and never recommended. Better option is to stand up a new one, patch fully and migrate roles over.
