I upgraded the server by unzipping into a new folder and then copying (recursively) the entire contents of the 1.16 folder into the existing 1.14 folder and overwriting all.
I am not experiencing the issue described in 6242. 6242 describes world gen problems and no hostiles spawning.
It is rather that mobs are spawning where they should not, and where they did not prior to 1.16. I can take some screenshots of places where creepers and slimes are constantly and relentlessly spawning even where light levels are > 7. There are several others who have reported the same behavior.
I haven't downloaded the world so I can test it on a Win10 client only situation and see if it is server-specific if it will help you troubleshoot the situtiaton
