Answer 1

Usually when I need to upgrade my NiFi-Registry, I just replace the lib directory with the new version's lib directory & ext/aws(or any other attached extensions). Then, I look here to see if there are additional changes that I need to look for, and apply them as well and then restart the instance.

In your case, you need to do the same and then only take care of the permissions.

Good luck
