Preserving your custom processors
If you have written customer processors, you can preserve them during the upgrade if you store them in one centralized location.
Create a second library directory, called custom_lib.
Move your custom processors to this new lib directory.
Add a new line to the
nifi.propertiesfile to specify this new lib directory:nifi.nar.library.directory=./lib nifi.nar.library.directory.custom=/opt/configuration_resources/custom_lib
