Preserve your custom processors

If you have written custom processors, you can preserve them during the upgrade if you store them in a central location.

  1. Create a second library directory, called custom_lib.
  2. Move your custom processors to this new lib directory.
  3. Add a new line to the nifi.properties file to specify this new lib directory: 
    nifi.nar.library.directory=./lib
nifi.nar.library.directory.custom=/opt/configuration_resources/custom_lib
