Install the new NiFi version
Install the new NiFi into a directory parallel to the existing NiFi installation.
- Download the latest version of Apache NiFi from the Download location documentation.
- Uncompress the NiFi .tar file into a directory parallel to your existing
tar -xvzf file-name
For example, if your existing NiFi installation is installed in /opt/nifi/nifi-18.104.22.168.0.2.0-76/, install your new NiFi version in a path similar to /opt/nifi/nifi-22.214.171.124.0.1.0-71/.
- Create or update a symlink: /opt/nifi/current → /opt/nifi/<nifi build dir>
- If you are upgrading a NiFi cluster, repeat these steps on each node in the cluster.
