Start New NiFi

In your new NiFi installation:

1. Start each of your new NiFi instances.

2. Verify that:

   • All your dataflows have returned to a running state. Some processors may have new properties that need to be configured, in which case they will be stopped and marked Invalid ().

   • All your expected controller services and reporting tasks are running again. Address any controller services or reporting tasks that are marked Invalid ().

3. After confirming your new NiFi instances are stable and working as expected, the old installation can be removed.
