Verifying CFM 2.1.5

Before continuing the upgrade process by migrating NiFi and NiFi Registry data, you need to verify your CFM 2.1.5 installation.

If you updated the Initial Admin Identity (nifi.initial.admin.identity) after the initial NiFi service installation, select Actions | Reset File-based Authorizer Users and Policies before you start the NiFi service. This archives the existing users.xml and authorizations.xml files and new ones will be generated based on configuration changes. Similarly, if you updated the Initial Admin Identity (nifi.registry.initial.admin.identity) after the initial NiFi Registry service installation, select Actions | Reset File-based Authorizer Users and Policies before you start the NiFi Registry service.

  1. Start the NiFi service.
  2. Start the NiFi Registry service.
  3. Verify NiFi and NiFi Registry started successfully securely over HTTPS.
  4. Log in to NiFi using your authorized admin user.
    You should see a blank canvas.
  5. Log in to NiFi Registry using your authorized admin user.
    You will see no resources.
  6. Once you are satisfied that all services are working correctly, shutdown both NiFi and NiFi Registry services and continue with the migration.
  7. Remove flow.xml.gz and flow.json.gz generated by CFM 2.1.4 NiFi during verification startup. (Default location is /var/lib/nifi/.)

When you are ready to proceed, your next step is to shut down the source services.
