Pre-upgrade tasks

Upgrade paths
Before you begin the upgrade process, it is important to understand your upgrade paths.
Review credentials
If you are using the NiFi Certificate Authority (CA), you must perform as series of activities to ensure that your certificate credentials are correctly propagated after upgrade.
Stop Services
You must stop Ambari Metrics, Log Search, and the Amber Server and Agents before you upgrade. If you are upgrading HDF services on an HDP cluster, you must stop NiFi and NiFi Registry before upgrading to Ambari 2.7.0, HDP 3.0.0, and HDF 3.2.0. When you are installing HDF services on an HDP cluster, manual installation is required post-Ambari upgrade.
Verify NiFi Toolkit Version
Ambari 2.7.0 verifies your NiFi Toolkit versions, and requires that you have one that matches the version of NiFi and NiFi Registry that you have installed. Before you begin the upgrade process, verify that you have the necessary version of the NiFi Toolkit.
