Upgrade a DataFlow service

You can upgrade your Cloudera DataFlow (CDF) service together with all DataFlow deployments in that environment with the push of a button.

On the DataFlow Dashboard select Environments from the left navigation pane.
Select the environment you want to upgrade and click Manage DataFlow.
Click Actions > Upgrade DataFlow.

note
If the upgrade wizard determines that the NiFi version of your DataFlow deployments is compatible with the CDF service after the upgrade, you have the option to skip upgrading NiFi in current deployments. In this case you can upgrade NiFi manually later.
Click Upgrade.
The environment status changes to Upgrading and you see a similar message under Event History:
You can monitor the upgrade procedure in Event History. Click Manage DataFlow then select Alerts.

The message DataFlow Successfully Upgraded in Event History and the Status of the service changing from Upgrading to Good Health on the Environments page signal that the upgrade has ended. Depending on the number of running nodes in the cluster, the upgrade can take more than an hour to complete.

If you had restricted policies in place before the upgrade, run the

aws ec2 describe-volumes --profile <aws-profile> --query
                'Volumes[?Tags[?contains(Key,`kubernetes.io/cluster/liftie-`)] &&
                State==`available`].[VolumeId,State,Tags[?contains(Key,`kubernetes.io/cluster/liftie-`)].Key|[0]]'

command to confirm that no unused volumes were left behind.
