Summary: Express Upgrade: UI - Disallow Downgrade when performing
upgrade from HDP 2.1 -> 2.3
Key: AMBARI-13573
URL: https://issues.apache.org/jira/browse/AMBARI-13573
Project: Ambari
Issue Type: Task
Components: ambari-web
Affects Versions: 2.1.3
Reporter: Xi Wang
Assignee: Xi Wang

The UI for stack upgrade always allows performing a Downgrade in the case of an
error, or during several checkpoints.
In the case of an Express Upgrade, we will not allow a Downgrade because of the
complexity involved.
