If a failure occurs for any reason (such as a save runtime state failure or a module upgrade failure) after the
upgrade is in progress, the device reboots disruptively because the changes cannot be rolled back. In such
cases, the upgrade has failed.
If you need further assistance to determine why an upgrade is unsuccessful, you should collect the details
from the show tech-support [issu] command output and the console output from the installation, if available,
before you contact your technical support representative.
