Re: Moving Applications / Dashboards from Sandbox to Dev, Test, QA & Prod environments
If a manual process is acceptable then you can export from the QMC from one environment then import into another environment. Do keep in mind that the Data Connections will not be included so you may need to create the needed Data Connection. This hiccup likely will be rare once you've matured and are using a stable set of types of data.
If you want a more programmatic work-flow then in theory you can craft up a program using the Sense APIs since they include export and import paths if my memory serves. This will shave time off during the work-flow but may require significant development and testing time on your end depending on your organization's background.
