 ## Moving *Quality-time*
 
 The easiest way to move a *Quality-time* instance is to deploy a new *Quality-time* instance at the new location and then copy the database contents from the old instance to the new instance. All *Quality-time* data is contained in the Mongo database, so that is the only data that needs to be copied.
