It is possible to create a backup of the existing databases, the existing files, and configurations in the FireStart installation folder. The script to achieve this is stored under the path: C:\Program Files\FireStart\FireStart Resources, it runs without any parameter and the folder structure defined into it is the default one of FireStart.
Bear in mind that this script is not fully supported by support as the paths, environment settings and permissions may interfere with it.
Run this with administrator rights and set the right database path.
