Sure its possible go to your SQL Managment Studio and find your GunzDB right click it and go to Tasks > Back Up
At the new window pick your backup location then click ok.
Transfer your GunzDB.bak or what ever you named it to your new pc and once you have installed SQL Managment Studio on that create a new database call it GunzDB if that is the name of your old one then right click it and go to Tasks > Restore > Database
This will bring up a new window on that window select "From Device" and then click the "..." this will bring up yet another window but now all you need to do is click "Add" and find your GunzDB.bak
