You cannot move the window if you have borderless mode enabled. To move the window you first need to enable the border by pressing Ctrl+D, then pressing Ctrl+G to use your mouse and drag it to the other monitor. However, if your window already covers the entire screen, it is impossible to enable the window border during the game. You may need to lower your resolution in options.
It is not possible to start the game on a non-primary monitor by default. However, you can do something else: in your windows settings, set the secondary monitor as primary. So the left monitor will be non-primary, and the game will run on your right monitor.
MultiMonitor is an option that enables you to span the game across multiple monitors. So it will run using both monitors at once. I guess this is not what oScarDiAnno wanted.
It might also be possible to trick the MultiMonitor mode without changing your monitor from secondary to primary. For that to happen, your secondary monitor needs to be logically positioned on the left side in windows settings. After that, you disable the "AutoSetResolution" option (to prevent automatic spanning) and go into the game options to choose the resolution for your secondary monitor. Then, supposedly, the gameplay should start on your secondary monitor. However, the frontend menus will still be stuck on your primary monitor's top left corner!
