If the light is off, you can pretty much assume the power to the old switch is off. And, if you aren’t comfortable doing this yourself, get a good electrician to do it!
Next, once the power is off, remove your old switch. Don’t completely remove it, as you will want to take a photo of the existing wiring in case you need to refer to it later (or, gasp, put the old switch back).
