Question about overwiting a current 'oculussing' number with a new one

I am using my Universities Gear VR Headset and Phone for my Unity project. I have that specific phone's 'oculussing' code/number in my Unity folder.

So when I Graduate, and have to give the University their Gear VR Headset and Phone back I will have to buy my own. So for Unity to build the project's on the new Phone/Gear VR I purchase, do I just need to find the new 'oculussing' code online, and just copy and paste that over the old code (University phone) for it to work?

 Is it as easy as that? As I had a stressful time setting it up all from the beginning so hopefully I dont need to do all that again if its just the code that I need?

Thanks!
