Bootcamp to Parallel

So I have rmbp 13 with 16gb of ram and I am currently running windows on bootcamp to run excel. However, I find myself missing the mac os when I am on windows since most of my files are on mac and even my calendar and email. I was wondering if buying parallel 10 would be worth it at student price and would it be easy to use if I mainly need windows for microsoft office?
How do I do this if ever? Can I just migrate my whole partition of windows to parallel and delete the partition that I currently have on my laptop? How do I do it? Or a clean install of everything would be easier?

Thanks

 

What's BC? sorry not really familiar with all the terms. Can I delete my partition of bootcamp afterwards and get the disk space back?

 

Now that felt quite stupid! hahaha Thank you for replying.

 

Another question. Windows is not activated on my parallels? When I try to use the same activation code, it tells me that the activation code is being used on another device. I did parallel on my bootcamp? does that make sense? How do I activate it then? Or should I just install windows on parallel and delete my bootcamp entirely?
