Replying to Upgrading Laptop Question.

Hey guys so Im about to order some more RAM and a faster HDD with more memory for my MBP. I know how to use computers well but when it comes to fixing/upgrading I am a total newb. Tried searching around google a bit and could not find a solid answer so I though I would ask here. Am I going to have an issue with keeping all of my programs that only had one license on them , such as FCP 7 or The adobe suite when I change my harddrive? Or is that information stored somewhere else. I would hate to upgrade and then lose the software I paid money for. I know I could just torrent them again but I like having a real license for my editing software

Hopefully that makes sense and if anyone has done this or can explain the process to me, it would be very much appreciated!

Thanks
