Migration assistant didn't move all my files

Hello, yesterday I moved all my files from my old MacBook Pro running SL to my new MBP 15,4. I used migration assistant and my time machine backup, that I had updated minutes before. Now I realized that some folders were not copied.

Do you know where I can find a log regarding the moving process, so I can check which files were not moved?

I remember that at the end of the process I received a warning about this but I didn't take it seriously. It was indeed serious, since about 30GB data is missing.
