Not sure about that. I have never tried that before. See this link . I think Microsoft have offered some help to backup your email contact. You can take a look at the link and see whether it works.

The best option is to backup your email list, inbox and whatever you had in Windows Mail... Once you do, upgrade your vista to seven and check whether it still there and run normally. If it doesn't, just restore all the things you just backed up...
Consider this a self test method. Try first and learn. It won't hurt if you have backed up all necessary files.
