How to upgrade to woody?

[jennyw]

I'm thinking of upgrading my potato (which has a couple packages from unstable) installation to Woody.  I'm a bit scared, since this seems like a major overhaul and since I've never tried this before. So I was hoping someone could give me an idea of what to expect (like how likely it is I'm going to have to reinstall from scratch).   Do I just change sources.list to include:     deb http://http.us.debian.org/debian testing main contrib non-free   deb http://non-us.debian.org/debian-non-US testing/non-US main contrib non-free   Then do:     apt-get update   apt-get dist-upgrade   Thanks!   Jen
