Until now, I had Mint 5 Elyssa running with which I was quite happy. Now I would like to upgrade to Mint 9 via dist-upgrade (no fresh install if possible). I guess it should work somehow along these lines:

However, Mint uses a different update-manager and I thought it might be best to use aptitude right away instead of apt-get for this since aptitude handles complex dependencies a lot better.
But I could be wrong and I don't want to break my system completely...
How would I have to change my package repositories? (Any instance of "hardy" to "lucid" and any instance of "elyssa" to "isadora", I guess!?)
Does anyone have any experience with this procedure or any further ideas how to get this working as painless and fast as possible?
