Moving Subsonic to a new Windows Computer

Hi,
I am setting up a new Windows -Computer and would like to move my subsonic-standalone-installation.
On the new computer I want to do a clean Windows-installation and therefore cannot just make an image of the drive.
Also I want to avoid a new subsonic-installation because I'd like to keep the already existing last.fm artist-images.
The new artist-image source is far less fertile, and I learned that my already existing artist-images from last.fm still work together with the new source for new artists, if I keep my installation.
How to do this the best way?
