I have installed Ubuntu 12.04 on my computer. But now I want to install Fedora. Is there anyway that I can replace my Ubuntu with Fedora without loosing my installed software? My Linux is installed on one partition, I mean there isn't any other partition mounted as /usr/local or something else.
e.g. MATLAB is installed on my Ubuntu, and I do not want to bother installing it again on a new Fedora.
