replace ubuntu 12.10 with Linux Mint 14

[dunngm]

I want to replace Ubuntu 12.10 with Linux Mint 14. I have a live Linux Mint 14 disc and I'm familiar with installing from live distros. My issue is all the programs I have in Ubuntu. How can I "upgrade" to Linux Mint 14 without having to reinstall all my software and settings? This site/forum lists a a very good tutorial on making a backup of data and then a backup of programs if you are upgrading from Linux Mint to a higher version of Linux Mint and then restoring after a clean install, but I don't seem to have the same backup options/program in Ubuntu. Perhaps someone can just tell me the name of the backup program in Linux Mint; the rest of the 'how to' is perfectly clear. I expect to still have to reinstall a few programs, I just don't want to reinstall EVERYTHING. Any help will be greatly appreciated.

This works best if you have separate partitions for root and home.

1 download Booster - Post installation script generator - available from software centre
Use booster to make a list of all your additional programs.

2 Backup your home partition

3 Install Mint over Ubuntu but do not format the home partition.

4 Update Mint

5 Run Booster to install your additional progs.

reboot

Your system should now have all your progs and settings.

NB there may be some conflicts due differences in settings from Mint to Ubuntu.
