I think it would be easier to just make a clean install. If you want to migrate your configurations and preferences, you can just backup your home directory and move it back after installing the OS (I personally have a separate home partition that I can keep between distros).
As for your actual issue, you should look up creating a disk image using dd and then moving that image to another machine and restoring it back using dd.
Refer this article on how to create a disk image and restoring from it: *www.cyberciti.biz/faq/unix-linux-dd-create-make-disk-image-commands/
I'd suggest testing this out before actually doing it.
Edit: In the article, the example used is for the entire hard drive. For indivitual partition you will have to give something like this
Then when restoring, create a partition before restoring the image and then restore into it.

dd if=/dev/sda2
instead of dd if=/dev/sda
, where 2 is the partition number. You can identify the partition number by running fdisk -l
