I do this on my production servers, too. I just wrote a SIMPLE script
which copies the contents of the file systems to other partitions, after
that I just have to edit the copied /etc/fstab and reboot the system.

The first time of course I also had to reconfigure the boot loader (lilo
in my case).

You can find a not yet finished report about my experience doing so. The
report is in german, but it contains the self explaining script!

My script uses cp, a more elegant solution would be to use tar, but
that's just optimisation.

Hope this helps give an answer to your question. I would say the answer
is: may be no tool exists, because it's a to easy task for a dedicated
tool ;)

Happy hacking!
Patrick
