DD only re-arranges partitions if used in automatic mode, not in manual mode.

ALLWAYS make a backup.  You never know if the power will go out or hit a power 
surge during the partitioning.

What I do when I want to re-partition a drive.  I have two drives in the box 
so this may only work in part for you.  The second drive is only for saving 
partitions/folders/files I don't want to lose, including personal settings.  

Everything I want to save gets copied to the partition on the second drive.  
You could accomplish the same thing with a CD, DVD or some other storage 
device.  I then disconnect the 2nd drive so it can't get damaged (both data & 
power).

Then it's safe to re-partition using Disk Druid in manual mode.  If I make a 
mistake partitioning, I can always go back and do it again knowing that the 
data can be reloaded from the storage device.  

You might want to ensure you have a separate /home/user partition so you can 
leave it unformatted during install/upgrade to retain your personal 
configuration after the new install.

My way, Your mileage may vary!  Have fun
Tom
