I have used clonezilla and DD for both back up and restore. Some where I have an interactive bash scripted I wrote for using DD. In the past when going from a small drive to a new larger drive the most reliable way I found was to use DD to clone and move the data and the use gparted to expand the partitions. Not the most elegant solution but has worked for me in the past. Just a thought might be worth looking at.
