[ubuntu] Complete System Transfer - reality check

view story

http://ubuntuforums.org – For some unusual reason my disks in my RAID 5 config have started failing. Now they haven't all failed at once, and i they did I would be looking at the RAID controller as the cause. I noticed the other day that two or three disks had an orange light. This prompted me to take some drastic action because I wanted to upgrade the disk sizes anyway. I have ordered 6 new hotswap disks and a new RAID controller as my old controller is not compatible with the larger disks. I have looked at some ghost image software but wanted to know what the community thinks my best options are to transfer (Hardware)
