You can't beat dd for getting everything exactly the same regardless of what you changed - or just splitting the mirrors and letting each sync to new partners but then you have to reinstall grub. I prefer clonezilla for non-raid configurations but most of the machines I care about are configured with raid1.
Well, actually dd isn't so good in this area. dd will do the whole disk no matter how much data is actually stored on it and for a 500GB disk that can take a lot of time. It also doesn't take into consideration any disk geometry differences.
A better way is to use kickstart script to automate a network install and then to use dump/restore to load the user/application data back.
With remote access cards and vnc kickstart installs this can even be done remotely on a headless server even without a technician present to power it on or off.
