If you have RAID1, you can just pull one of the mirror drives, move it to a new 
box, and let both systems rebuild to new partners.

Clonezilla is probably the fastest way to copy non-raid disks (lvm works if it 
is on a single drive) because it knows enough about most filesystems to only 
copy the used blocks.  It also lets you use a network share (nfs/smb/sshfs) for 
intermediate storage of compressed images so you don't have to connect the 
source and target drives to the same system or access them at the same time. The 
target disk has to be the same size or larger and you will have some extra work 
to do if the target hardware needs different disk drivers.
