That's assuming the machine was running LVM.  This thing is old enough
that LVM wasn't an option when it was first assembled (although the
kernel is current). :)

Migrating from one disk to another is exactly the reason here.  The new
drive will replace the old.  I don't want an image for a backup, I want
an image to migrate the drive.  But I also didn't really want to shut
down the system just in the off chance the drives didn't want to come
back up to be copied.  I don't have a choice in the matter, it was
wishful thinking.

Above.  Imaging for the purpose of migrating the disk, not a backup
method.  However I don't need versioning, though.  This is my personal
server, nothing changes unless I make the change myself in which case
I've already duplicated whatever I'm changing.
