I see now what I am missing :)
If you copy the full tree to the new drives, it probably will not boot, right?
What a about if you still install a system on the new drives, at least
grub will be working, raid partitions are there. if after copying the
old os it will not boot, it may get you to a (initramfs) prompt.
There you can assemble by hand the md partitions, but you want be able
to run grub-mkimage, I think.
What about if you copy everything but the boot dir? That may give you
a good initrd.img file. In that case having the same kernel running on
both installs will be a good idea.
If even so you still get to the (initramfs) prompt because of mdadm,
you can assemble by hand the md partitions, exit, and - with luck -
the system will boot successfully.
Then you would be able to set the /etc/mdadm/mdadm.conf file and run
Let the experts say if that's just a lot of nonsense. :)
