I would simply sudo cp -r everything.

you could simply

sudo systemd-nspawn -bqD /mnt/

from the existing install and run the commands required for your
bootloader of choice, assuming this grub auto thingy does generate UUID
based entries and your fstab (if you still should use fstab at all) does
contain those, too, since sdx would change from x=b to x=a, if you
remove the old drive.
