Folks, I am looking for the easiest way to transfer my OS, without reinstalling everything from one machine to another. Ubuntu is running on a Asus PC with a 500G hard drive and I want it to run on a Intel Nuc with a 60G SSD.

I have an external usb drive for my data. 

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G     0  1.9G   0% /dev
tmpfs           386M   40M  346M  11% /run
/dev/sda2       454G  6.9G  425G   2% /
tmpfs           1.9G   20K  1.9G   1% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
/dev/sdb1       7.3T  3.1T  3.9T  45% /media/data
/dev/sda1       511M  3.4M  508M   1% /boot/efi
tmpfs           386M     0  386M   0% /run/user/1000

I am a newbie at this, so the easiest the better. I have accessed to the hardwares and it is not critical to have my server running all the time...

Thanks for your help.

If you don't want to use a tool like clonezilla, then what you can do is:

  • take a live or rescue disk or USB stick
  • boot from that
  • partition the disk of your new computer (maybe take a hint from the partition setup on your old computer)
  • either attach your old disk to your new computer or vice versa or connect both computers on a network
  • then copy the contents of the filesystems on the old computer to the new one - see here: https://superuser.com/questions/307541/copy-entire-file-system-hierarchy-from-one-drive-to-another
  • once the content is copied make the system bootable
  • make sure /etc/fstab is correct (i.e. either contains the correct blockdevice UUIDs or contains /dev/sdaX style block device identifiers)
