<p>If you have (proper!) references to filesystems/partitions by
UUID in grub and fstab, dd should work for you.<br>
I would expect modern grub to do this already.<br>
All you need to do is make sure fstab is using UUIDs.</p>
<p>I have dd'd running systems to new disks.<br>
So long as you are not updating packages/config during the
transfer, the new image should run just fine.</p>
<p>If the new drive image has substantial low level configuration
changes (eg. BIOS vs EFI boot), you can <br>
wipe out / on the new image and rsync in the existing root
filesystem.<br>
If you take special care to fix up the copied OS to match the new
configuration (eg. grub-efi-amd64 package), things will work there
as well.</p>
<p>Friends, please do not use hardware RAID cards!<br>

have a system with two drives, and I want to move linux
(ubuntu here) <br>
from one drive to another.<br>
<br>
<br>
Context:<br>
<br>
- Original drive is a fixture created by RAID card. Card
messes up <br>
configurations every several weeks, so a want to use a
different drive <br>
on a different physical connection (yes, sata slot from DVD in
this old <br>
IBM System X server :) ).<br>
<br>
- I suspect that dd copy won't work, cause new drive (ssd)
doesn't go <br>
in place of the original one. It goes into a new location, and
<br>
grub+fstab settings would be different.<br>
<br>
- dd takes time, and I want to keep machine operational
during the move.<br>
<br>
- I already installed ubuntu on new drive, hoping to
reconstruct <br>
original file tree in a new place by copying on filesystem
level (vs <br>
low-level dd).<br>
<br>
<br>
Question:<br>
<br>
- How can you do this copying of original system onto new
system?<br>
<br>
- Should it by rsync or tar pack& unpack? What flags to
use? Is tar <br>
complain about skipping socket is safe in system backup for
future recovery.<br>
<br>
- Can there be a catch in this approach?<br>
<br>
<br>
Thank you.<br>
