Re: Move bookworm system from SSD to NVME

By now I think the first solution from druck will be my first try (when
I get the NVME). I have before been looking at creating an image (as
suggested by Chris Townley today) , but ran in to things I did not
understand, or was ment for an earlier version of raspberry pi os. Then
i posted the question here.

So if we look at the df -h listing from my first post:
raspberrypi@raspberrypi:~ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            3.8G     0  3.8G   0% /dev
tmpfs           805M  6.2M  799M   1% /run
/dev/mmcblk0p2   57G  5.0G   49G  10% /
tmpfs           4.0G  368K  4.0G   1% /dev/shm
tmpfs           5.0M   48K  5.0M   1% /run/lock
/dev/mmcblk0p1  510M   75M  436M  15% /boot/firmware
tmpfs           805M  160K  805M   1% /run/user/1000
/dev/sda2       234G   19G  203G   9% /media/raspberrypi/rootfs
/dev/sda1       511M   76M  436M  15% /media/raspberrypi/bootfs

Then the system to copy is on the 2 last lines. Correct?

And following drucks first suggestion I should run these 2 commands:
1: dd if=/dev/sda2 of=/dev/nvme0n1 bs=1M status=progress
and
2: dd if=/dev/sda1 of=/dev/nvme0n1 bs=1M status=progress

No that wont work, it will copy the contents of of the first partition
over the start of the nvme drive and then copy the second partition over
the top of that.

I think what you meant was to copy to /dev/nvme0n1p1 and /dev/nvme0n1p2,
assuming you have already created two partitions of the correct size on
the nvme disk. (I do it like this if creating additional partitions to
enable running different OS versions, but its not needed for a straight
copy).

The single dd command I gave in my last post copies the whole of the SSD
to the nvme including the partition table and both parititions, giving
an identical drive - as long as it is bigger. The only thing to do then
is to use gparted to update the partition table and last partition to
fill the rest of that new disk.
