A story about migrating entire Linux disk via SSH

I bought a new computer and transferred the entire disk to the new environment via SSH.

Why i needed

• I bought a new computer, but wanted to do a clean install of Ubuntu in the new environment.
• The old computer had to be returned and I wanted to import the entire system file into the new environment.
• In the worst case, you can reproduce the old environment in the virtual environment
• I wanted to do it via LAN because there is no adapter even if I pull out the SSD

How it was done

Just run the dd command, transfer the data via ssh and mount it.

Copy of data

Execute the dd command from the old environment to transfer to the new environment. In my environment, when I ran from the new environment, the data could not be transferred normally. (When I tried hexdump, the order of the data changed. I doubted that it was related to Endian, but what about?)

dd if={device} | ssh {user}@{host} dd of={file}
