How do I migrate my Ubuntu 18.04.5 Installation to my New machine

I'm new to Ubuntu. i need to know how can I back up my current installation for reinstall on my new machine without losing my Settings and applications.

Answer 1

Using dd to Clone File System from Old Drive to New Drive

• Create Live Ubuntu USB and Boot it.

• Plug in Target drive, (must be at least as large as Source drive).

• Open Gnome-Disks to confirm drive designations, sda, sdb, etc.

• In Terminal run sudo dd if=/dev/sdx of=/dev/sdy

  Where sdx is the Source drive and sdy is the Target drive. Double check that the Target device designation is correct, one typo can overwrite your OS.

  Some people prefer to add a block size, such as bs=256k, but I do not bother.

  The process may take a long time without showing activity.
