How to transfer Ubuntu on WSL from one laptop to another?

New to Linux and Ubuntu. I am trying to transfer my old Ubuntu WSL files to my new Windows 11 laptop.

I have gone through similar questions, but none seems to help my case.

I am trying to clone the WSL of my old laptop on a USB hard drive so I can transfer it to my new laptop, but the USB is not listed when I enter lsblk or any other command that lists the drives on laptop.

Results of wsl -l -v from the comments:

  NAME                    STATE      VERSION  docker-desktop-data     Running    2* Ubuntu                  Running    2  docker-desktop          Running    2

I need to transfer files from both Ubuntu and the docker-desktop-data.
