I'm new to ubuntu. If I wanted to install ubuntu on another computer, how can I move all stuff on my old installation to the new one?

Should I just use tar in terminal to pack my old /*, and then unpack it in the new /*? Does it work? Or should I just move the /home to the new one?

Because on my old installation, I have already installed many developer tools, and I don't want to reinstall the whole system.

Thanks a lot!

My approach: Use deja-dup to back up and transfer my data, and aptik to back up and transfer my installed software. I've used this several times. Not flawless, but close.

You could tar up your /home/ directory to get all your config, but on I wouldn't tar up your / directory and try to restore it to another. To get your new host in the same setup as the current, you could always look in the /var/log/apt/history.log file on the old host to see all the packages you have installed and re-install them on the new one.

Another option would be to use CloneZilla to make a copy of your hard drive onto another. It is a live CD that lets you copy a hard drive.

  • My /var/log/apt/history.log only goes back two weeks.

  • Here's a better way to list all packages that you installed.
