If you’re currently running a rpm distro, you can make it easier on yourself by using the duke nukem forever command to make a list of your installed programs: dnf list installed.

Once that’s outputting an appropriate format, dump it into a text file with | oldprogs.txt.

On your new computer, that same duke nukem forever command can be used to install from the list with something like dnf install << oldprogs.txt

I bet you can come up with a way to stuff all that into a neat little one liner that’ll provide error handling, output teeing and everything else!

Nobody mentioned it yet, but my current no hassle solution is to:

just physically move the nvme from one computer to the other

Consider using tar to create an archive of your home directory, and then unpacking that on the new machine. This will help to capture all the links as well as regular files, and their permissions.

Take a minute to think what else you have changed on the old machine, and then take another minute to think how tricky it would be to replicate on a new machine. Downloading the apps again is gloriously easy. Replacing configs, or keys and certificates, is not!

I normally archive /etc as well, and then I can copy out the specific files I need.

Did you install databases? You'll want to follow specific instructions for those.

Have you set up web sites? You'll want to archive /var/www as well.

I just made the move to another computer, using the same distro and DE setup as the old one. So far I managed by backing up ~/ and /usr/ so I could drop in system and programming settings.

I don't know how that will work if you're going for a new distro but it's always good to have your old configs for reference!

tl;dr:

dnf list installed > $anydir/meow

On new computer, with fedora installed and the meow file;

dnf install $(cat $anydir/meow)

I’m also thinking a lot about the best way to move everything from one computer to another if one day I buy a new computer.

I thought I had found a way with Clonezilla, but after trying to clone my Surface Go 1 to an old laptop I had, it didn’t work. Could be because I hadn’t removed the surface specific kernel. But now I don’t feel safe anymore.

Some people are suggesting to copy my home folder which I did, but I’m not sure it would fit my needs.

Basically, my files are taken care of with cloud storage (kDrive by the way), but I’d like to keep the way all my programs and extensions are setup.

So I ain’t sure I was a big help😅

I hope one day we’ll just have some program to prepare an archive to unpack for your next system to make the transition seamlessly. Or just putting the computer side by side and sending everything wirelessly.

I feel like we need this with all the personalization we can have on Linux.

Depending upon how much you have customized it, you could just copy the entire OS, adjust various config files for the new partition UUID's.
