I was wondering, because I have two other laptops with different linux distritbutions installed on it, three if counting a very light version of slackware on a 3rd old piece of hardware from the early 2000's. In theory it would seem possible I think to achieve more of a transition than an installation, but then again because all the software on these distributions "came from" the repository associated with that Debian based distro so I guess if I did find a way to even do something like this...basically strip away the distro specific aspects and install some gentoo tools like package manager emerge. But in the end I more worried about a clean install missing many of the seemless features I have set up between the scripts, configs, and personal files. What would be the best way to go? A fresh install possibly? And then should I make sure to first sync/copy every file on the system so that later I can start to piece it back together on a new linux distribution and install?

If possible make a disk image. If I could get a penny for everytime I relentlessly asked "Did you get everything" and than after confirmation and format they found out they "Did not have everything", I'd be very rich.

If your specifics aren't in a git/dotfiles/config management system. This opportunity might be a good one to start.
Your disk can crash and then you really lost everything.

So my advice would be, backup and start over. If you have time and want to tinker, look into Gentoo Prefix.

Ok this seems like good advice, but in terms of disk image software what would you recommend. In the past I use dd or fsarchiver. Both seem reliable, but I also want to make sure I'm understanding your instructions do not involve restoring that backup image unless things somehow go wrong with the rest of the plan. Which is to set up the git config for dotfiles, and now that I think about it probably also makes sense to sync/copy all my personal files as well, in /home, /opt, and /root, among other places.

In general doing the backup of data for both laptops before starting fresh seems like a good overall plan. Thanks for the advice.
