Migrating from Stacer
to Nexis

This page covers the mechanics of switching: installing Nexis, carrying over your configuration, and removing Stacer. For the case for switching — what changed, what's different, feature-by-feature — see Nexis vs. Stacer.

Nexis and Stacer can run side by side — installing one does not remove the other. The order below installs Nexis first, has you reconfigure it, and uninstalls Stacer last, so you have both tools available while your settings still exist in Stacer to reference.

1. Install Nexis

Linux

sudo add-apt-repository ppa:s4solutionsllc/nexis
sudo apt update
sudo apt install nexis

yay -S nexis

chmod +x Nexis-*.AppImage
./Nexis-*.AppImage

macOS

brew tap s4solutionsllc/nexis
brew install --cask nexis

Stacer is Linux-only — there is nothing to migrate on macOS beyond installing Nexis itself.

2. Reconfigure your settings

Nexis does not currently import Stacer's configuration automatically. A Settings Importer that reads Stacer's config directly from ~/.config/Stacer/Stacer.conf is planned but has not shipped — this section will be updated with a link to it once it does. Until then, four areas need manual re-setup in Nexis:

• Startup Apps — re-add any applications you had toggled on in Stacer's startup list, on the Startup Apps page.
• System Cleaner selections — Stacer's chosen cleaning categories don't carry over; re-check which categories (package cache, crash reports, logs, app caches) you want scanned.
• Services — re-apply any systemd service enable/disable toggles you made from Stacer's Services page.
• Preferences — theme, language, and any thresholds set in Stacer are not preserved; set them again on the Nexis Settings page.

Keep Stacer installed while you do this — its Startup Apps, System Cleaner, and Services pages are the easiest reference for what to re-create in Nexis.

3. Uninstall Stacer

Once Nexis is set up the way you want it, remove Stacer using whichever method you used to install it:

• Installed via apt or the PPA (ppa:oguzhaninan/stacer):

  sudo apt purge stacer
  sudo add-apt-repository --remove ppa:oguzhaninan/stacer

  The second line is optional — it removes the PPA itself, not just the package.
• Installed via AppImage: delete the Stacer-*.AppImage file and any desktop entry you created for it.
• Installed via another package manager (dnf, pacman, or similar): use that manager's remove command for the stacer package.

apt purge removes the package but not your personal config at ~/.config/Stacer/ — that directory is left in place. Delete it manually once you're confident you've finished reconfiguring Nexis and no longer need it as a reference.
