+# Migration: TrueNAS to Ubuntu + Coolify
+
+## Motivation
+
+- TrueNAS is storage-first OS; not ideal for general-purpose app hosting and experimentation
+- Server idles 99% of the time — underutilized capacity
+- Coolify provides one-click app installs and git-push deploys (useful as a Laravel developer)
+- Current setup makes experimenting with new apps slow (e.g., OpenClaw took 3-4 hours)
+
+## Current Setup
+
+- **OS:** TrueNAS Scale (Debian-based) on NVMe SSD (`nvme0n1`)
+- **Storage:** ZFS stripe pool `tank` on two separate disks (~29T total, ~14.8T used)
+- **Services:** Traefik, Gitea, Servarr stack (Gluetun/ProtonVPN, qBittorrent, Sonarr, Radarr, Lidarr, Prowlarr, Bazarr, Recyclarr), CrowdSec, Dozzle, Watchtower
+- **Paths:** Stacks at `/mnt/tank/stacks/`, configs at `/mnt/tank/configs/`, media at `/mnt/tank/media/`
+
+## Target Setup
+
+- **OS:** Ubuntu Server on NVMe SSD
+- **Storage:** Same ZFS stripe pool `tank`, imported as-is
+- **Management:** Coolify for app deployment and management
+- **Services:** Same as before, plus easy deployment of new apps and Laravel projects
+
+## Migration Plan
+
+### Before Wiping TrueNAS
+
+1. **Document network config** — static IP, DNS settings, hostname, router port forwards
+2. **Back up compose files and configs** — copy `/mnt/tank/stacks/` and `/mnt/tank/configs/` to USB stick or laptop (they're on the ZFS pool and will survive, but be safe)
+3. **Export the ZFS pool cleanly:**
+   ```bash
+   zpool export tank
+   ```
+4. **Note disk identifiers** for the pool (already known from `zpool status`)
+
+### Install Ubuntu
+
+5. **Install Ubuntu Server** on the NVMe SSD (wipes TrueNAS)
+6. **Set up networking** — replicate static IP, hostname, DNS
+
+### Restore Storage
+
+7. **Install ZFS support:**
+   ```bash
+   sudo apt install zfsutils-linux
+   ```
+8. **Import the pool** at the same mount point:
+   ```bash
+   sudo zpool import -d /dev/disk/by-id tank
+   ```
+   Pool should appear at `/tank` — if paths need to match old config, set the mountpoint:
+   ```bash
+   sudo zfs set mountpoint=/mnt/tank tank
+   ```
+9. **Verify data integrity:**
+   ```bash
+   zpool status tank
+   zpool scrub tank
+   ```
+
+### Install Coolify
+
+10. **Install Coolify** (one-liner from their docs)
+11. **Decide on reverse proxy strategy:**
+    - Option A: Use Coolify's built-in Traefik — simplest, let Coolify manage SSL and routing
+    - Option B: Keep existing Traefik + CrowdSec config — more control, but manage it outside Coolify
+    - Do NOT run both on port 443 simultaneously
+12. **Re-deploy services** via Coolify using existing Docker Compose files from `/mnt/tank/stacks/`
+
+### Post-Migration
+
+13. **Verify Servarr stack** — confirm VPN routing through Gluetun works
+14. **Verify Gitea** — confirm repos are accessible
+15. **Set up disk monitoring:**
+    ```bash
+    sudo apt install smartmontools
+    ```
+16. **Set up ZFS scrub cron** (Ubuntu may set this up automatically, verify)
+17. **Test deploying a Laravel project** via git push to confirm Coolify workflow
+
+## Gotchas
+
+- **Mount point must match** — Docker Compose files reference `/mnt/tank/...` paths
+- **Coolify has its own Traefik** — conflicts with existing Traefik if both claim port 443
+- **ZFS pool must be exported cleanly** before wiping TrueNAS, otherwise force-import is needed
+- **Servarr stack VPN routing** through Gluetun may need network config adjustments in Coolify's Docker environment
