# IP Address Migration Plan

## Status: PAUSED

**Completed 2025-12-22:**
- [x] All LXC gateways fixed to 10.4.2.1 (OPNsense)
- [x] UniFi set to static 10.4.2.16
- [x] Gitea set to static 10.4.2.17
- [x] Immich set to static 10.4.2.30

**Pending:**
- [ ] Media stack IP reorganization (10.4.2.20-29)
- [ ] Pi-hole migration (10.4.2.129 → 10.4.2.11)
- [ ] KavNas / Elantris IP updates
- [ ] Traefik config updates for new IPs

## Migration Order

**Phase 1: Fix gateways only (no IP changes)**
- Restart not required, just config update

**Phase 2: Migrate non-critical services**
1. Media stack (Sonarr, Radarr, etc.) - low impact
2. Docker hosts
3. Game servers

**Phase 3: Migrate core services (brief downtime)**
1. Authelia
2. Vaultwarden
3. UniFi
4. Gitea

**Phase 4: Migrate DNS (coordinate carefully)**
1. Update all DHCP clients to use new Pi-hole IP FIRST
2. Then migrate Pi-hole

**Phase 5: Update Traefik configs**
- Update all backend IPs in Traefik route configs

## Post-Migration

1. Update OPNsense DHCP static mappings
2. Update docs/INFRASTRUCTURE.md
3. Update Traefik configs
4. Test all services
5. Delete this migration plan file

## Commands Reference

**Change LXC IP and gateway:**
```bash
pct set <vmid> --net0 name=eth0,bridge=vmbr0,gw=10.4.2.1,ip=<NEW_IP>/24,type=veth
pct reboot <vmid>
```

**Add DHCP static mapping in OPNsense:**
Via UI: Services → DHCPv4 → [LAN] → Static Mappings
