# Migration Checklist — New GTHost Detroit Server
|
|
|
|
**New hardware:** Supermicro 2029TP-HTR, Intel Gold 6152 22c/44t, 192GB DDR4, 2x1.92TB SSD
|
|
**Target OS:** Proxmox 9 ✅ installed by GTHost
|
|
**Old server:** Denver, Silver 4116, $103/mo → cancel after migration confirmed
|
|
|
|
---
|
|
|
|
## Current Status (stopped Mar 28 evening)
|
|
|
|
- ✅ New server provisioned and up — Proxmox 9 installed
|
|
- ✅ PBS datastore disk resized to 1.1TB
|
|
- 🔧 PBS datastore needs to be wiped and recreated — old backups only go to Nov 2025, no point keeping them
|
|
- ⏳ Fresh backup of all current VMs/containers needed before migration starts
|
|
|
|
**Next session — start here:**
|
|
1. Delete old PBS datastore
|
|
2. Recreate PBS datastore fresh
|
|
3. Run fresh backup of all VMs/containers — priority order below
|
|
4. Verify all backups complete successfully
|
|
5. Then proceed to Phase 1
|

## Pre-Migration
|
|
|
|
- [ ] Export OPNsense config (both routers) — System → Configuration → Backups → Download
|
|
- [ ] Delete old PBS datastore and recreate fresh
|
|
- [ ] Run fresh backup — priority order:
|
|
- [ ] OPNsense core router
|
|
- [ ] OPNsense zpack router
|
|
- [ ] zlh-dns
|
|
- [ ] zpack-api
|
|
- [ ] zpack-portal
|
|
- [ ] zlh-artifacts
|
|
- [ ] zlh-velocity
|
|
- [ ] All remaining VMs/containers
|
|
- [ ] Verify all backups show green
|
|

|
|
## Phase 1 — New Server Setup (est. 2-4 hrs)
|
|
|
|
- [ ] Configure network bridges to match current layout
|
|
- [ ] Set up VLANs
|
|
- [ ] Add PBS as backup target on new server
|
|
- [ ] Verify new server can see PBS backup repository
|
|

|
|
|
## Phase 2 — Restore VMs (est. 2-4 hrs)
|
|
|
|
Restore in this order — networking first:
|
|
|
|
- [ ] OPNsense core router (VM)
|
|
- [ ] OPNsense zpack router (VM)
|
|
- [ ] zlh-dns (Technitium)
|
|
- [ ] zlh-proxy (Traefik core)
|
|
- [ ] zlh-zpack-proxy (Traefik game/dev edge)
|
|
- [ ] zlh-monitor (Prometheus/Grafana)
|
|
- [ ] zlh-artifacts
|
|
- [ ] zpack-api
|
|
- [ ] zpack-portal
|
|
- [ ] zlh-velocity (Minecraft proxy)
|
|
- [ ] zlh-back (PBS — if moving)
|
|
- [ ] Game/dev containers
|
|
|

|
|
|
|
## Phase 3 — Verification (est. 2-4 hrs)
|
|
|
|
- [ ] Internal networking between VMs working
|
|
- [ ] Portal loads
|
|
- [ ] API responds
|
|
- [ ] Twingate connector online — update connector to new server if needed
|
|
- [ ] Dev container provisions and browser IDE loads
|
|
- [ ] Game server provisions and Minecraft connects via Velocity
|
|
- [ ] PBS backup runs successfully on new host
|
|
- [ ] Monitoring shows all services
|
|

|

|
|
## Phase 4 — DNS Cutover (est. 30 mins)
|
|
|
|
- [ ] Update Cloudflare A record for Velocity public IP
|
|
- [ ] Update Cloudflare SRV records for Minecraft
|
|
- [ ] Update any other DNS records pointing to old server IPs
|
|
- [ ] Monitor for issues — 30 min observation window
|
|
- [ ] Confirm everything stable
|
|

|
|
|
|
## Phase 5 — Cleanup
|
|
|
|
- [ ] Cancel old Denver server (or let expire)
|
|
- [ ] Update PROJECT_CONTEXT.md with new VM map and IPs
|
|
- [ ] Update OPEN_THREADS.md — mark migration complete
|

## Notes
|
|
|
|
- Everything runs on private IPs internally — no hardcoded public IP dependencies
|
|
- DNS cutover is the only external change
|
|
- Worst case: reinstall Proxmox 8 and repeat
|
|
- IPMI available via GTHost panel for out-of-band access if needed
|
|
- Proxmox 9 ships with kernel 6.14, LXC 6.0 — no API changes required
