# Vaultwarden → edge2 LXC — Migration Pilot (+ reusable LXC-migration runbook) — v2
## Changes from v1 (what was corrected and why)

## Context
We're consolidating both Contabo VPSes onto Proxmox. edge2 is up and proven (PVE 8 + PDM). The next phase is evacuating services off the **main Contabo** so it can be rebuilt as `edge1` — moving each service into an LXC on edge2, with the live Contabo as rollback, mail handled last on its original IP.

**Vaultwarden is the pilot** because it's the lowest-risk service: a single container, ~5.3 MB of SQLite data, no external DB, and `SSO_ONLY=false` so local master-password login works even if Authentik is down. This run **doubles as the reusable per-service LXC-migration template** — phases are tagged `[G]` generic vs `[S]` service-specific.

The cutover uses a **proven, low-risk pattern**: public DNS never changes; we stand up the service on edge2, then re-point *one token* of Contabo's Caddy backend to the new instance over the tailnet (exactly how `proxmox.echo6.co` already routes to `100.64.0.6:8006`). Rollback = revert that one token + restart source (~12 s).

**edge2 access (pinned):** `ssh admin@184.174.35.153` (alias `edge2`, key `~/.ssh/contabo2_ed25519`), then `sudo` for every `pct`/`pvesm`/`pveam` command. `root@100.64.0.26` is refused — do not use it.

### Phase 0a — Validate a LOCAL user exists + record to credentials `[S]` ← user-requested GATE
- Take a read-only hot snapshot of the live DB and query `users`: confirm **≥1 account has a non-empty `password_hash`** (= master password set → local email+password login works, independent of SSO). Recon already confirms: **one account `matt@echo6.co`, password_hash non-empty, email verified, enabled → GATE PASS.** Record email(s), `login_count`, verified status.

- **Record to `/home/zvx/projects/.ref/credentials`** under a `# Vaultwarden (vault.echo6.co)` section: the account email(s), `SSO_ONLY=false` (local login enabled), and a note that the **master password is Matt's own secret — not stored anywhere in plaintext** (Vaultwarden keeps only the PBKDF2/Argon2 hash). The `ADMIN_TOKEN` (from `.env`) goes here as admin-panel break-glass.
- **GATE:** if NO account has a master password set, **STOP and surface it** — the local-login safety net wouldn't exist. Also confirm with Matt he knows the master password for at least one listed account (we can't recover it, only verify the account exists).

## Gotchas
- **G1** Stale `caddy.md`/archive mentions a `:3012`/`notifications/hub` WS route — live Caddy has **none** (in-process WS on `:8086`). Confirmed in Phase 0.
- **G2** edge2 `vmbr0` has **no DHCP** and no `local-lvm` → static IP `10.10.10.20/24` + `local` (dir) storage. (Overrides ct-runbook defaults.)
- **G2** edge2 `vmbr0` has **no DHCP** and no `local-lvm` → static IP `10.10.10.20/24` + `local` (dir) storage. (Overrides [[ct-runbook]] defaults.)
- **G3** Source binds loopback-only (`127.0.0.1:8086:80`); LXC must bind the tailnet IP (`VW_TS_IP:8086:80`) so Caddy reaches it. Keep the container-side `:80`.
- **G4** SQLite is in WAL mode with a **live 2.4 MB WAL** → use hot `.backup` (single self-contained file, no `-wal`/`-shm`); never copy a live `db.sqlite3`+WAL naively. Here we also **stop the source first** for zero-loss.
- **G5** Preserve `header_up X-Real-IP {remote_host}` in the new Caddy backend line (edit only the upstream token).
