# Migration Guide — PC Multimedia

**Owner:** migrasi IP, NIC, atau kebijakan SSH workstation MULTIMEDIA.  
Inventori: [../server.md](../server.md) · Env: [../../.env.example](../../.env.example)

**Prinsip:** ubah `.env` / ssh config / docs — bukan hardcode IP di skrip.

## Inventori saat ini (2026-07-06)

| Item | Nilai saat ini | File yang harus diupdate jika berubah |
|------|----------------|--------------------------------------|
| Hostname | MULTIMEDIA | docs/server.md |
| IP utama (LAN server) | `10.100.1.14` | `.env.example`, docs/server.md, `~/.ssh/config` HostName |
| IP sekunder (LAN MikroTik) | `192.168.0.18` | `.env.example`, docs/server.md, DHCP MikroTik |
| SSH alias | `multimedia` | `~/.ssh/config`, server-audit/host.md |
| SSH user | `admin` | docs/server.md |
| SSH port | `22` | — |
| Gateway utama | `10.100.1.1` | `.env.example` |
| Gateway sekunder | `192.168.0.1` | `.env.example` |

## Langkah migrasi IP (workstation)

1. **Persiapan**
   - [ ] Catat IP/MAC/gateway lama di [../server.md](../server.md)
   - [ ] Pastikan akses fisik/RDP ke PC jika SSH putus

2. **Ubah IP di Windows**
   - [ ] Network adapter → TCP/IPv4 → IP baru
   - [ ] Tes ping gateway & server infra

3. **SSH & firewall**
   - [ ] `Get-Service sshd` — masih Running
   - [ ] Firewall rule port 22 masih aktif
   - [ ] Host key tetap sama (kecuali reinstall OpenSSH)

4. **Update laptop dev**
   - [ ] `~/.ssh/config` — ubah `HostName` pada `Host multimedia`
   - [ ] `known_hosts` — tambah IP baru atau hapus entry lama
   - [ ] Tes: `ssh multimedia hostname`

5. **Update repo**
   - [ ] [../server.md](../server.md)
   - [ ] [../../.env.example](../../.env.example)
   - [ ] [../../server-audit/host.md](../../server-audit/host.md)
   - [ ] [../../Workspace-Context.md](../../Workspace-Context.md) Server Index
   - [ ] Append [../version.md](../version.md) + [../changelog.md](../changelog.md)

6. **MikroTik (jika IP sekunder berubah)**
   - [ ] Update DHCP reservation MAC `10:ff:e0:3a:7d:15`

## Rollback

1. Kembalikan IP di Windows ke nilai lama
2. Restore `~/.ssh/config` laptop
3. Catat di [../issues.md](../issues.md)
