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

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

Langkah migrasi IP (workstation)

1. Persiapan

   • Catat IP/MAC/gateway lama di ../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
   • ../../.env.example
   • ../../server-audit/host.md
   • ../../Workspace-Context.md Server Index
   • Append ../version.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
