🗑️ Decommissioning Checklist for shredderv1

Date: 2025-05-01

---

🔐 1. Verify Nothing Critical Is Running

• Confirm all services (e.g., AzuraCast, Docker containers, media playback) have been migrated
• Double-check DNS entries (e.g., CNAMEs or A records) have been updated to the new server
• Ensure any active mounts, Rclone remotes, or scheduled tasks are disabled

---

📦 2. Migrate/Preserve Data

• Backup and copy remaining relevant files (station configs, logs, recordings, playlists)
• Verify data was successfully migrated to the new ZFS-based AzuraCast VM
• Remove temporary backup files and export archives

---

🧹 3. Remove from Infrastructure

• Remove from monitoring tools (e.g., Prometheus, Nagios, Grafana)
• Remove from Ansible inventory or configuration management systems
• Remove any scheduled crons or automation hooks targeting this VM

---

🔧 4. Disable and Secure

• Power down services (docker stop, systemctl disable, etc.)
• Disable remote access (e.g., SSH keys, user accounts)
• Lock or archive internal credentials (e.g., API tokens, DB creds, rclone configs)

---

🧽 5. Wipe or Reclaim Resources

• If VM: Delete or archive VM snapshot in Proxmox or hypervisor
• If physical: Securely wipe disks (e.g., shred, blkdiscard, or DBAN)
• Reclaim IP address (e.g., assign to new ZFS-based VM)

---

📜 6. Documentation & Closure

• Log the decommission date in your infrastructure inventory or documentation
• Tag any previous support tickets/issues as “Resolved (Decommissioned)”
• Inform team members that shredderv1 has been retired
