1. Confirm workloads moved
Dependencies love to surprise you.
2. Final backup
Keep a restore path for the retention you need.
3. Wipe disks appropriately
Especially if hardware is resold or recycled.
4. Remove from DNS, monitoring, and backups
Ghost alerts are how real alerts get ignored.
5. Update diagrams
Powering off is step one. Wipe disks, pull DNS entries, and update diagrams before the box leaves the rack.
Ask Qutzl to run a decommission checklist with you.
