Goal
Make a long-term decision for mixed-generation fleets.

Steps
1) If mitigations stabilize older devices:

• Keep in reduced role
• Maintain restart schedule
  2) If instability continues:
• Retire devices from KDS duty
• Reassign to non-critical roles, OR
• Replace with modern hardware
  3) Document:
• Models retired
• Failure patterns
• Stability differences
  4) Use findings to guide future hardware standards.

Artifacts to Capture

• Device models and ages
• Symptoms by model
• Restart frequency required
• Final disposition (keep / reassign / replace)
