Is this a reason to immediately replace every Power 9 system?

No. It is a reason to identify the exact model, support status, IBM i release path, workload criticality, and replacement date before spending more on the platform.

Power 9 Lifecycle Decision Engine: Keep, Maintain, Expand, or Replace

Updated August 11, 2026

A practical framework for deciding whether a Power 9 system deserves another maintenance cycle or a Power 10 or Power 11 replacement plan.

The Practical Reading

Power 9 is mature infrastructure. That is not automatically bad. It simply means each decision should be tied to lifecycle, support, capacity, and migration timing rather than nostalgia or panic.

Checklist

Identify

Record machine type, serial, processor feature, memory, storage, adapters, and OS levels.

Validate

Check IBM support, reseller availability, firmware, and IBM i release fit.

Compare

Price maintenance and parts against a Power 10 or Power 11 replacement path.

Schedule

Put a real date on the next action, even when the answer is to keep the system.
