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.

IBM i 7.5 Is the Power 9 Planning Ceiling

Updated August 11, 2026

Why IBM i 7.5 can keep selected Power 9 systems useful, while IBM i 7.6 changes the hardware conversation.

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.

Your 4 next moves with a Power 9

Every Power 9 owner lands on one of these. You can mix them, too. Keeping or upgrading buys time while you plan a replacement.

Keep it running

Your Power 9 does not stop working when IBM support ends. Third-party maintenance can cover parts and repairs, often for less than IBM charged.

Best when the server is stable and you need one or two more years.

Upgrade the server you have

More memory, bigger drives, or a faster network or Fibre Channel card can buy real time without a new server. Every part has an IBM feature code, so the upgrade starts there.

Best when you are running out of room, not out of support.

Buy a used or refurbished Power 9

A matching used Power 9 makes a cheap spare, test box, or short bridge. Match the machine type first, because an A model and a G model carry different support dates.

Best for a spare, a test system, or a stopgap of two years or less.

Replace it with Power 10 or Power 11

If you need IBM i 7.6, or want five or more years of IBM support, price a replacement. IBM i 7.6 does not run on any Power 9.

Best when the server has to last past 2027 or the software needs a newer release.
