Find your current Power 9 model
IBM i 7.5 runs on selected Power 9 models; IBM i 7.6 does not. IBM i 7.1 is a special offering on selected S922 and E980 systems, not a normal starting assumption for every Power 9 model.
Select your exact model below for its planning notes and catalog details. The release column is a planning boundary; processor features and I/O can require higher minimum levels.

E980 9080-M9S: size the partitions before choosing the replacement
Inventory every IBM i partition and any AIX or Linux partitions that share the server. Capture peak demand and each partition’s software entitlement. Check external storage and management-console compatibility separately from the processor comparison so consolidation retains the required isolation and recovery options.
The existing catalog describes this model’s I/O as: Storage and I/O scale with node and drawer topology. Compare that layout with the devices actually attached to your system; it does not mean the same adapters or disks can transfer to the destination.
If this system runs IBM i 7.1, include the special-offering entitlement and processor configuration. The selected-system exception does not remove the destination’s release requirements.
For a replacement comparison, review E1080 9080-HEX and E1180 9080-HEU. Size these candidates against the actual IBM i workload and release requirement. The comparison does not establish a one-for-one capacity match or an eligible model conversion.

Your installed IBM i release on Power 9
Keep the S922 I/O and partition restrictions with the exact configuration. A model name or shared chassis does not establish the same IBM i layout.
| Installed release | Useful next step |
|---|---|
| IBM i 7.1 | Review the supported software steps and the hardware needed for each step. A release named here is a planning branch, not proof it is installed or supported by every configuration. |
| IBM i 7.2 | Review the supported software steps and the hardware needed for each step. A release named here is a planning branch, not proof it is installed or supported by every configuration. |
| IBM i 7.3 | Review the supported software steps and the hardware needed for each step. A release named here is a planning branch, not proof it is installed or supported by every configuration. |
| IBM i 7.4 | Review the supported software steps and the hardware needed for each step. A release named here is a planning branch, not proof it is installed or supported by every configuration. |
| IBM i 7.5 | Review the supported software steps and the hardware needed for each step. A release named here is a planning branch, not proof it is installed or supported by every configuration. |
If your recorded release falls outside the boundaries above, confirm the exact machine and partition inventory before selecting a destination. Find the model and release information.
Power 9 capacity upgrade or replacement
Eligible OS upgrade to 7.5 or replacement for 7.6.
- Compare IBM i CPW and peak workload before choosing a processor configuration.
- Check memory capacity against installed memory and workload demand.
- Review IBM i licensing and processor tiers for the exact destination.
- Compare the catalog model specifications with the storage and adapter inventory.
Adding resources to an existing server and moving to another server are different jobs. A formal IBM model conversion exists only when IBM offers that exact conversion; an ordinary replacement requires a migration plan.
Migration from Power 9: sequence the changes
If the source runs 7.4 or 7.5, selected Power 11 destinations provide a possible common-release option. A source still on 7.2 or 7.3 needs an OS preparation or cross-release recovery plan before the new server can take the workload.
- Record the current model, release and partition layout.
- Confirm the release sequence and hardware that can run each step.
- Choose the data-transfer method around a tested restore and the available outage.
- Rehearse the move before scheduling the final switch.
Several processor generations may be skipped when the verified source and destination allow it. The number on the server family does not establish a supported direct restore or a live-partition move.
Ask Midland about your Power 9 change
Send the exact machine type and model with the installed IBM i release. Include the processor feature and a summary of the applications that must continue running. Midland can then scope the equipment and migration work together.
