A replacement Power server can give your IBM i applications more capacity and support a newer operating-system release. The useful choice depends on the model and OS you run today: some needs can be met by adding resources, while a release beyond the model’s limit requires different hardware.
Hardware support and IBM i software support have separate lifecycles. Check both for the exact configuration, then compare the application and licensing work with the replacement quote.
