iSeries
An older IBM server name that should not be mistaken for a current model or a future Power 12 product name.
Teams may still call a current IBM i environment an iSeries, but Power 12 planning needs the actual installed machine type, model, operating-system release, firmware, HMC or VIOS dependencies, and support state. The familiar name describes platform history; it cannot answer whether a current system should move to Power 11 or wait for verified next-generation evidence.
