Power9
IBM's 2017-generation Power processor and server family, the direct successor to Power8 and a common first migration step off it.
IBM Power9 remains a viable migration target off Power8, particularly on the used and refurbished market, but it caps out at IBM i 7.5 ... it does not support the current IBM i 7.6 release, which requires Power10 or Power11.
