AIX was released by IBM in 1986 and stands for Advanced Interactive eXecutive. It was their proprietary offering of UNIX that was based on the UNIX System V. Over the years, they ported it to a variety of platforms including the early RISC-based RS/6000, their System 370 Mainframes, PS-2 Personal Computers (remember them?), and more recently, the platform you will more than likely find it on, the Power Platform, which is also what the IBM i Series (AS/400) runs on. This often creates confusion when considering your approach to migration because there are two distinct operating systems that IBM offers on the same hardware platform, and the considerations for migrating the applications that run on them are very different. Let’s take a deeper look at AIX and the special considerations it requires for migration to the distributed x86 platform.
