This document describes how to migrate to z/OS Version 2 Release 3 (V2R3) from the following releases: z/OS V2R2 and z/OS V2R1.

The document is arranged in parts with chapters 1 and 2 as an introduction for everyone who performs z/OS migration actions regardless of the migration path and migration paths for hardware, chapter 3 for those customers migrating from z/OS V2R2, and chapter 4 for those customers migrating from z/OS V2R1. For chapters 3 and 4, only those actions for the specific migration path are documented.

This document does not explain how to exploit new functions in z/OS. For that information, see the many publications that pertain to the z/OS base elements and optional features.
