Purpose of this information

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

The document is arranged in parts, with chapters 1 and 2 providing 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 who are migrating from z/OS V2R2, and chapter 4 for those customers who are migrating from z/OS V2R1. For chapters 3 and 4 only those actions for the specific migration path are documented.
