Upgrade Guide for DB2 UDB for z/OS > About Upgrade Topics >

How the Upgrade Topics are Organized

Upgrades: All upgrades.

Use the roadmaps and process topics in How to Perform the Upgrade to guide you through the upgrade process. These topics provide a checklist of all the steps required to complete a particular type of upgrade, in the order in which you must perform them. Each step includes a link to a topic that explains how to complete the step.

The remaining chapters of the guide are organized according to the major phases of the upgrade. Each chapter includes the specific upgrade tasks you must perform for that portion of the upgrade as well as conceptual and process information relating to those tasks.

CAUTION:  Topics in the chapters may not follow the order you perform them during the upgrade and, depending on your upgrade path, all topics may not apply. You must use the roadmap for your upgrade to determine the required and optional steps and their sequence. If you do not, you are likely to experience difficulties in completing your upgrade.
