How the Upgrade Guide Is Organized

Upgrades: All upgrades.

Use the road map and process topics in How to Perform the Upgrade to guide you through the upgrade process. These topics provide a checklist of the steps required to complete an upgrade, in the order you must perform them. Each step includes a link to a topic that explains how to complete the step. The remaining chapters of the Upgrade Guide for DB2 UDB for z/OS are organized according to the major phases of the upgrade.

• Task topics. Task topics explain how to do each step in an upgrade process, and typically include a procedure. Task topics begin with a gerund, for example Updating File System Attachments.
