Preventive Service Planning
Abstract
Upgrading to DB2 Version 11.1 might require upgrading your environment components. These components are DB2 servers, DB2 clients, database applications, and routines. Upgrading these components requires you to understand the DB2 database product upgrade concepts and the DB2 V11.1 database products.
This roadmap will help you navigate through the available information and resources related to upgrading from DB2 Version 9.7, DB2 Version 10.1, or DB2 Version 10.5 to DB2 Version 11.1
Content
Your first point of reference to learn how to upgrade each component of your DB2 environment and how to create an upgrade plan is the Upgrading to DB2 Version 11.1 guide. The content of this guide is available in IBM Knowledge Center. The highest level topic of this guide is Upgrade to DB2 Version 11.1.

Prerequisites
If your DB2 servers are running on a release before DB2 Version 9.7, upgrade them first to DB2 Version 9.7, DB2 Version 10.1, or DB2 Version 10.5, and then upgrade to DB2 Version 11.1.
Ensure that you meet the operating system and hardware requirements for DB2 Version 11.1 as described in the Installation requirements for DB2 database products topic.
Review changes in Version 11.1 to existing functionality from previous releases that can affect your DB2 environment upgrade:- Upgrade essentials for DB2 servers
- Upgrade essentials for data clients
- Upgrade essentials for database applications
- Upgrade essentials for routines
- Changes in existing functionality
- Version 11.1: Discontinued or deprecated functionality that affects DB2 server upgrades
- Version 11.1: Discontinued functionality summary
- Version 10.5: Discontinued or deprecated functionality that impacts DB2 server migration
- Version 10.5: Discontinued functionality summary
The Control Center tools and related wizards was discontinued in Version 10.1. IBM® Data Studio and IBM InfoSphere® Optim™ tools are recommended tools for performing tasks that are similar to the tasks that you previously performed using the Control Center tools. These recommended tools also provide enhanced features for tasks previously performed using the Control Center tools. For a mapping between these recommended tools and Control Center tools, see the Table of recommended tools versus Control Center tools. For more details about the discontinuation, see the Control Center tools have been discontinued topic.
There is no utility to fall back to a previous release after upgrading your DB2 servers. Refer to the Planning section for details.
Planning
Planning your DB2 environment upgrade requires you to determine a strategy on how to approach your DB2 environment upgrade and create an upgrade plan that includes all of the upgrade process details.
Determine all of the upgrade process details for each component in your environment that you need to know about to write your upgrade plan.- Planning your DB2 servers upgrade
- Planning your DB2 clients upgrade
- Planning database applications and routines upgrade
Upgrade prerequisites
Pre-upgrade tasks
Upgrade tasks
Post-upgrade tasks
Review APARs and known issues related to upgrading to DB2 Version 11.1 in the Troubleshooting section. If these issues impact your DB2 environment upgrade, add the actions on how to resolve these issues to your upgrade plan.
To fall back to a previous release after upgrading your DB2 servers, add details about the tasks required to reverse a DB2 server upgrade to your upgrade plan . These details should include any steps required in the upgrade task that enable you to reverse an upgrade.
