Preventive Service Planning
Abstract
Upgrading your DB2® pureScale® environment to Version 11.1 might require upgrading your environment components. These components are DB2 servers, data clients, database applications, and routines. Upgrading these components requires an understanding of the DB2 database product upgrade concepts, the DB2 pureScale feature, and the DB2 database products.
Content
Your first point of reference for learning how to upgrade each component of your DB2 pureScale 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 is Upgrade to DB2 Version 11.1.

Prerequisites
To convert existing Version 11.1 instances, see Convert instances to the DB2 pureScale Feature.
Ensure that you meet the installation requirements for the DB2 pureScale Feature in Version 11.1 as described in Installation requirements for DB2 database products. For details on how to use the db2prereqcheck command to verify the installation requirements, see Checking installation prerequisites with db2prereqcheck.
Review changes in Version 11.1 from existing functionality in 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
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 to write your upgrade plan.
- Planning your DB2 servers upgrade
- Planning your DB2 clients upgrade
- Planning database applications and routines upgrade
For each component, you must include in your upgrade plan:
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 plans.
To fall back to a previous release after upgrading your DB2 servers, add details to your upgrade plan about the tasks required to reverse a DB2 server upgrade. These details should include any steps required in the upgrade task that enables you to reverse an upgrade.
Plan on how to discontinue the use of deprecated functionality.
- Discontinued or deprecated functionality that affects DB2 server upgrades
- Deprecated functionality summary
Consider upgrading your DB2 servers, clients, database applications, and routines in a test environment to learn how to address any issues that might arise during the upgrade process and to evaluate the impact of changes introduced in DB2 Version 10.5. Also in a test environment, you can determine the length of time and the disk space requirements needed to upgrade your database to DB2 Version 10.5, which are essential in developing an upgrade plan and performing a successful DB2 environment upgrade.
