Upgrading DB2 pureScale environments to DB2 Version 10.1 roadmap

To convert existing Version 10.1 instances, see Convert instances to the DB2 pureScale Feature.

Review changes in Version 10.1 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 9.7: Discontinue the use of functionality that is unsupported in DB2 Version 10.1.
• Discontinued or deprecated functionality that affects DB2 server upgrades
• 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.

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 10.1 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.

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 10.1. 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 10.1, which are essential in developing an upgrade plan and performing a successful DB2 environment upgrade.
