Upgrading to DB2 Connect Version 10.1 roadmap

If you are upgrading from DB2 Connect Version 9.1 or earlier, you need to upgrade to DB2 Connect Version 9.7 first.

Ensure that you meet the operating system and hardware requirements for DB2 Connect Version 10.1 described at Installation requirements for DB2 database products, and the prerequisites for connectivity to supported System z and IBM i data servers described at IBM i and mainframe support for DB2 Connect.

Review the changes in Version 10.1 to existing functionality from previous releases that can impact your DB2 Connect upgrade:

• Upgrade essentials for DB2 Connect servers
• Upgrade essentials for DB2 servers
• Upgrade essentials for data clients
• Upgrade essentials for database applications
• DB2 Version 10.1 enhancements and changes that affect DB2 Connect

If you are upgrading from DB2 Connect Version 9.5, changes to existing functionality between Version 9.7 and Version 9.5 releases can also affect your DB2 Connect environment upgrade. Review the following changes to determine whether you need to manage the effect of these changes:

• Version 9.7: Upgrade essentials for DB2 Connect servers
• Version 9.7: DB2 Connect enhancements summary

If you are upgrading from DB2 Connect Version 9.7, discontinue the use of functionality that is unsupported in DB2 Version 10.1.

• DB2 Version 10.1 enhancements and changes that affect DB2 Connect

If you are upgrading from DB2 Version 9.5, discontinue the use of functionality that is unsupported in Version 9.7.

The Control Center tools and related wizards are discontinued. IBM® Data Studio and IBM InfoSphere® Optim™ tools are the 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 Table of recommended tools versus Control Center tools. For more details about the discontinuation, see Control Center tools have been discontinued.

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. For each component, you must include in your upgrade plan:

• Upgrade prerequisites

• Pre-upgrade tasks

• Upgrade tasks

• Post-upgrade tasks

You should plan on how to discontinue the use of deprecated functionality. For details, see DB2 Version 10.1 enhancements and changes that affect DB2 Connect.

Follow the upgrade plan for your environment. The DB2 Connect upgrade process for each component of your environment is described on the following topics:

• Upgrading DB2 Connect servers
• DB2 servers upgrade
• Clients upgrade
• Database applications and routines upgrade

The upgrade process for each component includes:

• Upgrade prerequisites

• Pre-upgrade tasks

• Upgrade tasks

• Post-upgrade tasks
