Upgrading to a new release of DB2(R) database product might require migration of your environment components. Migrating these components requires an understanding of DB2 database product migration concepts and a thorough understanding of DB2 database products. For example, if you have an existing environment using DB2 UDB Version 8 products and you want to install DB2 Version 9, then you must migrate your environment.

The migration process consists of all the tasks that you need to perform to have your DB2 environment running successfully on a new release. The migration of each of the components in your environment to DB2 Version 9 requires that you perform different tasks:

• Migrating DB2 servers involves migrating your existing instances and databases so that they can run in DB2 Version 9.
• Migrating DB2 clients involves migrating your client instances to keep the configuration of your existing DB2 clients.
• Migrating database applications and routines involves testing them in DB2 Version 9 and modifying them only when you need to support changes in DB2 Version 9.

• Migration to DB2 Version 9
• Configuration of DB2
• Administration of DB2
• Tuning and performance of DB2
• High availability disaster recovery
