DB2 Version 9.7 for Linux, UNIX, and Windows

DB2 servers upgrade

Upgrading to DB2® Version 9.7 requires that you upgrade your existing DB2 servers.

Upgrading your DB2 server requires that you install a DB2 Version 9.7 copy and then upgrade all the instances and databases to be able to run them under the DB2 Version 9.7 copy.

You can directly upgrade existing DB2 Version 9.5, DB2 Version 9.1, or DB2 UDB Version 8 instances and databases to DB2 Version 9.7. Learn details, limitations about the upgrade process, and possible issues that you must be aware of in the upgrade essentials section. Refer to the upgrading DB2 server tasks for details on how to upgrade to DB2 Version 9.7. In the upgrading DB2 server topics, the term pre-Version 9.7 DB2 copy refers to a DB2 Version 9.5, DB2 Version 9.1, or DB2 UDB Version 8 copy.

On Windows operating systems, you have an option to automatically upgrade an existing pre-Version 9.7 DB2 copy. If you choose to upgrade your existing DB2 copy during installation, you only need to upgrade your databases after installation.

If your DB2 servers are running on a release prior to DB2 UDB Version 8, migrate them first to DB2 UDB Version 8, and then upgrade to DB2 Version 9.7. It is recommended that you migrate to the latest fix pack of DB2 UDB Version 8.2. Refer to the DB2 UDB Version 8 migration roadmap for details on how to migrate to DB2 UDB Version 8.2.
