Upgrading an existing Db2® configuration

Before you begin upgrading your Db2® configuration, ensure that you have read and followed the instructions to prepare your CICS® IA environment and the Db2 considerations.

For more information, see Prepare your CICS IA configuration environment and Db2 considerations.

There are two methods to upgrade the Db2® tables:

Copy the previous CICS® IA Db2® tables to a new database

If you choose to use this method, you must first create a new CICS® IA Db2® database and then use Db2® utilities to UNLOAD from the previous database and LOAD into the new database.

Upgrade the previous CICS® IA Db2® database to the new structure

If you choose this method, you update only the tables that have a different structure from the tables in your previous CICS® IA version. This method is a single database migration method.
Note:
CICS® IA 6.1 does not provide jobs to port your existing collector VSAM files. You must load all of your VSAM data in to your existing Db2® tables before you proceed with the Db2® upgrade. CICS® IA 6.1 provides the upgrade job for the Command Flow data from CICS® IA 5.2 only.
