Upgrade Guide for DB2 UDB for z/OS and OS/390 > Preparing a Production Environment for Upgrade >

Saving Interface Table Data

Upgrades: All upgrades.

Environments: Production environment only.

Use the appropriate tools for your business to unload any data from your interface tables that you want to retain. During the upgrade process, your interface tables will be dropped and then recreated. After you have upgraded, you can then import this data using your standard tools.

NOTE:  During the upgrade, all custom indexes on interface tables are dropped from both logical and physical schema.
