Exporting Interface Table Data

Upgrades: All upgrades.

Environments: All environments.

This topic is part of an upgrade process. See How to Perform the Upgrade.

During the upgrade process, your interface tables are dropped and then re-created. To retain data in your interface tables, use the appropriate tools for your RDBMS to export data before the upgrade and then import the data after you have completed the upgrade.

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