Saving Interface Table Data

Upgrades: All upgrades.

Environments: Development environment only.

Use the appropriate tool to export any data in your interface tables that you want to retain. During the upgrade process, your interface tables are dropped and then recreated. After you have upgraded, you can import this data using the appropriate tools.

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