Migrating historical data in the Tivoli Data Warehouse for Tivoli Enterprise Portal

When you enable long-term historical collection for a table, the warehouse proxy creates tables in the Tivoli Data Warehouse.

The tables are created when long-term historical collection is first enabled for a table. When you upgrade to a new release of IBM® Z OMEGAMON® AI for Networks, the tables that were created in Tivoli Data Warehouse must be updated to contain columns for all the current attributes or the tables must be dropped from the Tivoli Data Warehouse.

Data in the Tivoli® Data Warehouse is migrated automatically. No action on your part is required.
