Every time you migrate the report database, detailed information about the migration done on the report database is stored in the tdq_migration table in the datamart.
To access the migration table in a specific database connection, do the following:
Follow the steps outlined in Migrating the distant database.
In the DQ Repository tree view, expand Metadata > DB Connections.
In the relevant database connection, expand the report database and then in the Tables folder, right-click the tdq_migration table and then select Preview Table from the contextual menu.
The SQL Editor is displayed showing all migration information held in the migration table.
The table below describes the information presented in the migration table:
