DataArts Architecture Data Migration

Constraints

• Before importing tables/entities in ER modeling, and dimensions, fact tables, and summary tables in dimensional modeling, ensure that a data connection has been created in Management Center and is available.
• Time filters, and data in the Review Center and Configuration Center cannot be imported or exported. You must synchronize them manually before migrating other data.
• The maximum size of a file to be imported is 4 MB. A maximum of 3,000 metrics can be imported. A maximum of 500 tables can be exported at a time.
