Universe migration from one database to another

摘要

A semantic layer (universe), which is created on a source database (DB), is migrated to a target DB. The migration includes pre-migration steps, actual migration and post-migration steps. The pre-migration steps prepare the target DB for the actual migration by configuring the target DB and determining the differences between the source DB and the target DB. During the actual migration, data, tables and views are migrated to the target DB conforming to the target database structure, functions and configuration. A new universe is created on the target database and all consumers of the source universe such as created reports are changed to refer to the new universe.
