Abstract: Metadata driven business data migration is provided. An extensible business data destination system is provided having metadata that describes its structure. An intermediate database is structurally synchronized to the extensible destination system prior to receiving source data. Once the structural synchronization between the destination system and the intermediate database has been completed, the intermediate database is populated with source data. Customizable migration overhead information is stored and used to allow highly configurable specification of data migration. Once migration information has been specified, and any required manipulations have been completed with respect to the source data in the intermediate database, a migration tool generates business data in the destination system to complete the migration.
