Abstract: A client of a database service may request a migration of a remote source database to a target database provided by the database service, where the source database and target database are published by a database vendor. Responsive to the request, a migration tool published by the database vendor may be selected from among multiple migration tools. The migration tool may derive a schema from the source database and create the target database according to the derive schema. The migration tool may then extract data of the source database using native application programming interfaces (APIs) provided by the vendor. The extracted data may then be imported into the target database using one or more additional native APIs. The migration tool may then initiate replication of transactions performed at the source database to the target database.

Abstract: Systems and techniques are disclosed for determining and provisioning and data resources for use in migrations data processing systems. Source data processing system metadata may be used to estimate data storage requirements for a migration and subtask parameters may be used to determine processing requirements. Migration resources may be determined based on these requirements and provisioned to perform migration operations. A migration may be monitored for resource utilization and resources allocated to the migration may be adjusted to increase migration efficiency and performance.
