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.
