Live zero downtime migration of databases with disparate schemata

Abstract:

Described embodiments provide systems and methods of migrating clients between databases with different schemas. A database migrator may identify a first database accessible by the client including a first data object maintained in accordance with a first schema. The database migrator may generate, using the first database, a second database including the first data object from the first database. The database migrator may store, onto the second database in accordance with a second schema, a second data object received by the first database subsequent to generation of the second database. The database migrator may convert the first data object of the second database from the first schema to the second schema. The database migrator may migrate the client from the first database to the second database responsive to the completion of storing and converting.
