Abstract: A system and method for database migration is provided. In an example embodiment, the database migration technique may include a first connection to a relational database, a second connection to an in-memory database, and a migration framework to analyze the data structures of the relational database so as to identify first and second subsets of data structures. The first subset of data structures is migrated to the in-memory database during an uptime period of the relational database, and the second subset of data structures is migrated to the in-memory database during a downtime period of the relational database.

Abstract: Methods, systems, and computer-readable storage media for data migration in an upgrade procedure executed on a software system include actions of initiating the upgrade procedure, determining a first set of tables of a source database that include data to be converted before being first written to a target database, converting data of the first set of tables to provide first converted data, and writing the converted data to one or more tables in the target database.

Abstract: A system and method for database migration is provided. In an example embodiment, the database migration technique may include execution modules having a first connection to a source database and a second connection to a target database, and orchestration modules adapted to identify first and second subsets of statements from a single storage table, wherein the first and second subsets of statements are executed by the execution modules during an uptime period of the source database.
