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.
