AWS Database Migration Service
#225 · Level 4 · Operations and specialized areas · Migration and transferConcept
Section titled “Concept”AWS Database Migration Service (DMS) moves data from one database to another — while the old database keeps running. First, all the existing data is copied (full load). After that, any new changes in the old database are sent continuously to the new database (change data capture, or CDC). Data can be moved between the same type of database, and also between different types of databases. When the types are different, DMS Schema Conversion or the Schema Conversion Tool is needed to convert the database structure.
