Data Storage Modules 0.40.0Last updated in version 0.36.0

DMS Module

This module creates an Amazon Database Migration Service (DMS) that makes it possible to migrate data from one source database to another target database. You can use this module to migrate your data into the AWS Cloud or between combinations of cloud and on-premise setups. Currently, this module only support MySQL, MariaDB, and Aurora MySQL engines as source and target databases. Additional support for more database engines will be added in the future.
