AWS Database Migration Service now supports migrating multiple databases in one task using MongoDB as a source

AWS Database Migration Service (AWS DMS) expands functionality by adding support for migrating multiple databases in one task using MongoDB and Amazon DocumentDB (with MongoDB compatibility) as a source. Using AWS DMS, you can now group multiple databases of a MongoDB cluster and migrate them using one DMS task to any AWS DMS supported targets including Amazon DocumentDB (with MongoDB compatibility) with minimal downtime.
