Answer

Hi there,

I think your question is whether or not AWS DMS support migration of MS-SQL database tables which does not have primary keys. From their [documentation]( https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.SQLServer.html), **yes** you can migrate from MS-SQL Server containing tables that have no primary keys. Since DynamoDB uses a composite primary key you will have to identify two attributes that will form this primary key from your source tables when preparing your data for migration. Please refer to the following [walk-through](https://aws.amazon.com/getting-started/hands-on/break-free-from-legacy-databases/migrate-sql-server-to-amazon-dynamodb/) on how to migrate data from SQL Server to DynamoDB.

I hope this helps
