AWS updated its Database Migration Service (DMS) Schema Conversion tool to support offline conversion of Microsoft SQL Server schemas and code. Users can extract metadata via standard database commands within their own secure environments, then upload files for conversion. This approach avoids the need for direct connectivity to SQL Server instances, mitigating security review delays and firewall modifications common in enterprise settings.
The offline feature is designed for customers with stringent security requirements preventing external tool access to production SQL Server databases. It provides an equivalent conversion outcome to connected workflows and supports all DMS Schema Conversion targets without extra fees. Region availability is indicated in AWS documentation, but third-party validation of this offline method’s reliability or completeness is not documented.
