AWS Schema Conversion Tool review
A free self-hosted choice for schema conversion, assessment reports, and AWS migration workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AWS Schema Conversion Tool is a standalone application for heterogeneous database migrations. It connects to source and target databases, generates migration assessment reports, converts database schemas and application SQL, and applies or exports converted SQL. Its scope also includes data warehouses, ETL processes, and selected big-data migrations. Database administrators and migration teams can use it when moving self-managed or on-premises workloads to supported AWS database services or other supported targets.
The tool has one Free plan, covering database schema conversion, database migration assessment reports, and application SQL conversion. Its conversion workflow supports migration rules for data types, names, and object placement, giving teams control over how source structures are adapted. SQL can be exported or applied directly to target databases. Data warehouse extraction and migration agents extend the tool beyond relational schema work, while AWS DMS integration connects assessment and conversion activities with a broader migration process.
AWS Schema Conversion Tool fits teams working across Amazon RDS, Amazon Aurora, Amazon Redshift, Amazon EC2, Amazon S3, and AWS Snowball Edge. It runs as self-hosted software on Windows or Linux, which suits organizations that need a downloadable desktop application and control over the migration environment. It is less suitable for teams seeking continuous replication or dependency mapping as part of the same product. AWS documentation currently recommends DMS Schema Conversion and describes AWS SCT as the legacy downloadable tool, so buyers should consider whether that direction fits their migration plans. Choose it for free schema analysis and conversion with AWS ecosystem connections; consider another tool when ongoing replication or application dependency discovery is central.
