The AWS Schema Conversion Tool makes heterogeneous database migrations easy by automatically converting the source database schema and a majority of the custom code, including views, stored procedures, and functions, to a format compatible with the target database. Any code that cannot be automatically converted is clearly marked so that it can be manually converted. You can use this tool to convert your source databases running on either Oracle or Microsoft SQL Server to an Amazon Aurora, MySQL or PostgreSQL target database in either Amazon RDS or EC2. The AWS Schema Conversion Tool is available for Microsoft Windows, Mac, and Linux desktops.
