This document discusses DB2PG, a tool for migrating data between different database management systems. It began as an internal project in 2016 and has expanded its supported migration paths over time. It can now migrate schemas, tables, data types and more between Oracle, SQL Server, DB2, MySQL and other databases. The tool uses Java and supports multi-threaded imports for faster migration. Configuration files allow customizing the data type mappings and queries used during migration. The tool is open source and available on GitHub under the GPL v3 license.
