One of the key features of the MySQL Migration Toolkit is that it can be easily extended and customized to support new data sources. This is done through the use of its Generic RunTime (GRT) Environment.

Extending the MySQL Migration Toolkit to support a new RDBMS requires the creation of two new modules: one module that reverse engineers (ie., retrieves schema information) the source database objects and converts them into GRT objects, and one module that migrates the source GRT objects into MySQL GRT objects. The MySQL Migration Toolkit then converts the GRT MySQL objects into SQL statements that create the target MySQL server objects.

Existing modules can be easily expanded and customized to achieve the perfect migration for individual requirements. New migration “methods” that define how the migration is performed can be added easily. The new methods are listed and can be selected from the Wizard interface or used in migration scripts.
