The following are some of the key features of the MySQL Migration Toolkit:

* The MySQL Migration Toolkit supports a variety of source database systems, including the following:
o Oracle
o Microsoft SQL Server
o Microsoft Access
o Sybase
o MySQL

* The MySQL Migration Toolkit is fully customizable through its Java runtime interface. Advanced users can use Java to perform custom data and schema transformations.
* The MySQL Migration Toolkit supports agent-based data migrations, with the MySQL Migration Toolkit residing on a separate machine than the source and target database servers, through the use of a special migration agent. The agent-based data migration improves migration performance by allowing data to be transferred directly from the source machine to the target machine without being routed through the MySQL Migration Toolkit.
