Tip for a good Database Converter Tool

I need often to convert a database from a database server to another, for example convert a database in MSSQL to a PostgreSQL or convert a MySQL to PostgreSQL, but also convertion between MySQL and Firebird.

Is there a good tool that allow to convert a database from/to different kind of database server ?

• I've found some interesting converter, therefore i answer myself, maybe this tool could be useful to someone else :

  • ESF Database Migration Toolkit (http://www.easyfrom.net/): This toolkit dramatically cuts the effort, cost, and risk of migrating to/from any of the following database/file systems: Oracle, MySQL, SQL Server, PostgreSQL, IBM DB2, IBM Informix, InterSystems Caché, Teradata, Visual Foxpro, SQLite, FireBird, InterBase, Microsoft Access, Microsoft Excel, Paradox, Lotus, dBase, CSV/Text and transfer any ODBC DSN data source to them.

  • Database Converter (http://sourceforge.net/projects/dbcvt/): A generic metadata, data, and progam migration tool for various databases.Create, review, and modify migration defition with/without database connectivity.Execute database migration or generate relevant SQL and data files as per user choice.
