Doing a BCP/mysqlimport is one way per table. Using a tool to do a full database dump is another like or using MSSQL DTS, or a host of other tools one can find readily online. If you want a powerful tool for this migration, you should look at DT/Studio at

No, some data types like smalldatetime, money, smallmoney and image need to be converted to appropriate MySQL data types.

Rewrite them. MySQL supports stored procedures as of 5.0.x releases, so you can experiment with this in the newly released 5.0.2. Note that our production release of 5.0.x should be ready in the next few months, early Q2 likely. Our implementation of stored procedures is based on the ANSI/ISO SQL standard and therefore closely resembles DB2's stored procedure language, not MSSQL T-SQL/transact sql.

You can find more about our ODBC connector here:

It is my understanding that you can use the ODBC driver to configure a connection to a remote linux machine if desired though I have not tested this recently.

No issues to my knowledge, in fact our native .Net connector is available here:
