I have a database on SQL Server 2008 on a Windows server and I want to move all of the data to a MySQL database on a Ubuntu server. I have tried using the SQL Server Import and Export Wizard with the MySQL ODBC driver, and it correctly accesses both databases, but the xml files containing the specifications for type conversion did not exist and the specifications were too limited for me to correctly create them. Does anyone know either how to create the type conversion files or where to get a better tool for transferring this data?
I have two suggestions:
1) I hate bringing up commercial products but there is a $49.00 tools to Migrate MSSQL to MySQL
2) Try MySQL's MSSQL Migration forums for further suggestions

There is an old product that went EOL back in January 2010 called the MySQL Migration Toolkit. If you can get a hold of it, you can use it.

I found the archives !!! Here is the MySQL Migration Toolkit

Get the WhitePaper (PDF) from Oracle on the Guide to Migrating Microsoft SQL Server to MySQL (Still Commercial)

According to this MySQL WebPage, the section
MySQL Workbench: Database Migration Wizard claims that the MySQL Workbench has the capability of Migrating DB Objects from SQL Server to MySQL.
Based on Marian's suggestion, I found this answer about replicating in the other direction by setting up the MySQL server as a linked server in MS SQL Server. With MySQL set up as a linked server, I can run SQL queries on both databases at the same time, which provides exactly the functionality I needed to solve this problem.
Have you looked into using SSIS for this task? This is the ETL tool for SQL Server and it has lots of transformations and logic that could help you perform this task.
MySQL Workbench can do this:
It can be installed directly on the MS SQL Server machine (speed advantage!), which needs to be able to access your Ubuntu MySQL Server.
I recently released etlalchemy to accomplish this task. It is an open-sourced solution which allows migration between any 2 SQL databases with 4 lines of Python. Supported RDBMS's include MySQL, PostgreSQL, Oracle, SQLite and SQL Server.
This will take care of the daunting task of mapping one SQL vendor's column types, to another's. Not only will it transfer and translate schema, it will also migrate all data, indexes and constraints across databases.
$ pip install etlalchemy
On El Capitan:
pip install --ignore-installed etlalchemy
from etlalchemy import ETLAlchemySource, ETLAlchemyTarget mssql_db_source = ETLAlchemySource("mssql+pyodbc://username:password@DSN") mysql_db_target = ETLAlchemyTarget("mysql://username:password@hostname/db_name", drop_database=True) mysql_db_target.addSource(mssql_db_source)
MySQL Workbench Migration tool can help you do this task
1) To start the migration process, on the MySQL Workbench main screen, go to Database-> Migration Wizard.
2) We should check the prerequisites to confirm if we can continue the task. If everything looks fine, we can press on Start Migration.
3) In this step, we need to provide the information about the source database, in this case, SQL Server.
We’ll configure our source parameter:
Database System: Microsoft SQL Server
Connection Method: ODBC (Native)
Driver: SQL Server
4) Now, we can check the connection by using the Test Connection button.
5) Then, we need to add the target parameters:
Connection Method: Standard (TCP/IP)
6) And press on Test Connection to confirm the added information.
7) In the next step, MySQL Workbench will connect to our SQL Server to fetch a list of the catalogs and schemas.
8) Now, we’ll choose the Your_database_name database from the list.
We can choose how the reverse engineered schemas and object should be mapped. We’ll use Catalog.Schema.Table -> Catalog.Table option, so in our MySQL, we’ll have selected database and the current tables that we have in our SQL Server database.
9) If everything went fine, we’ll have a list of objects to be migrated.
10) In this case, we have Table Objects, View Objects and Routine Objects. We’ll only select the Table Objects because for the rest of the object we should check the corresponding MySQL equivalent code manually.
11) In this step, the objects from the source are converted into MySQL compatible objects.
12) If everything went fine, we can continue by selecting how we want to create the migrated schema in the target. We’ll use the default “Create schema in target RDBMS” option.
13) Now, let’s check the creation schema process.
14) In the next step, we can check the result of each script execution, and we can check the new database created on our MySQL Server.
15) At this point, we’ll have the database structure, but we don’t have the data yet. Now, we’ll select how we want to copy the data in the MySQL Server. We’ll use the “Online copy of table data to target RDBMS” option.
16) In the last step, we can check the migration report and finish the task.
Another easy method of converting a MS SQL DB to MySQL is using Stellar's DIY tool named Stellar Converter for Database that can directly pick database file of a specific database and provide preview of the convertible tables and after conversion will directly store the data into the specified database installed on your system. In this case you'll have to provide MS SQL database file and after conversion it will be stored in MySQL database installed in the system. You can get free version of this software from Stellar's Official Website.
