Where can I find good examples or tutorials for sqlalchemy-migrate
In [this thread][1] someone pointed me to use **sqlalchemy-migrate** to help with a fast-changing web application using sqlalchemy. 
However a [Do It Yourself method][2] was also recommended consisting in manually writing CSV columns for the new database schema, and finally import them. 

The problem is that I can't find **real-world examples of sqlalchemy-migrate**. Ressources that I have found [at best][3] decribe adding a single column or a column rename. The official documentation essentially describes the API and it's hard to see how to use migrate effectively. From the doc I cannot even know if migrate could **help changing the database engine**, from sqlite to mysql for example, while the DIY solution would to the job.

I really want to see code that would make some **non-trivial transformations of a database schema** and proving that migrate is really a useful tool. 


Where can I find good examples/tutorials for sqlalchemy-migrate ? 

Thanks !
