Question Regarding Django's South and the Migration of Data

I'm just starting with South and one question that I have is not answered in what I have read so far.

Here is the thing: what about the data? Does South makes a dump of all data into a fixt开发者_如何学运维ure, changes the schema and than reloads all of it? In the case of my model's change be the deletion of a column, does South parse the data removing it?

Thanks!

No. Why would it do that? It simply runs ALTER TABLE statements on the database.
