Migration and seeds scripts

[Slim Hmidi]

Hi,
I took a look at the documentation and I don't find any section or an example about creating migrations or seeds.
Is it something that is not related to the current ORM or it will be done in the next releases?
By the way, is there any suggestion to do a similar thing?
Do you create a script that links all the models to the DB and synchronize them then create some data or you don't use them at all?
