In the spirit of tarball :)

We are writing migration scripts that are being executed on the migrated database.

By my understanding this is no different from how the migrations are being handled by Django (qiock look into the migrations folder content will clarify it)

A lot, and by "a lot" I mean really A LOT is in human hands. I cannot stress enough the discipline needed to maintain the project.

But I'm not looking back -0 this is extremely rewarding.
