Phalcon数据迁移与模式迁移分离

Using Phalcon framework and its migrations system, for testing purposes, I need to be able to execute the schema migrations separately from the data migrations.

What I want to do is to have a separate data migrations folder, so on my testing environment I would apply only the schema migrations (for testing purposes, tables should be empty and only populated by fixtures), but on my staging and production environments the data migrations would be applied as soon as the schema migrations are done.

I don't find a way to have two separated sets of migrations in Phalcon. How can I do it?
