This module provides a recursive directory scanner for migrations files.

It helps to organize migration files into sub-directories and keep your migrations directory nice and clean, which might be useful for large custom migrations. See the example below:

migrations
  - foo
    - foo_bar.yml
    - foo_foo.yml
  - bar
    - baz
      - bar_baz.yml

There are no UI and configuration options. All you need is to enable the module.
