Yes, this sounds correct.

The part that might 'feel' wrong is the fact the many of the
dependencies are interrelated and some are circular.  You will not be
able to make a nice checklist and work through the dependencies in a
set order.  Instead, you will have to tug on lose strings a little bit
at a time(by trial and error) until the knot comes undone.
