I'll ask around in the company for more information.
I've worked briefly on wrapping an existing erlang app in a Elixir (Nerves) container and I did have a few issues around dependency management which required small changes here and there, but nothing major.
One area where I usually spend more time than I'd like is to get type specifications in good shape so that dialyzer doesn't report too many warnings, but that gets better with every Erlang/Elixir release.
