The VM they both run on is the same - so you'd have to know some basics about that regardless. You'll also have to learn how to read Erlang syntax since there are many 3rd party Erlang libraries you can use from Elixir. The syntax is slightly different from Elixir, but the mental models are pretty much the same, so it's really not that difficult to get a working knowledge of reading Erlang.
