I have had project which used Rasa since mid 2018, but only recently migrated to version 1.x. Previously I had Rasa NLU and core separated, with separate config files etc. How can I use Rasa X with the old version? E.g. is it possible to specify separate config files for NLU and core, e.g. using the --config argument?
For anyone wondering, I ended up just switching to the new Rasa project setup (created by running rasa init).
