The cc export is quite limited and supports the following Moodle question types:
multichoice, truefalse, multianswer, multichoice, match, essay, shortanswer.
Unfortunately this is because the IMS spec is quite limited in terms of the question types it supports - which you can see here:
The Gift export format supports a couple more than the IMS CC standard and I've seen some external systems implement a Moodle xml
import format, but it's unlikely you'll find an external system that will support the massive number of question types supported in Moodle and unfortunately if you're trying to copy stuff over to another system even if they have a similar question type to Moodle you might need to copy/paste the text across manually for each question.
