Can I transfer developed training material from Rise into Storyline without turning grey?

Good afternoon fellow Articulate users

I have a query/quandary/dilemma that I am not sure how to approach.

Due to internet security issues, my department no longer uses Rise to develop material for publication into our LMS. 

I have developed two training courses using Rise that I wish to publish.

What can I do? Is there a way of getting around this? Do I need to copy the course piece by piece into Storyline so that it can be securely published? 

Any advice regarding this would be greatly appreciated. Thank you all.
