Moving Questions from installed to hosted instance

[Ashish Gururani]

We have a Confluence + Questions self installed instance. We are moving to the hosted offering. I understand there is no official way to migrate the "Questions" content. 

My question is that if we have developers, are there alternate ways to move the Questions such as using the API to read from one and insert to another or by directly digging into the database or something else? 

Thanks for any pointers in the right direction to achieve this.
