We are trying to migrate QC ALM to Rally. But the problem is, need to move entire existing folder structure and all test cases to Rally. I have seen in Rally help is possible by setting and running config file.

I am not aware of how to run this config file as I am very new to ALM. If you know any simple way, please share.
