How do I convert my survey plus responses of one account (free) to my other account (premium)?

I have two accounts on Qualtrics. One where I am able to export my data (through account of my school) and one where I am not able to export data (my own account for free). Unfortunately, I made my survey in the free account of Qualtric and I cannot export the data. Therefore, I was wondering how I can convert the survey plus response data to the other Qualtrics account where I can export data.

Thank you so much if you can help my out!
