I need to transfer my OneDrive account from my former university to my new university. What tools are available to do this, or what is the process? I tried mover.io, but they charge $1/GB, and I have a few hundred GB of data.
or you can put all data in one folder and then share it to yourself (to another account) and then retake ownership
You can try Multcloud, it is an alternative to mover.io. It allows you to freely transfer files count 50GB/month. Since you have few hundred GB, you can migrate them separately in several months if you are not in a hurry. Or, you can order its monthly service (only $9.9 for 150GB/month) or Quarterly service (only $24.9 for 200GB/month).
