teacher to school moving groups

I am moving from teacher accounts to school account. I need to move the teacher created groups to the school account. I have clicked the checkbox on the teacher account and pushed link to school. Nothing happens on the school side. So, I entered the name that the teacher had given the group into the school account. It comes up, but there are no students attached. How do I move groups from teacher to school and keep the names, passwords, workbooks, etc.
