I work in a school and manage over 50 iPads. I have a new MacBook and my "backup iPad" says it is supervised by another device. I still have the old MacBook. Is there a way to remove that supervision from the iPads and add it to the new one?

I have two MacBooks. I have sole control over one of them. Our Tech Director wants me to control everything iPad in the school. I am trying to set up Apple Configurtator on the new Mac, transfer all the apps already downloaded, and everytime I plug my "backup" iPad into the new MacBook, it says, "This iPad is supervised by another computer and cannot be used with this computer. Help please!!!
