Thank you for your post.
If you would like to replace one of the devices you are connecting from, you can remove the license activation in the Management Console --> Edit profile (upper right corner) --> License (on the left side) --> click on Deactivate device (choose the relevant ID). To add a new device, you simply just sign in into the Computer & Contacts list with the licensed TeamViewer account on the new device. The new licensed ID is displayed in the Management Console afterwards.
Please let us know, if you have any further questions.
