If you wish to move an AP to an entirely different master account, you will need to delete the AP from the current network it is associated with, and then add it to a network within the new master account. In CloudTrax go to: Manage > Access Points > List View > select drop-down Action tool in far right field > Delete
If you wish to transfer the AP to a different network under the control of the same master account, you can choose to move the AP to the selected network. In the CloudTrax master account, go to: Manage > Access Points > List View > select drop-down Action tool in far right field > Select Move to Network > select desired network.
If you're using a User Management, the user moving the access point must have "Network Editor" permissions on both the originating network and destination network.
