In this article, readers will learn how to perform advanced adoption of an existing, Managed by Other UAP, on a new controller. A single UAP can only be managed by a single Controller, since a binding exists between UAP and Controller.
1. Open the existing Controller and navigate to the Site page for the existing UAP that is already managed. First click on Settings, and then choose site. The area will be the same for all versions of UniFi but each version may look slightly different than the next.
2. At the bottom you will find Device Authentication. On earlier releases this was called Device Password. Note the username and the password (password is viewed by clicking on the input field), you will be using it in the next step.
3. Return to the new Controller where the UAP appears as Managed by Other. Click on the device to open its properties' window. Choose Adopt, and then enter the proper username and password you took note of in step 2. If a static IP is to be used for the UAP, enter it here. The Inform URL should list the network location of the controller in the following format:
Note: Use the local IP address if the UAP is local to the controller, but if it's a layer-3 adoption use the public IP address or DNS.
4. Click Adopt and the UAP will re-adopt to the new Controller and provision with new settings.
