How to Migrate AP From One Controller to Another

Option 1:

1. Backup the configs of the old controller
2. Restore the configs to the new controller

Option 2:

1. SSH into AP with previous controller’s username & password
2. Reset the AP with this command: ‘syswrapper.sh restor-default’
3. Reconnect to AP with default credentials ubnt/ubnt
4. Type: mca-cli shell > set-inform x.x.x.x:8080/inform (x.x.x.x is the ip of the new unifi controller)

   mca-cli shell
   set-inform 

   
5. Logon to new controller and verify that such AP has been adopted

Sample Output:

rambo@Unifi-Controller:/home/rambo# ssh [email protected]
[email protected]'s password: 

BusyBox v1.25.1 () built-in shell (ash)

      Welcome to UniFi UAP-AC-Pro-Gen2!
UBNT-BZ.v4.3.21# mca-cli shell
UniFi# set-inform 192.168.0.100:8080/inform

Adoption request sent to '192.168.0.100:8080/inform'.  Use the controller to complete the adopt process.

Please note that your SSH session will automatically exit once the device has been ‘adopted’ by the controller.
