How to play safe?
Make sure you always make a backup before any updates, especially if you plan to upgrade your existing installation. 


All system customizations are removed on firmware upgrade. 


Special Note for those on 0.8.8:


The following only applies to the UCK firmware version 0.12.1 and the UCKG2/UCKP firmware version 0.8.8 running UniFi Network 5.9.32.


This firmware includes UniFi Network 5.9.29. If you are coming from firmware 0.8.8/0.12.1 you will need to have a backup to restore your configuration (detailed below).


As always, we recommend making a backup before upgrading firmware.


After you upgrade to firmware 0.8.10/0.12.2 do the following to restore your 5.9.29 configuration: 

If auto backup was configured:

  1. Go to https://<uck_ip>/manage/controllers
  2. Click “Stop SDN”
  3. Click “Restore”
  4. Choose the most recent 5.9.29 backup and click “Restore”
  5. After the restore process is finished, click “Start Up SDN”
  6. Click “Open SDN”. Your controller should now be on 5.9.29.


If auto backup was not configured but you have a 5.9.29 backup:

  1. https://<uck_ip>/manage/controllers
  2. Click “Stop SDN”
  3. ssh <user>@<uck_ip> ‘rm -rf /srv/unifi’
  4. Back at https://<uck_ip>/manage/controllers, click “Start SDN”
  5. Go to https://<uck_ip>:8443
  6. Click “restore from a previous backup”
  7. Select the 5.9.29.unf file and click confirm
  8. Wait a few moments then visit https://<uck_ip>:8443. Your controller should now be on 5.9.29
