Ubiquiti - Downgrade Controller
ALERT: This is NOT supported, so at own risk!
You can't downgrade controllers unless you have a backup from the controller version you want to downgrade to (or older).
Always make a backup (suggest - settings only) to your PC before upgrading or downgrading so you can get back where you were.
NOTE: If you don't have a backup - then you will need to factory reset your devices, adopt and configure like a new setup.
Downgrade the Controller
SSH in and load previous controller.
apt purge unifi -y rm unifi_sysvinit_all.deb* wget https://dl.ui.com/unifi/5.14.23/unifi_sysvinit_all.deb dpkg -i unifi_sysvinit_all.deb rm unifi_sysvinit_all.deb
NOTE: Replace the version in the wget line with the version you want.
Import your settings backup
