This guide covers migrating all adopted UniFi devices (APs, switches, cameras) from a Dream Machine (UDM) to a Dream Machine Pro (UDM-Pro) with minimal disruption. It assumes you are replacing the UDM entirely and the UDM-Pro will take the same network role.
This guide has been updated with real-world field experience from an actual UDM → UDM-Pro migration, including the cloud account claiming procedure, Mesh AP tweaks required post-restore, and cellular WAN failover configuration using a designated LAN port as WAN3.
The Raspberry Pi Zero, a marvel of miniaturization, offers incredible computing power in a tiny, affordable package. But its small size often means less direct interaction – no built-in screen, no bulky keyboard. This is where the magic of a headless setup truly shines.
Imagine a silent, power-efficient micro-server, tucked away in a corner, diligently running your automation tasks, hosting lightweight applications, or providing secure network services, all without needing a monitor, keyboard, or mouse. This guide will walk you through transforming your Raspberry Pi Zero into exactly that: a robust, optimized, and secure headless server.
We'll cover everything from the initial OS installation using the intuitive Raspberry Pi Imager, through critical system updates, essential package installations, crucial performance optimizations like ZRAM, and fundamental security configurations. By the end of this journey, you'll have a lean, mean, server machine ready to tackle your projects. Let's dive in and unlock the full potential of your compact companion!
