Raspberry Pi is an awesome little SBC (Single Board Computer), especially the Raspberry Pi 4 that offers a huge improvement over its predecessor. In this blog post I will highlight what you should consider when upgrading your OS to a new hardware (like RPi 3 to RPi 4) or when you consider the same hardware but different (bigger or faster) disk, so SD card migration to a hard drive.

However, this blog post does not offer a complete guide how to proceed with the migration but a set of insights into the process. Most of all, this is a brief history of my experience with Raspberry Pi as a home server.
