Raspberry PI3A+ - How to migrate SD card to SSD (boot from USB)

[spanzetta (Stefano Panzetta)]

As written in the title I would like to migrate to SSD (I already have it) to improve stability/performance… but possibly in the easiest way

I tried the Method 2: Create Home Assistant Image From SD Card and Burn It on SSD at https://www.makeuseof.com/home-assistant-migrate-from-sd-card-to-ssd/ which appears to be very easy but… it didn’t work (no boot from USB)

Can someone pls help?

I think that this topic is of interest for many people

Thanks in advance

Pls note that since the PI3A+ has only 1 USB port I have an USB Hub where I attach the SSD disk… (I tried anyway as test to remove the USB Hub and attached the SSD directly to the USB port but it didn’t change anything… no boot!)

I have an USB Hub where I attach the SSD disk

It is recommended to use a powered USB hub (the hub has its own power supply) because the SSD and other devices plugged into a non-powered hub can exceed the Pi USB power limits which causes problems.
