I have LibreElec on a generic SD card, running on a Raspberry Pi 3 B+.
I also have an external SSD hooked up to the Pi with a USB-to-SATA-adapter. I use the SSD as storage for various things.
Is it possible, and how, to move the whole existing system from the SD card to the SSD and boot from there?
Can I do this without destroying existing data on the SSD?
