hey guys,

i’ve just upgraded from RPi3 to RPi4 and i had to move hass as well. i also switched from a 16gb card to a 32gb one. i did a full backup on pi3, installed hass on the 32gb card, put it in rpi4, updated my static dhcp in router to match the rpi4 and everything is working fine (after snapshot restore) but i cannot update to superevisor 243
