Q Is it possible to migrate to RPI4? #102

Closed skulko closed 5 years ago

skulko commented 5 years ago

Hello is there a way to migrate an Image running under rpi3 to rpi4?

I read in RPi4 Compatibility? #91 that your image is not compatible per se but that the cpu is backwards compatible... so it should be possible to replace the firmware/dtbs files and boot it on rpi4, no?

thank you very much for your projects btw. sorry if this has already beens answered.. br

Yes, it is possible as the image now supports both RPi4 and RPi3 (just a little fiddly, as you will need to expand the size of the /boot partition prior to upgrading, using a tool like gparted, since there are now two kernels to accommodate).

Please see my manual upgrade instructions here.

Closing now as I believe this point is covered. Best, sakaki
