Moving from armv7h to aarch64 without full reinstall

Postby ivanich » Tue Aug 24, 2021 9:24 pm

I was able to change arch from armv7h to aarch64 on my rpi4 without full reinstall. Basically I used migration guide from archwiki for x86 to amd64, anyway there was some issues with package signatures checks(gpg and Sha) but it can be resolved with reinstallation of packages which actually do signature check including pacman keys and so on. Sorry no guide but just want to say its possible to not bother with full reinstall and moving configs.

Thats cool. Could you please post a link to the migration guide you used. I seem not to be able to find it.

I'm looking to do this soon, as I'm upgrading my RPi2 to an RPi4. It hadn't occurred to me that the RPi4 could run arm7h builds. Will it boot if I just put the RPi2 SD card into the RPi4? Did you need to do anything else to prepare the SD card for this prior to swapping over?

$this->bbcode_second_pass_quote('smilerish', 'I')'m looking to do this soon, as I'm upgrading my RPi2 to an RPi4.

I've since realised that the RPi4 build is armv7h anyway, and you were converting it to aarch64. Sorry to have taken this a little off-topic!
