Pi4 - 32bit - 64bit - armhf - arm64

[radi]

Hi,

I using a Raspi 4 until yesterday with buster 32bit system .
Now I have updated to last system first, then I have upgraded to last distri. The Raspi running now on bullseye but with armhf

Now I need a way to switch from armhf to arm64

Is it possible to make a inplace upgrade / switch from armhf to arm64?

Greetings

Unfortunately a *simple* update from ARMHF (32bit Userland & 32 or 64bit kernel) to ARM64 (64bit Userland and 64bit kernel) is not feasible.

There are probably very convoluted ways to achieve but grabbing a spare SD Card is recommended.


Raspberry Pi Bullseye Operating System has not yet been Officially Released

I have tried various methods, just to see if it can be done, but none of them were easy and so far I have been unsuccessful.

I had already upgraded all except one of my 64-bit systems with a clean install. I tested the upgrades on a spare Pi 3B+ and Pi 400.

I have done it successfully, just for the fun of it, but it's difficult, time-consuming, and really isn't worth the hassle. So much so that I haven't bothered to write it up, and it was long enough ago that I forget the gotchas.

Much, much better to reinstall. The usual --get-selections | --set-selections dance, with a backup of /etc, is easier, cleaner, less error-prone, and much more likely to result in a working system. But yes: it *can* be done. Just don't bother.
