Excuse the basic question and sorry if it has been answered. If i have an RPi4 with HAOS 11.4 on it with everything working, can I simply pop the SD card into the RPi5 and expect it to work, or do I need to start again?

I too would love this solution over a full rebuild haha
You cannot simply move the microSD card from a RPi 4 to a RPi 5. The operating system is unique for each platform.
However, you can create a Full Backup in Home Assistant, and then simply restore that backup file to the new RPi 5, which will save you a ton of time.

Hi Ogiewon
Have you trye to restore a backup from RPI4 to RPI5, mine is failing all the time.
I tried yours but why its not automatically connecting to the wifi setup already created? anyway to connect to wifi? as I am seeing nothing for ip address etc
When running the RC build on a RPI5 everything works fine. When I cut the power off several times everything boots up after a while on the Raspberry Pi 5. = OK
But when I update it to 11.4 and I cut the power off, the SD card is corrupted and I have to re-install everything, probably something with the 11.4 build?? Any solutions, waiting for the official build but I think it will be the same shizzle.
This is not my HAOS image. It is the Official Home Assistant Team’s Raspberry Pi 5 image. You’d need to ask them about whether or not WiFi is supported at this time.
Looks like it is a known issue that has been reported to the development team.

I have not tried it myself. Does your RPi 5 have enough storage to properly handle the restore of your existing system backup?
I wonder if there is an add-on, or similar, in your current configuration that is not yet working on the RPi 5? Just a hypothesis. As a test, you could perform a partial backup (HA Core + other ‘standard stuff’) on your existing system, and then try to restore that to see if it works.
Same here, trying to fix it for hours, should have taken a look here first

same problem with Raspberry Pi 5
The problem I have the Problem 2 time with two different SD-Cards
same problem with Raspberry Pi 5 8GB, SSD 500GB, not starting - boot
The issue has been around in the 11.3 beta and RC and is still here in the 11.4 build. It will be resolved eventually of course, but for now… rebooting your Pi might kill your HA installation.
Just installed haos_rpi5-64-11.4.img on my Pi 5 and works so far…
I am on 11.4 and configuration of WiFi works well, just I did it in the HA GUI after setup with cable.

Same thing happens to me.
After updating from 11.3.rc1 to 11.3.rc2 and rebooting the OS.
Crash on boot, connecting the PI5 to a screen, I saw on the boot sequence an error like system panic mode etc… and then reboots on infinite cycles…
After updating from 11.3.rc2 to 11.3 and rebooting the OS, Crash on boot.
After updating from 11.3 to 11.4 and rebooting the OS, Crash on boot.
Every time have to re-flash the sdcard from the latest downloaded image.
And then do a full restore of previous backup.
(and doing a full backup every time … before rebooting, and save it on my laptop)
Eventually the issue will be fixed, but right now the whole system is unstable this way, not possible to be used at clients locations, remotely, with such risk of breaking.

seems like my Pi5 will collect some dust until this stabilises…

Raspberry Pi 
Original heatsink
PoE HAT 
Pimorone nvme BASE “HAT”
I saw video’s of having to manually change configuration to get the Pi5 to boot off of the NVME drive, do we know if they are working on making it possible to boot off of nvme drives in HA. ?
I have RPi5 8Gb with Pimoroni NVME Base + SSD Samsung 980 500Gb connected through NVME (not USB)
I’ve spent several days trying to make HA works on this setup with huge number of fails.
Short story:
The main issue was with Raspberry Pi Imager - it makes not bootable image on SSD or SD Card. Once I’ve used Balena Etcher - HA starts to boot from the SSD (or SD, I tried both).
Long story:
I have old RPi3 with 1Gb RAM and experienced some troubles with Sonoff Zigbee 3.0 USB dongle when Zigbee2MQTT addon going to reset preiodically. I think because of out of RAM memory and freeze during swap activated watchdog to reset the addon. So, I decided to move to more powerfull HW. I’ve made an HA backup with all addons switched Off option for “Start on boot”, because I saw a topic with the issue specifically with RPi5 and HAOS 11.4 related on this.
I’ve flashed Rasperry OS lite via Raspberry Pi imager on SD card and made a first boot of RPi5 - all worked well.
I’ve changed
sudo rpi-eeprom-config --edit
by adding PCIE_PROBE=1 and changing boot order to NVMe SSD by BOOT_ORDER=0xf416
after that I’ve flashed haos_rpi5-64-11.4.img.xz on SSD and rebooted RPi5 without SD card with expectation to see the installation screen over http, but nothing happened. I’ve tried different releases like 11.3.rc1, 11.3., 11.4.rc1 with the same result (no boot). I always have used Raspberry PI imager for it, because it provides possibility to set WiFi settings and other useful options.
But when I flashed Raspberry OS on the SSD (or SD card) - it boots and works well, without any problems.
During the investigation I’ve updated eeprom
sudo nano /etc/default/rpi-eeprom-update
change the FIRMWARE_RELEASE_STATUS from “default” to “latest”
sudo apt update
sudo apt full-upgrade
sudo reboot
sudo rpi-eeprom-update
This should report at least firmware 2023-12-06 or higher.
It didn’t change anything, but good to have latest version.
So, finally I’ve used Balena Etcher to flash HAOS 11.4 image on SSD and it started to boot, showed installation screen in web browser and I used the backup to restore all my HA configuration.
The addons Mosquitto broker and Zigbee2MQTT started automatically, even with Start On Boot switched Off, I’ve just switched them On and made a full reboot.
I tried to full, quick and power disconnection reboot - without any problems. It booting every time now without any problems.
I hope it helps to other readers of this forum.
