Moving to a new Raspberry PI

This may be a stupid question, mine normally are, so I appologise in advance.

I have Hassio on a Pi3 and it’s been working fine for a few years, last night the red light started flashing and HA was not accessable. I figured it was to do with the power, plugged a firestick power lead in and back up and running, left it half an hour and then plugged the original power lead back in and all was good. This has made me wonder if it’s time to upgrade to a Pi4 or 5?

If I do, what is the process of transferring my current setup to the new PI?

  1. can I just put my existing SD card in the new PI and off it goes Hassio boots up and all as was?
  2. do i need to do a backup of my existing, install a fresh on new PI and then restore the back up from old one?
  3. because new PI’s have different processors etc, do I need to set everything up from scratch again?

or is there another way I have not thought about?


Correct. There are separate images for pi3, pi4 and pi5

No, restore your backup and you are fine.

And , hassio is already 4 years dead. It is called Home Assistant OS now, or HA OS in short.

Best to find out why it is failing first. Most probably the SD card failing which will not be solved if you put it in a pi4.

If you are buying a new pi4, don’t bother go for something like a second hand NUC or thin client. More power for less or similar cash, and less issues with power and sd cards. plenty of guides on youtube.

Downside to NUC or thin client is much higher power consumption, so higher running cost. So if you need the power go for NUC. If you don’t and cost is a factor, then decide knowing it may look the same price but it isn’t the same long term.

Please correct me if I’m wrong, but I thought one advantage to the RPi line is that there are “canned” HA installations available. In other words, no messing with setting up the OS, then layering HA on top of that. Obviously some would see that as a disadvantage, but I figured it was worth noting.

HAOS runs on NUC or x86 based hardware.

The power consumption may be higher but by the time you add ssd drives and powered hubs to a pi, (needed for reliability) you are probably not talking a lot. and the advantage is in a years time when you inevitably want a more powerful system, you will have one.

Agree you should troubleshoot your crashes first. Why spend extra money and time for a new platform if you don’t have too?

And your SD card may be ok but the files on it might be corrupted from the crash.

Thanks for the replies. This is the first time it has happened, never had the red flashing light before, I am just preparing myself if it happens again, so looking at what is involved in ‘upgrading’

I must admit I don’t know what a NUC, I do have an old laptop with linux installed that’s not used and did think about installing on that but that does seem like a bit of an overkill for my simple setup, apart from the SD I don’t have any extra’s plugged into it.
