OK I have HA running on a PI 5 and works great. I added the official M.2 Pi Hat and a 512GB SSD. Its currently running on a 64Gb SD card. What is the EASIEST way to migrate it to SSD with minimal disruption? I added a 7" HDMI screen, mouse, keyboard to access it directly, but get the HA prompt not the PI prompt, so not very helpful. I have many plugins and would rather not start from scratch. Thanks.
That’s two different questions.
The first. Best way is to:
- backup the machine
- Reinstall from scratch to the SSD.
- then restore your backup.
You’ll end up with everything you have now. Booting from SSD.
As. To the other. That’s what you should see. The machine is a server not a client. That’s the console… And why people say you shouldn’t do it that way. To get the experience you want you need to have a second client running a browser or the companion driving that screen. There may also be an addon… Er app fhat does it…
But out of the box. That’s the expectation. Ha console.
So System, Backups? What directory are they stored in? So SD card will do nothing after that? Will it use the full SSD (512GB) not just the 64GB SD card size?
Make a full backup in HA, when done download the backup to your pc, do a fresh install on the SSD and restore the backup. All 512Gb will be available.
Don’t forget to update the Rpi bootloader if you want to boot from the SSD.
Using external data disk
Home Assistant Operating System supports storing data on a secondary storage medium. For example, this can be a second internal SSD or HDD or a USB attached SSD or HDD. This data disk contains not only user data but also most of the Home Assistant software as well (Core, Supervisor, etc.). This means a fast data disk will make the system overall much faster.
One tip not mentioned, do not delete your original setup on the SD card until you new setup is running, you can then just revert if it goes wrong.
Another tip, setup backups to an external source either nas or Google drive before going anywhere, you will need it oneday, it may even be useful today you never know.
Actually, if you choose the EASIEST way just linked (external data disk) better don’t delete or remove your SD card at all because it will break your system
