Migrate HAOS from aarch64 to x64

Installation Home Assistant OS
1

Hi,

I want to switch from an Odroid M1 (aarch64) to x64 hardware. On the Odroid I use the eMMC together with a 1TB NVMe SSD as “external” data device.

I tried to just plug the same SSD to the new hardware but the system did not start up because all the already installed containers (including Home Assistant) are for the aarch64 architecture.

Is there a way to re-use the SSD on a new architecture? Backup, restore and re-move to the SSD will get complicated because it will override all my data in /share, I think.

Thanks in advance

Thats not the same platform and will require a new install. You can restore your backup to maintain state bit no - it’s not just move the disk.

Thanks @NathanCu. So I have to backup and download the ~600GB, wipe the disk (or rename the part label) and upload and restore the whole data? Sounds like a mess.

It is what it is and what’s required… X64 simply cannot run arm binaries. You need to reinstall to put the binaries down and restore your config. If you’re already on Haos this is not a hard operation and in fact the exact same process you would do to restore form a fatal error with your backup.

Its good practice.

Sure and good to have all these tools at hand. But I hoped there is a “shorter” way to just replace the 10GB of containers instead of backup and restore 590GB of static data.
