Migrade from 32-bit Pi3 to 64-bit Intel NUC

Hi,

Currently running HaOS 32-bit on a Pi3 and I want to migrate to a Intel NUC with HaOS 64-bit.

I have an Zigbee, ZWave and P1 smart meter reader connected.

Also running the following add-ins:

  • AdGuard
  • Wireguard
  • DuckDNS
  • File editor
  • Google Drive Backup
  • Log viewer
  • Mosquitto broker
  • Samba share
  • Terminal & SSH
  • ZWave JS

Can I install a clean 64 bit HaOS on the intel nuc and restore a full backup from the Pi3?
Will this result in 64 or 32 bit add-ons?

Anything I else I should consider?

Works fine - the HA backup is basically a reinstall then re-apply saved configuration on top of that. It’s not hardware dependent for that.

Does it also include HACS stuff?

everything. It’s how I moved from Supervised to HAOS.

Install the machine new - and either provide the backup file after the install comes up, or you can create a dummy account, load in the backup file and restore.

The biggest thing you need to watch out for - if you’re using Zigbee., Zwave, etc and are NOT using the By-ID address to tell your integrations where they’re plugged in and instead are using the virtual USB ports, you may have to reset the location in those add ins if the ports change when you move. But if you ensure you’re using by-id addressing in the backup it should translate and ‘just work.’

The hardest thing I had was trying to figure out the best way to get the backup file on the new box.

Also - Rollback plan:

if you’re moving between boxes, just backup the old - save your backup file, then turn off the old box. Keep it off until you KNOW your new box is working (don’t change ANY credentials until you know you’re staying on the new install, that will prevent you from going back without changing anything.) If something is broken just shut down the new box and turn on the old until you figure out what broke then redo your migration.

Once you’re sure the new box is working then just recycle ore rebuild the old box for it’s new use.

Thanks for sharing your advice and experience.

And advice on the best way to get the backup file on the new box? I was planning to use an USB stick

I personally used the method of logging in with a dummy account.

Installed Google Drive Backup, then downloaded from there. I wasn’t in a hurry.

Just have a copy of the backup on the PC that you’re using to access the web interface.
