Getting "invalid password for backup" trying to restore from unsupported to haos

I’m currently using Home Assistant installed as a docker image (core + supervised) on a Synology nas. HA version 2025.1.4 and supervisor 2025.01.2.dev3103.
I’ve done a backup, noted the encryption key and powered on the new machine. Raspberry pi 5, with nvme, haos 2025.1.4.
I’m at the onboarding step and i can’t restore the backup made on the other machine. I’m sure the encryptin key is the right one, but i get this message … Invalid password for backup c032d02c.

Backing up with Google Drive Backup is not a solution because i can’t install the add-on. Error… system not healthy.

Main questions:
Is it possible to restore to supported machine backups made on unsupported?
I’ve read that 2025.2 will be able to generate unencrypted backups. Should I wait for this release or it’s a lost cause?

Thank you!

2025.2 should arrive today.

The first layout is looking like this
It is not set in stone, but it indicates that a lot will happen with the backup features.

It worked like a charm in 2025.2.0 The version must be the same.

I encountered exactly the same issue. @mandgeo : did you found a solution to restore the back-up?
