Removal of Supervisor

Hello all!
Many years ago I started one automation using FHEM. It’s running in a Raspi 4B with recent Raspberian (based on Debian bullseye). Last spring I discovered HA and loved the interface, which also has a high WAF (woman acceptance factor). I installed HA on the same Raspi as FHEM, but in a docker. The installation is with supervisor which was supported till last autumn.
Since the policy for installation of supervisor has changed a couple of moths ago I can’t update the supervisor-component either and sooner or later it will be very outdated.
I’m considering a new installation of my system from scratch w/o supervisor (but still using HACS). However, I am worried about the onboarding when I’m going to import the last backup. Will it be a problem to onboard a configuration which was made with supervisor installed in a fresh installation without supervisor installed?
Furthermore; what does it mean for me having an installation w/o supervisor (e.g.: Raspberry Pi - Home Assistant ) ? Is there much more effort to maintain the system than today?

Thank you for your answers!

That won’t happen. Supervisor restores backups, not HA. No Supervisor means no restoring backups, you won’t be prompted for one during onboarding.

However you can extract a backup and copy the contents of the HA config folder from the backip into the config folder for your new HA container. The config will work with or without supervisor.

There are no addons without supervisor though. So any addons in your backup can’t be restored. You’ll need to find public docker images for them and configure and run your own containers from those images.

Thank you very much, although this is not what I like (expected/hoped) to read.
