I can't migrate automations in UI

Configuration
1

Does anyone know what the problem might be? I can no longer migrate my automations in the UI; everything remains grayed out. This started after I updated to Home Assistant Core 2025.12.0. Home Assistant Core 2025.12.1 and 2025.12.2 also have the same problem. If I go back to Home Assistant Core 2025.11.3, I can migrate again in the UI.
My configuration.yaml

homeassistant:
  packages: !include_dir_named packages/

# !include yaml files
automation: !include_dir_merge_list automations/

My automations are in:
CONFIG → automations → abcdefg.yaml (etc…)
CONFIG → packages → abcdefg.yaml (etc…)

Installation method: Home Assistant OS
Core: 2025.12.2
Supervisor: 2025.12.2
Operating System: 16.3
Frontend: 20251105.1

I would guess this is because the UI puts all the automations in a single file, so using !include_dir_merge_list breaks this. The fix is to do something like below where you give a name to your automations folder and put all the UI automations in a single automations.yaml file:

automation myfiles: !include_dir_merge_list automations/
automation: !include automations.yaml

That’s a good hint and I wounder, why the default config of HA ist that bad.

I tried what you said, but unfortunately, it doesn’t work. When I try to migrate a file, everything is grayed out, and I can’t even edit the automation.

I’ve got the same problem after upgrade to 2025.12. Nothing in the logs for any help either. When i press migrate, nothing happens at all.

For those of you struggling with the same problem, just go to automations overview in UI, click the three dots to the right and duplicate, save.
