Migrate History Stats from yaml to UI

I have some History Stats configured in yaml and a couple of releases ago HomeAssistant released History Stats setup via the UI.

But after the release none of my yaml configs where migrated automatically to the UI. Normally this would be the case right? As many Integrations do this after they are updated to be able to be set up by the UI.

Did I do something wrong or do I really have to migrate all this manually?
