Changing environment from Cattle to Kubernetes

Has anyone tried updating an existing environment that is using the Cattle engine to a Kubernetes when you have deployed stacks? does that work or is it better to start with a fresh environment?
Curious if the stacks themselves convert.

Everything technically works (and kubernetes is actually deployed as a cattle template) but the UI won’t show the user cattle stacks anymore.

So there wouldn’t be a way to control those stacks anymore? Even to deactivate/delete them?

Correct, the stacks wouldn’t show up at all in the UI under stacks.
