Migrating from KAS installed via Docker to Helm

I’ve just upgraded our infrastructure to v15 and I’d like to upgrade our several KAS agents to match the version. I went to the docs and the only method for installation or upgrade now is through Helm. The issue is, the Helm method of installation either didn’t exist or wasn’t the command given when setting up the agents initially.

Now I’m not really sure how to proceed. We have a small but decent amount of applications deployed using KAS, so I’d really rather not destroy and recreate the agents for fear that they may take the applications with them when they go down, but there is no documented path to upgrade the agents using the old Docker-based command. Is there a way to seamlessly migrate the agents to being managed by Helm? Or is destroying the old agents and recreating them the only path forward here? Would that destroy the resources they manage?
