Best way to reset a duplicate node

Somehow along a couple computer upgrades and moves I’ve ended up with a cloned machine and thus a cloned node. What’s the best way to ‘reset’ a node of its ID, etc. Oddly, the synching seems to be working still for many of the shared folders—I’m not sure how.

If you delete the key files (see https://docs.syncthing.net/users/config.html), the ID will be automatically reset without touching the rest of your local configuration.
