Once a model version is attempted to be deployed, a Model Version Endpoint is created. If the deployment is successful, the endpoint would be in the Running state. This endpoint can later also be terminated.
Whenever a running (or serving) model version is redeployed, a new deployment is created and the Merlin API server attempts to deploy it, while keep the existing deployment running (or serving).
If the deployment of the new configuration fails, the old deployment stays deployed and remains as the current deployment of the model version. The new configuration will then show a 'Failed' status.
A model version can be redeployed via the SDK or the UI.

version = model.get_version(2)
# Redeploy using new config (here, we are updating the deployment mode)
new_endpoint = merlin.deploy(v, deployment_mode=DeploymentMode.RAW_DEPLOYMENT){% endcode %}
A Running / Serving model version can be redeployed from the model versions view.
