### Disallow configuring Alertmanager with the v1 API
Prometheus 3 no longer supports Alertmanager's v1 API. Effectively Prometheus 3
requires [Alertmanager 0.16.0](https://github.com/prometheus/alertmanager/releases/tag/v0.16.0) or later. Users with older Alertmanager
versions or configurations that use `alerting: alertmanagers: [api_version: v1]`
need to upgrade Alertmanager and change their configuration to use `api_version: v2`.
# Prometheus 2.0 migration guide
For the Prometheus 1.8 to 2.0 please refer to the [Prometheus v2.55 documentation](https://prometheus.io/docs/prometheus/2.55/migration/).
