I'd say keep a different instance for long-term data. This could be another prometheus, which gets data from the first one, e.g. using federation <https://prometheus.io/docs/prometheus/latest/federation/> or remote write. Or it could be some completely different system <https://prometheus.io/docs/operating/integrations/#remote-endpoints-and-storage> that it remote writes <https://prometheus.io/docs/prometheus/latest/storage/#remote-storage-integrations> to.
