[Talking about prometheus only here] You can change labels within PromQL expressions in queries: https://prometheus.io/docs/prometheus/latest/querying/functions/#label_replace
And you can use recording rules to generate new timeseries with the result of those queries. But changing the labels *inside* the database on *already scraped* data? I haven't seen anything like that. If you can export and re-ingest the corrected data, e.g. using backfilling <https://prometheus.io/docs/prometheus/latest/storage/#backfilling-from-openmetrics-format>, then you can delete the old timeseries <https://prometheus.io/docs/prometheus/latest/querying/api/#delete-series>.
