Migrating historical data from Cloud to Self-Hosted

[StrandedKitty]

I'm looking a way to migrate PostHog Cloud data collected over the last several month to a self-hosted PostHog instance.

Previously PostHog/posthog-plugin-replicator could do migrations, but it look like plugins were deprecated at some point.

I also found this guide that describes how historical data can be exported into S3, Postgres, etc. Not sure if it still works. If it does, I guess it might be possible to import it into the self-hosted instance in Data Pipeline > Sources tab.
