Event Replicator

Last updated:

|Edit this page

The Replicator app copies events from one PostHog instance to another, at the moment they are ingested. No changes are made to the events by this app if it runs in isolation.

If this app is deployed in a chain then any changes made to the event data before the Replicator runs will also be copied to the new instance. Otherwise, no changes will be copied.

Note: If you want to export previous ingested (old) events, use batch exports.

Requirements

The Replicator app requires two instances of PostHog running either PostHog Cloud, or a self-hosted PostHog instance running version 1.30.0 or later. The source instance needs to subscribe to the data pipeline add-on.

Not running 1.30.0? Find out how to update your self-hosted PostHog deployment!

Both versions of PostHog should ideally be running the same version.

Using the Replicator app

  1. Log in to your PostHog instance
  2. Click "Data pipeline" in the left sidebar
  3. Search for 'Replicator'
  4. Select the app, press 'Install' and follow the on-screen instructions
  5. See events come into another PostHog instance, identically to the originals
