This app is currently unavailable while we develop a new export system. It will be back again soon!
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.
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.
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
To migrate your events, we'll be using the PostHog Replicator app:
- Disable the GeoIP plugin of your new PostHog instance
- Log in to your old PostHog instance
- Click 'Apps' on the left-hand tool bar
- Search for 'Replicator'
- If self-hosted, select the app, press 'Install' (or make sure it's the latest version)
- For the configuration details using the following:
Host: the hostname of your new PostHog instance e.g.app.posthog.comif you are using US cloud,eu.posthog.comif you were are EU cloud, or the domain you'll be sending events to if you are self-hostingProject API Key: the API key for the new project that you want to send events to - found in the project settings page.
- After clicking save and activating it (toggle on the left side), the Replicator will start to run. Any events added to your old instance will be replicated in your new instance. It can take a little while (15-20 minutes) for the first events to show up.
- Once the Replicator is activated, go back to the configuration menu and click the gear next to "Export historical events" under "Jobs." On the calendar, select a start and end date, then click "Run job now." This will begin the process of historical events being import (and might take a while). You can see the progress in logs or by clicking the "App metrics" button (graph) and going to the "Historical exports" tab.
- To track progress of the export you can click the graph icon next to the Replicator app and then click on the "Historical Exports" tab
- Re-enable the GeoIP plugin of your new PostHog instance
- Log in to your PostHog instance
- Click 'Apps' on the left-hand tool bar
- Search for 'Replicator'
- Select the app, press 'Install' and follow the on-screen instructions
- See events come into another PostHog instance, identically to the originals
