Standard-Volume Platform Events Retirement

What action do I need to take to complete a manual migration of Standard-Volume Platform Events?

Replace all existing standard-volume platform events with high-volume platform events. To do this you can either migrate your existing standard-volume platform events to high-volume platform events or you can recreate your platform events from scratch.

To migrate your existing standard-volume platform events, ensure all publish activity has stopped and all subscribers, including triggers and flows, are done processing. Then go to Setup —> Platform Events and click the migrate button. This will migrate all of your standard-volume platform events to high-volume platform events and should take about 15 minutes, although the migration can take longer, up to 24 hours. You will receive an email when each event has been migrated. While the migration is running, publishes won’t work and you’ll be unable to create new triggers or flows until the migration finishes.

When you create a platform event, it is high-volume by default. To create a platform event from scratch, follow these steps. 

1. From Setup, enter Platform Events in the Quick Find box, then select Platform Events.

2. On the Platform Events page, click New Platform Event.

3. Complete the standard fields. See Platform Event Fields in the Platform Events Developer Guide for more information.

4. Add the event fields.

Update all the automation and integration apps, such as flows, processes, Apex triggers, and Streaming API clients, that reference the standard-volume platform events with the new high-volume platform events.

To prevent any event loss, complete processing your standard-volume platform events before transitioning to high-volume platform events by following these steps.

1. Create an equivalent high-volume platform event in your org.

2. Stop the publishing process for all standard-volume events.

3. Process all remaining standard-volume events. (If this isn't possible via your business logic, you will have to wait 72 hours after stopping your event publishing to let all standard-volume events expire.)

4. Deactivate your standard-volume event subscriptions and delete all related artifacts (triggers, event definitions, etc.)

5. Start your high-volume platform event publish process and subscriptions.
