+On this page, you'll learn how to set up the destination that you'll use to get started with [Trait Enrichment](/docs/unify/trait-activation/trait-enrichment/) and [ID Sync](/docs/unify/trait-activation/id-sync/).

+
+## Resyncs
+
+Segment recommends creating a new Audience for Trait Enrichment and ID Sync. For existing Audience destinations, both Trait Enrichment and ID Sync don't automatically resync the entire Audience. Only new data flowing into Segment will adhere to new trait criteria. 
+
+[Contact Segment support](https://segment.com/help/contact/){:target="_blank"} if you'd like your Audience data resynced with Trait Enrichment and ID Sync. 
+
+> warning ""
+> For Audiences larger than 50 million users, it may take up to several hours or even days, to sync or resync. Only one resync is allowed at a time for each workspace.
