Legacy xDB Facet

Format in Sitecore 8.x

In Sitecore 8.x, each interaction has a unique identifier. This identifier is the document id, which is stored in a property named _id.

The following is an example of an interaction with the _id property:

"_id" : NUUID("ac95ec0b-fba0-466b-8b51-a2f3e887e1d2"),

Format in Sitecore 9

When an interaction from Sitecore 8.x is migrated to Sitecore 9, xConnect generates a new id for the interaction. The interaction id from Sitecore 8.x is associated with the interaction through an interaction facet:

Facet Name LegacyXdb
Facet Type Sitecore.DataExchange.Tools.XdbDataMigration.Models.DataMigrationCollectionModel
