I'm using xDB Data Migration Tool 2.0 to migrate data from MongoDB (Sitecore 8.2) to xconnect (Sitecore 9.0.2). The tool runs without errors for around 60k records. Then it breaks with Errors like the following :
Operation #90, ReferenceNotFound, Interaction, LegacyXdb (pipeline: Process Single Interaction from MongoDB Pipeline, pipeline step: Add Interaction Model to xConnect Batch, pipeline step identifier: 7cd619a9-1ce0-44da-bf42-22736247667c)
I've confirmed that the JSON file for the facets has been deployed to the xconnect service and the xconnectSearch service.
Does anyone know what could be causing this?
