An animation of the migration. Your apps and databases sync through Azure Data Factory while Weld's team maps every connector, then both run in parallel into your warehouse until the row counts match, and finally Azure Data Factory is switched off while Weld keeps syncing and orchestrates the dbt run after each sync.
