The Migrator for Notes to Exchange (MNE) from Dell (formerly Quest) has by design a 1:1 dependency from source data to the used migration host. If you re-migrate the same data (a user collection) on different migration host you create doublicates of the sourcedata in the target mailbox. The MNE can´t detect that the same element exists in the target, because the attribute to identify has a host bound content part.
Same source Data – Same Migration Host
