Duplicates can be created when the constituent record in Core does not match the Raiser's Edge record, for example. It is recommended that when merging duplicate records in Raiser's Edge, users retain the record linked to the matching Core record as the master record and delete the duplicate, unlinked record.

Should users decide to retain the unlinked record in Raiser's Edge and remove the linked record the result would require users to re-match and process the records the next time the affected record syncs to Connect RE.
