Determine Which Data Privacy Record to Retain when Merging Records
We've simplified the process to merge leads and contacts that have corresponding data privacy records. If you’d prefer to always retain the most recently modified data privacy record, you can specify that preference in Setup. Just enter Individual Settings in the Quick Find box, and then select Individual Settings. Then select Retain the most recently modified data privacy record.
