Undoing a Merge

If you merge two patient profiles or system records in error, you can unmerge the profiles or records, moving the information back into the original patient profiles or system records. Any modifications that were made to the surviving patient profile or system record after the merge are retained after the profiles or records are unmerged. If a system record merge caused the “merge from” patient profile to be deactivated, unmerging the system records reactivates that profile.
