From the Patient tab do a search for the patient profiles you want to merge.
To the left of the patient profile click the down arrow and select Merge.
The next page gives you the profile information and a list of profiles that have similar names. The profile on the right is the one that will be kept. The one on the left will be deleted.
Click the radio button beside the one you want to merge and select Next.
On the next page, the profile you are going to delete is on the left, the right side shows the profile that will be saved. A profile is never completely deleted, you will still have access to it when you do a Patient search for Deleted profiles.
You can move fields from the left to the right based by clicking the blue arrows on fields you want to move.
At the bottom type YES and select Merge.
Now the 2 profiles will be merged.
The deleted patient profile will always be stored in the "deleted" patient list.
