Hi Gert
Merges should take place as the higher profile number being merges into the lower number - so Myburg-48 should be merged into Myburg-11.
During the merge process, you have the opportunity to select the fields in the final version, (see the green and yellow fields on the merge page). So if one has a birthdate of about 1670 and the other has dob as May 1, 1671 you can check the correct so that it appears in the final record. Last/Right hand column shows what is being kept.
Once a merge is complete, the new profile will contain details from both of the original profiles.
The biography will contain all the information from both profiles and should be edited once the merge is complete. Removing redundancies, organized etc.
To view all the changes that have occured with either profile, click the CHANGES Tab, that is found in the Tab row across the top of the final profile. This page shows all the edits and when they were done. You can click on any edit - and then see previous or next change by clicking those buttons.
