Find the user records to be merged: From Open up the uncleared user record you wish to merge, and under the Process tab, click Merge User.
This will open up the “Users waiting to be cleared” window; from here, use the search box to search for the two users you wish to merge (could search using the surname, email address, etc.).
Note: To access the “users waiting to be cleared” window, you may need to open an uncleared user record, and click “Merge user” in the top ribbon.
In the example below, we know that Elise Ciregna and M. Ciregna are the same person because they have the same email address.
...
Once you’ve found the two users you wish to merge, you may want to review each record to determine which record to keep and which to disavow (generally the record with contact information that is more complete or more up to date record is the one record you should keep.Once you’ve made this determination, highlight ).
If the record you wish to keep is not cleared:
Highlight the record you wish to keep in the left hand window (“Users to be cleared”), and highlight the record you wish to disavow in the right hand window (“Similar users.”). If you don’t readily see the duplicate user in the “Similar users” window, right-click in that window and select “Show all users”, then browse to the correct user record.
...
In the next window, select the second option, “Disavow “Disavow Existing User and Clear New User.”
If the record you wish to keep is cleared:
Then will only appear in the "Similar Users" window on the right. Highlight the record you wish to keep in the right hand window, and highlight the record you wish to merge/disavow in the left window. Then click Merge User" at the top, and in the next window click "Keep Existing User and Disavow New User".
Short version:
If the record you want to keep is cleared, highlight it on the right, highlight the other on the left, and choose the "Keep Existing User and Disavow New User" button on the left.
If the record you want to keep is uncleared, highlight it on the left, highlight the other on the right, and choose the "Disavow Existing User and Clear New User" button on the right.
