When you need to transfer metadata ownership from one user to another for all or specific metadata records, use the Transfer Ownership option.
How to open the Transfer Ownership page*
From the « actions on selected set » in the search, the Portal displays the following panel.
Select New Owner: Select a user in this auto-complete.
The drop down is filled with all Editors visible to you. If you are not an Administrator, you will view only a subset of all Editors.
Select group: Select one of the groups this user is a member of. Privileges to groups All and Intranet are not transferable.
