If you need a new identity attribute definition that is similar to an existing one, you can duplicate and customize an existing one.
In the Security Console, click Identity > Identity Attribute Definitions > Manage Existing.
On the Identity Attribute Definitions page, use the search fields to find the identity attribute definition that you want to duplicate.
Select the identity attribute definitions that you want to duplicate.
From the drop-down menu, click Duplicate.
The system displays the Add New Identity Attributes Definitions page with the values provided from the original identity attribute definition.
Perform steps 2 - 11 in Add an Identity Attribute Definition.
