When you move a user group to a new security domain, the target security domain owns the user group, but the user group members are still owned by the security domains to which they are assigned.
In the Security Console, click Identity > User Groups > Manage Existing.
Select the checkbox next to the user group that you want to move.
From the Action menu, select Move to Security Domain, and click Go.
From the Move to Security Domain drop-down list, select the security domain to which you want to move the user group.
