Under the Usage Rate Groups heading select the rate group you wish to clone
In the same panel click on the icon
Enter a Name, Display Name and Start Date for the cloned rate group
Click the Clone button
Modify the rate group further if needed (add time periods, conditions, etc.)
Click Save when finished to create the new rate group
