There are a few instances where you would want to copy a Group. Copying a Group is an easy way to replicate a group of users without having to rebuild it from scratch.
Go to the Groups page. Select the downward facing arrow associated with the Group you want to replicate. From the drop down, select Copy.
Type a name for your new group. You will notice the default title of your new Group includes, “COPY OF.” You can change the title of the Group if you wish but it cannot be the same title as the Group you copied.
Click the Create button. You've now created a copy of the existing Group.
