-- You should understand the implications of changing a group's path or name.
-- For more information, see <http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_WorkingWithGroupsAndUsers.html Renaming Users and Groups> in the /Using IAM/ guide.
-- To change a group name the requester must have appropriate permissions on
-- both the source object and the target object. For example, to change Managers
-- to MGRs, the entity making the request must have permission on Managers and
-- MGRs, or must have permission on all (*). For more information about
-- permissions, see Permissions and Policies.
