Editing, Deleting and Copying Resource Groups

Before modifying a resource group, carefully examine the associated rules to understand how your changes will affect your security policy. You cannot delete a resource group that is referenced in an access control rule. Before deleting a resource group, you must first remove it from any rules in which it is referenced. See Deleting Referenced Objects for more details.

Rather than creating a new resource group from scratch, you can save time by making a copy of an existing group and changing some parameters to fit the new group. Choose a group that shares characteristics with the group you plan to create.
