You can remove rules from the Real-time Rules folder, thereby “un-deploying” them from the live system.
To un-deploy a rule (beyond disabling it), select the rule in the Real-time Rules folder, right-click, and choose Delete Rule from the context menu.
Depending on whether the rule was linked, moved, or copied into the Real-time Rules folder, you get different options at this point.
If the rule has been moved or copied into your working folder, you get an option to remove it or to cancel the operation.
If the rule is a link to the original rule in your working folder, you get options to remove it from this group only, delete it entirely from all locations, or cancel the operation. A linked file is treated as a single entity, so edit actions taken on the file in any location affect all instances of it.
