I may be missing something but at least in LV 2010, it appears only possible to replace a "Diagram Disable Structure" by a "Conditional Diagram Disable Structure".
I don't see why it is not possible to replace it by a case structure... The content is very similar and I have faced occurences where I would toy around between different versions of my code and eventually decided that I wanted to offer the user the possibility to choose between them using an enumerated control (or Boolean). Currently you have to rewrite the code in a newly dropped case structure, which is a waste of time. I guess I could stop using Diagram Disable structures altogether, but I most of the time use them for their intended use, so that would be a step backward in functionality if I forced myself to use case structures "in case" I would later want to offer these different cases to the user (which is something that I can't always predict).
