Not sure we can wait much longer for an OOTB solution (Idea: EVM History 'Roll Off' Functionality). I have a prototype running. Is anyone else purging old EVM data today? If you are - I prefer not to re-invent wheels, or at least I'd like to compare notes & validate the wheel we're prototyping. Probably best to message me on LinkedIn (http://www.linkedin.com/in/robertensinger).
