Glad to see that todays problems are the same everywhere <G>.
With what you mention, it's one of the reasons that with DSR we kept it simple. Put in the open systems so that we can improve and add to them later. Make the transition as easy as possible. We had some facilities cutting over in one or two days in a big bang. Our facility was one of the first BIG facilities to cut over and we were very conservative...
By the way, is there anyway to attach pictures on this board?
