If something comes down the MS upgrade channel that overnight obsoletes the boxes those 3500 users are running on you'll happily put your hand in your business's pocket & write out an order for 3500 new boxes, won't you?
I once ran a Unix unit in a shop where the IT management had a similar one stop shop mentality. They were going to replace my system in 6 months time. For years and years. Eventually I retired. I regret not being there to see what happened in the end. Their one stop shop was for VAX/VMS.
