But it makes sense to be resistant - you're trying to change something that they perceive to have worked for 25 years (or whatever). I bet that if they perceive that something to not work they'd accept that fix, but despite what some will say, more often than not if something isn't broken then it is a bad idea to try and fix it.

Part of gaining experience over the years is also gaining the experience that people often want to mess things that work (often with good intentions) and end up making things worse.
