To amplify my remarks, yes, my context is strictly technical. The OP asked for a unemotional, pragmatic response to a somewhat specific technical question.
The chances of a SLA impacting problem does not change in the slightest. Now, the potential cost of fixing such a problem does increase once 'support' ends. And that cost might include both clock time as well as money. But how often do you hit such problems even when under support?

This is different from the risk, which could be high even in a low-probability situation. The OP has a tough job; multiplying a small probability of failure (which estimate is shaky at best) times a dollar amount arbitrarily assigned to loss-of-service to the business -- an equally dubious figure. <little probabilities> X <big losses> is likely yielding a net expected gain, which is why they're moving to peecees. But they shouldn't be looking *only* at expected gain, 'cause sometimes you get a bad beat. -- David Andrews A. Duda and Sons, Inc.
